Given a {@link CodeGenerator}, obtains the generated + * source code, compiles it with the selected compiler, loads the + * byte-codes into a class loader and provides the resulting + * class.

+ * Here is how to use the plain Java technique to debug + * generated code: + *

    + *
  • Set the config option drill.exec.compile.code_dir + * to the location where you want to save the generated source + * code.
    • + *
  • Where you generate code (using a {@link CodeGenerator}), + * set the "plain Java" options:
    + * CodeGenerator<Foo> cg = ...
+ * cg.plainJavaCapable(true); // Class supports plain Java
+ * cg.preferPlainJava(true); // Actually generate plain Java
+ * cg.saveCodeForDebugging(true); // Save code for debugging
+ * ...
    + * Note that saveCodeForDebugging automatically sets the PJ + * option if the generator is capable. Call preferPlainJava + * only if you want to try PJ for this particular generated class + * without saving the generated code.
    • + *
  • In your favorite IDE, add to the code lookup path the + * code directory saved earlier. In Eclipse, for example, you do + * this in the debug configuration you will use to debug Drill.
    • + *
  • Set a breakpoint in template used for the generated code.
    • + *
  • Run Drill. The IDE will stop at your breakpoint.
    • + *
  • Step into the generated code. Examine class field and + * local variables. Have fun!
    • + *
+ *

+ * Most generated classes have been upgraded to support Plain Java + * compilation. Once this work is complete, the calls to + * plainJavaCapable can be removed as all generated classes + * will be capable. + *

      + *

      Basic Operation

      + * The operator has three key phases: + *

      + *

        + *
      • The load phase in which batches are read from upstream.
        • + *
      • The merge phase in which spilled batches are combined to + * reduce the number of files below the configured limit. (Best + * practice is to configure the system to avoid this phase.) + *
      • The delivery phase in which batches are combined to produce + * the final output.
        • + *
      + * During the load phase: + *

      + *

        + *
      • The incoming (upstream) operator provides a series of batches.
        • + *
      • This operator sorts each batch, and accumulates them in an in-memory + * buffer.
        • + *
      • If the in-memory buffer becomes too large, this operator selects + * a subset of the buffered batches to spill.
        • + *
      • Each spill set is merged to create a new, sorted collection of + * batches, and each is spilled to disk.
        • + *
      • To allow the use of multiple disk storage, each spill group is written + * round-robin to a set of spill directories.
        • + *
      + *

      + * Data is spilled to disk as a "run". A run consists of one or more (typically + * many) batches, each of which is itself a sorted run of records. + *

      + * During the sort/merge phase: + *

      + *

        + *
      • When the input operator is complete, this operator merges the accumulated + * batches (which may be all in memory or partially on disk), and returns + * them to the output (downstream) operator in chunks of no more than + * 64K records.
        • + *
      • The final merge must combine a collection of in-memory and spilled + * batches. Several limits apply to the maximum "width" of this merge. For + * example, each open spill run consumes a file handle, and we may wish + * to limit the number of file handles. Further, memory must hold one batch + * from each run, so we may need to reduce the number of runs so that the + * remaining runs can fit into memory. A consolidation phase combines + * in-memory and spilled batches prior to the final merge to control final + * merge width.
        • + *
      • A special case occurs if no batches were spilled. In this case, the input + * batches are sorted in memory without merging.
        • + *
      + *

      + * Many complex details are involved in doing the above; the details are explained + * in the methods of this class. + *

      + *

      Configuration Options

      + *
      + *
      drill.exec.sort.external.spill.fs
      + *
      The file system (file://, hdfs://, etc.) of the spill directory.
      + *
      drill.exec.sort.external.spill.directories
      + *
      The comma delimited list of directories, on the above file + * system, to which to spill files in round-robin fashion. The query will + * fail if any one of the directories becomes full. + *
      drill.exec.sort.external.spill.file_size
      + *
      Target size for first-generation spill files Set this to large + * enough to get nice long writes, but not so large that spill directories + * are overwhelmed.
      + *
      drill.exec.sort.external.mem_limit
      + *
      Maximum memory to use for the in-memory buffer. (Primarily for testing.)
      + *
      drill.exec.sort.external.batch_limit
      + *
      Maximum number of batches to hold in memory. (Primarily for testing.)
      + *
      drill.exec.sort.external.spill.max_count
      + *
      Maximum number of batches to add to “first generation” files. + * Defaults to 0 (no limit). (Primarily for testing.)
      + *
      drill.exec.sort.external.spill.min_count
      + *
      Minimum number of batches to add to “first generation” files. + * Defaults to 0 (no limit). (Primarily for testing.)
      + *
      drill.exec.sort.external.merge_limit
      + *
      Sets the maximum number of runs to be merged in a single pass (limits + * the number of open files.)
      + *
      + *

      + * The memory limit observed by this operator is the lesser of: + *

        + *
      • The maximum allocation allowed the allocator assigned to this batch + * as set by the Foreman, or
        • + *
      • The maximum limit configured in the mem_limit parameter above. (Primarily for + * testing.
        • + *
      + *

      Output

      + * It is helpful to note that the sort operator will produce one of two kinds of + * output batches. + *
        + *
      • A large output with sv4 if data is sorted in memory. The sv4 addresses + * the entire in-memory sort set. A selection vector remover will copy results + * into new batches of a size determined by that operator.
        • + *
      • A series of batches, without a selection vector, if the sort spills to + * disk. In this case, the downstream operator will still be a selection vector + * remover, but there is nothing for that operator to remove. Each batch is + * of the size set by {@link #MAX_MERGED_BATCH_SIZE}.
        • + *
      + * Note that, even in the in-memory sort case, this operator could do the copying + * to eliminate the extra selection vector remover. That is left as an exercise + * for another time. + *

      Logging

      + * Logging in this operator serves two purposes: + *
    • + *
        + *
      • Normal diagnostic information.
        • + *
      • Capturing the essence of the operator functionality for analysis in unit + * tests.

The data source operates in two modes: + *

        + *
      • Classic: used in physical plans in many unit tests. + * The plan specifies a set of columns; data is generated by the + * vectors themselves based on two alternating values.
        • + *
      • Enhanced: available for use in newer unit tests. + * Enhances the physical plan description to allow specifying a data + * generator class (for various types, data formats, etc.) Also + * provides a data storage engine framework to allow using mock + * tables in SQL queries.
        • + *
      + *

      Classic Mode

      + * Create a scan operator that looks like the following (from + * /src/test/resources/functions/cast/two_way_implicit_cast.json, + * used in {@link TestReverseImplicitCast}): + * 
      
+ *    graph:[
+ *        {
+ *            @id:1,
+ *            pop:"mock-scan",
+ *            url: "http://apache.org",
+ *            entries:[
+ *                {records: 1, types: [
+ *                    {name: "col1", type: "FLOAT4", mode: "REQUIRED"},
+ *                    {name: "col2", type: "FLOAT8", mode: "REQUIRED"}
+ *                ]}
+ *            ]
+ *        },
+ *    }, ...
+ *
      + * Here: + *
        + *
      • The pop must be mock-scan.
        • + *
      • The url is unused.
        • + *
      • The entries section can have one or more entries. If + * more than one entry, the storage engine will enable parallel scans + * up to the number of entries, as though each entry was a different + * file or group.
        • + *
      • The entry name is arbitrary, though color names seem + * to be the traditional names used in Drill tests.
        • + *
      • The type is one of the supported Drill + * {@link MinorType} names.
        • + *
      • The mode is one of the supported Drill + * {@link DataMode} names: usually OPTIONAL or REQUIRED.
        • + *
      + *

      + * Recent extensions include: + *

        + *
      • repeat in either the "entry" or "record" elements allow + * repeating entries (simulating multiple blocks or row groups) and + * repeating fields (easily create a dozen fields of some type.)
        • + *
      • generator in a field definition lets you specify a + * specific data generator (see below.) + *
      • properties in a field definition lets you pass + * generator-specific values to the data generator (such as, say + * a minimum and maximum value.)
        • + *
      + * + *

      Enhanced Mode

      + * Enhanced builds on the Classic mode to add additional capabilities. + * Enhanced mode can be used either in a physical plan or in SQL. Data + * is randomly generated over a wide range of values and can be + * controlled by custom generator classes. When + * in a physical plan, the records section has additional + * attributes as described in {@link MockTableDef.MockColumn}: + *
        + *
      • The generator lets you specify a class to generate the + * sample data. Rules for the class name is that it can either contain + * a full package path, or just a class name. If just a class name, the + * class is assumed to reside in this package. For example, to generate + * an ISO date into a string, use DateGen. Additional generators + * can (and should) be added as the need arises.
        • + *
      • The repeat attribute lets you create a very wide row by + * repeating a column the specified number of times. Actual column names + * have a numeric suffix. For example, if the base name is "blue" and + * is repeated twice, actual columns are "blue1" and "blue2".
        • + *
      + * When used in SQL, use the mock name space as follows: + * 
      
+ * SELECT id_i, name_s50 FROM `mock`.`employee_500`;
+ *
      + * Both the column names and table names encode information that specifies + * what data to generate. + *

      + * Columns are of the form name_typelength?. + *

        + *
      • The name is anything you want ("id" and "name" in the example.)
        • + *
      • The underscore is required to separate the type from the name.
        • + *
      • The type is one of "i" (integer), "d" (double) or "s" (string). + * Other types can be added as needed: n (decimal number), l (long), etc.
        • + *
      • The length is optional and is used only for string (VARCHAR) + * columns. The default string length is 10.
        • + *
      • Columns do not yet support nulls. When they do, the encoding will + * be "_npercent" where the percent specifies the percent of rows + * that should contain null values in this column. + *
      • The column is known to SQL as its full name, that is "id_i" or + * "name_s50".
        • + *
      + *

      + * Tables are of the form name_rowsunit? where: + *

        + *
      • The name is anything you want. ("employee" in the example.)
        • + *
      • The underscore is required to separate the row count from the name.
        • + *
      • The row count specifies the number of rows to return.
        • + *
      • The count unit can be none, K (multiply count by 1000) or M + * (multiply row count by one million), case insensitive.
        • + *
      • Another field (not yet implemented) might specify the split count.
        • + *
      + *

      Enhanced Mode with Definition File

      + * You can reference a mock data definition file directly from SQL as follows: + * SELECT * FROM `mock`.`your_defn_file.json` + *

      Data Generators

      + * The classic mode uses data generators built into each vector to generate + * the sample data. These generators use a very simple black/white alternating + * series of two values. Simple, but limited. The enhanced mode allows custom + * data generators. Unfortunately, this requires a separate generator class for + * each data type. As a result, we presently support just a few key data types. + * On the other hand, the custom generators do allow tests to specify a custom + * generator class to generate the kind of data needed for that test. + *

      + * All data generators implement the {@link FieldGen} interface, and must have + * a non-argument constructor to allow dynamic instantiation. The mock data + * source either picks a default generator (if no generator is provided) + * or uses the custom generator specified in generator. Generators + * are independent (though one could, perhaps, write generators that correlate + * field values.) + */ +package org.apache.drill.exec.store.mock; \ No newline at end of file diff --git a/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/Metadata.java b/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/Metadata.java index d7d31e52157..d85d6f1e396 100644 --- a/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/Metadata.java +++ b/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/Metadata.java @@ -22,13 +22,17 @@ import java.util.Arrays;

Key components + * include: + *

        + *
      • {@link FixtureBuilder}: Builder pattern to create an embedded Drillbit, + * or cluster of Drillbits, using a specified set of configuration, session + * and system options.
        • + *
      • {@link ClusterFixture}: The cluster created by the builder.
        • + *
      • {@link ClientFixture}: A facade to the Drill client that provides + * convenience methods for setting session options, running queries and + * so on. A client is associated with a cluster. If tests desire, multiple + * clients can be created for a single cluster, though most need just one + * client. A builder exists for clients, but most tests get the client + * directly from the cluster.
        • + *
      • {@link QueryBuilder}: a builder pattern for constructing and + * running any form of query (SQL, logical or physical) and running the + * query in a wide variety of ways (just count the rows, return the + * results as a list, run using a listener, etc.)
        • + *
      • {@link QueryBuilder.QuerySummary QuerySummary}: a summary of a + * query returned from running the query. Contains the query ID, the + * row count, the batch count and elapsed run time.
        • + *
      • {@link ProfileParser}: A simple tool to load a query profile and + * provide access to the profile structure. Also prints the key parts of + * the profile for diagnostic purposes.
        • + *
      • {@link LogFixture}: Allows per-test changes to log settings to, + * say, send a particular logger to the console for easier debugging, or + * to suppress logging of a deliberately created failure.
        • + *
      + *

      Usage

      + * A typical test using this framework looks like this: + * 
      +  {@literal @}Test

Elsewhere in + * Drill we call this a "record batch", but that term has been overloaded to + * mean the runtime implementation of an operator... + *

      + * A row set encapsulates a set of vectors and provides access to Drill's + * various "views" of vectors: {@link VectorContainer}, + * {@link VectorAccessible}, etc. + *

      + * A row set is defined by a {@link RowSetSchema}. For testing purposes, a row + * set has a fixed schema; we don't allow changing the set of vectors + * dynamically. + *

      + * The row set also provides a simple way to write and read records using the + * {@link RowSetWriter} and {@link RowSetReader} interfaces. As per Drill + * conventions, a row set can be written (once), read many times, and finally + * cleared. + *

      + * Drill provides a large number of vector (data) types. Each requires a + * type-specific way to set data. The row set writer uses a {@link ColumnWriter} + * to set each value in a way unique to the specific data type. Similarly, the + * row set reader provides a {@link ColumnReader} interface. In both cases, + * columns can be accessed by index number (as defined in the schema) or + * by name. + *

      + * A row set follows a schema. The schema starts as a + * {@link BatchSchema}, but is parsed and restructured into a variety of + * forms. In the original form, maps contain their value vectors. In the + * flattened form, all vectors for all maps (and the top-level tuple) are + * collected into a single structure. Since this structure is for testing, + * this somewhat-static structure works just file; we don't need the added + * complexity that comes from building the schema and data dynamically. + *

      + * Putting this all together, the typical life-cycle flow is: + *

        + *
      • Define the schema using {@link RowSetSchema#builder()}.
        • + *
      • Create the row set from the schema.
        • + *
      • Populate the row set using a writer from {@link #writer(int)}.
        • + *
      • Optionally add a selection vector: {@link #makeSv2()}.
        • + *
      • Process the vector container using the code under test.
        • + *
      • Retrieve the results using a reader from {@link #reader()}.
        • + *
      • Dispose of vector memory with {@link #clear()}.

+/**
+ * Provides a set of tools to work with row sets when creating operator
+ * and "sub-operator" unit tests. A row set is a batch of Drill vectors,
+ * often called a "record batch." However, a record batch, in Drill, means
+ * not just the data, but also an operator on that data. The classes
+ * here work with the data itself, and can be used to test implementations
+ * of things such as code generated classes and so on.
+ * 
      
+ * The classes include tools for reading and writing row sets, comparing
+ * actual and expected results, and so on.
+ * 
      
+ * Drill defines a variety of record batch semantics, modeled here as
+ * distinct row set classes:
+ * 
      
+ * 
      RowSet
      
+ * 
      The abstract definition of a row set that defines operations available
+ * on all row sets.
      
+ * 
      SingleRowSet (abstract)
      
+ * 
      Represents a row set that contains a single record batch (the typical
+ * case.
      
+ * 
      DirectRowSet
      
+ * 
      A read-only single row set without a selection vector.
      
+ * 
      IndirectRowSet
      
+ * 
      A read-only, single row set with an SV2. Note that the SV2 itself is
+ * writable (such as for sorting.)
      
+ * 
      ExtendibleRowSet
      
+ * 
      A write-only, single row set used to create a new row set. Because of
+ * the way Drill sets row counts, an extendible row set cannot be read; instead
+ * at the completion of the write the extendible row set becomes a direct or
+ * indirect row set.
      
+ * 
      HyperRowSet
      
+ * 
      A read-only row set made up of a collection of record batches, indexed via an
+ * SV4. As with the SV2, the SV4 itself is writable.
+ * 
      
+ * This package contains a number of helper classes:
+ * 
      
+ * 
      RowSetWriter
      
+ * 
      Writes data into an extendible row set.
      
+ * 
      RowSetReader
      
+ * 
      Reads data from any but an extendible row set.
      
+ * 
      RowSetBuilder
      
+ * 
      Creates and populates a row set in a fluent builder style.
      
+ * 
      RowSetPrinter
      
+ * 
      Prints a row set to stdout in a CSV-like form for easy debugging.
      
+ * 
      RowSetComparision
      
+ * 
      Used in tests to compare an "actual" row set against an "expected"
+ * row set. Does a complete check of row counts, types and values. If values
+ * are arrays (repeated), does a check of the entire array. Uses JUnit assertions
+ * to report comparison failures.
      
+ * 
      SchemaBuilder
      
+ * 
      Drill normally writes data to vectors, then "discovers" the row set schema based on the
+ * data written. For tests, it is usually far easier to simply declare a schema, then
+ * read and write data according to that schema. The schema builder provides a simple,
+ * fluent tool to create a row set schema. That schema then drives the row set readers
+ * and writers, the row set printer and the row set comparison.
      
+ *

+/**
+ * Basic accessors for most Drill vector types and modes. These are bare-bones
+ * accessors: they do only the most rudimentary type conversions. For all,
+ * there is only one way to get/set values; they don't convert from, say,
+ * a double to an int or visa-versa.
+ * 
      
+ * Writers work only with single vectors. Readers work with either single
+ * vectors or a "hyper vector": a collection of vectors indexed together.
+ * The details are hidden behind the {@link RowIndex} interface. If the reader
+ * accesses a single vector, then the mutator is cached at bind time. However,
+ * if the reader works with a hyper vector, then the vector is null at bind
+ * time and must be retrieved for each row (since the vector differs row-by-
+ * row.)

+/**
+ * Provides a light-weight, simplified set of column readers and writers that
+ * can be plugged into a variety of row-level readers and writers. The classes
+ * and interfaces here form a framework for accessing rows and columns, but do
+ * not provide the code to build accessors for a given row batch. This code is
+ * meant to be generic, but the first (and, thus far, only) use is with the test
+ * framework for the java-exec project. That one implementation is specific to
+ * unit tests, but the accessor framework could easily be used for other
+ * purposes as well.
+ * 
      
+ * Drill provides a set of column readers and writers. Compared to those, this
+ * set:
+ * 
        
+ * 
      • Works with all Drill data types. The other set works only with repeated
+ * and nullable types.
        • 
+ * 
      • Is a generic interface. The other set is bound tightly to the
+ * {@link ScanBatch} class.
        • 
+ * 
      • Uses generic types such as getInt() for most numeric types. The
+ * other set has accessors specific to each of the ~30 data types which Drill
+ * supports.
        • 
+ * 
      
+ * The key difference is that this set is designed for developer ease-of-use, a
+ * primary requirement for unit tests. The other set is designed to be used in
+ * machine-generated or write-once code and so can be much more complex.
+ * 
      
+ * That is, the accessors here are optimized for test code: they trade
+ * convenience for a slight decrease in speed (the performance hit comes from
+ * the extra level of indirection which hides the complex, type-specific code
+ * otherwise required.)
+ * 
      
+ * {@link ColumnReader} and {@link ColumnWriter} are the core abstractions: they
+ * provide simplified access to the myriad of Drill column types via a
+ * simplified, uniform API. {@link TupleReader} and {@link TupleWriter} provide
+ * a simplified API to rows or maps (both of which are tuples in Drill.)
+ * {@link AccessorUtilities} provides a number of data conversion tools.
+ * 
      
+ * Overview of the code structure:
+ * 
      
+ * 
      TupleWriter, TupleReader
      
+ * 
      In relational terms, a tuple is an ordered collection of values, where
+ * the meaning of the order is provided by a schema (usually a name/type pair.)
+ * It turns out that Drill rows and maps are both tuples. The tuple classes
+ * provide the means to work with a tuple: get the schema, get a column by name
+ * or by position. Note that Drill code normally references columns by name.
+ * But, doing so is slower than access by position (index). To provide efficient
+ * code, the tuple classes assume that the implementation imposes a column
+ * ordering which can be exposed via the indexes.
      
+ * 
      ColumnAccessor
      
+ * 
      A generic base class for column readers and writers that provides the
+ * column data type.
      
+ * 
      ColumnWriter, ColumnReader
      
+ * 
      A uniform interface implemented for each column type ("major type" in
+ * Drill terminology). The scalar types: Nullable (Drill optional) and
+ * non-nullable (Drill required) fields use the same interface. Arrays (Drill
+ * repeated) are special. To handle the array aspect, even array fields use the
+ * same interface, but the getArray method returns another layer of
+ * accessor (writer or reader) specific for arrays.
+ * 
      
+ * Both the column reader and writer use a reduced set of data types to access
+ * values. Drill provides about 38 different types, but they can be mapped to a
+ * smaller set for programmatic access. For example, the signed byte, short,
+ * int; and the unsigned 8-bit, and 16-bit values can all be mapped to ints for
+ * get/set. The result is a much simpler set of get/set methods compared to the
+ * underlying set of vector types.
+ * 
      ArrayWriter, ArrayReader
+ * 
      
+ * 
      The interface for the array accessors as described above. Of particular
+ * note is the difference in the form of the methods. The writer has only a
+ * setInt() method, no index. The methods assume write-only, write-once
+ * semantics: each set adds a new value. The reader, by contrast has a
+ * getInt(int index) method: read access is random.
+ * 
      ScalarWriter
      
+ * 
      Because of the form of the array writer, both the array writer and
+ * column writer have the same method signatures. To avoid repeating these
+ * methods, they are factored out into the common ScalarWriter
+ * interface.
      
+ * 
      ColumnAccessors (templates)
      
+ * 
      The Freemarker-based template used to generate the actual accessor
+ * implementations.
      
+ * 
      ColumnAccessors (accessors)
      
+ * 
      The generated accessors: one for each combination of write/read, data
+ * (minor) type and cardinality (data model).
+ * 
      
+ * 
      RowIndex
      
+ * 
      This nested class binds the accessor to the current row position for the
+ * entire record batch. That is, you don't ask for the value of column a for row
+ * 5, then the value of column b for row 5, etc. as with the "raw" vectors.
+ * Instead, the implementation sets the row position (with, say an interator.)
+ * Then, all columns implicitly return values for the current row.
+ * 
      
+ * Different implementations of the row index handle the case of no selection
+ * vector, a selection vector 2, or a selection vector 4.
      
+ * 
      VectorAccessor
      
+ * 
      The readers can work with single batches or "hyper"
+ * batches. A hyper batch occurs in operators such as sort where an operator
+ * references a collection of batches as if they were one huge batch. In this
+ * case, each column consists of a "stack" of vectors. The vector accessor picks
+ * out one vector from the stack for each row. Vector accessors are used only
+ * for hyper batches; single batches work directly with the corresponding
+ * vector.
+ * 
      
+ * You can think of the (row index + vector accessor, column index) as forming a
+ * coordinate pair. The row index provides the y index (vertical position along
+ * the rows.) The vector accessor maps the row position to a vector when needed.
+ * The column index picks out the x coordinate (horizontal position along the
+ * columns.)
+ *
