 # presto-connector
-Pravega connector for Presto
+Pravega Presto connector
+
+Presto is a distributed SQL query engine for big data. Presto uses connectors to query storage from different storage sources. This repository contains the code for a connector (the Pravega Presto connector) to query storage from Pravega streams. To learn more about PrestoDB, visit https://prestodb.io
+
+Pravega is an open source distributed storage service implementing Streams. It offers Stream as the main primitive for the foundation of reliable storage systems: a high-performance, durable, elastic, and unlimited append-only byte stream with strict ordering and consistency.  To learn more about Pravega, visit https://pravega.io
+
+See the [User Manual](https://prestodb.github.io/docs/current/) for Presto deployment instructions and end user documentation.
+
+## Requirements
+
+To build and run the Pravega Presto connector, you must meet the following requirements:
+
+* Linux 
+* Java 8 Update 151 or higher (8u151+), 64-bit. Both Oracle JDK and OpenJDK are supported.
+* Gradle 6.5.1+ (for building)
+* Python 2.7+ (for running with the launcher script)
+* Pravega version 0.9.0 or higher
+* Pravega Schema Registry version 0.2.0 or higher
+
+## Building Presto
+
+Pravega Presto connector is a standard Gradle project. Simply run the following command from the project root directory:
+
+    ./gradlew clean build
+
+On the first build, Gradle will download all the dependencies from various locations of the internet and cache them in the local repository (`~/.gradle / caches `), which can take a considerable amount of time.  Subsequent builds will be faster.  
+
+Pravega Presto connector has a set of unit tests that can take several minutes to run. You can run the tests using this command:
+
+    ./gradlew test
+
+## Running Presto
+
+The plugin file that gets created during the build process is: ./build/distributions/pravega-<VERSION>.tar.gz.  This file can be untar'd in the /usr/lib/presto/lib/plugins directory of a running Presto installation. Like all Presto connectors, the Pravega Presto connector uses a properties files to point to the storage provider (e.g. Pravega controller).  Create a properties file similar to below, but replace the # characters with the appropriate IP address of the Pravega Controller and the Pravega Schema Registry server of your configuration.
+
+    [root@lrmk226 ~]# cat /etc/presto/catalog/pravega.properties
+    connector.name=pravega
+    pravega.controller=tcp://##.###.###.###:9090
+    pravega.schema-registry=http://##.###.###.###:9092
+
+## Running Presto in your IDE
+
+After building Presto for the first time, you can load the project into your IDE and run the server in your IDE. We recommend using [IntelliJ IDEA](http://www.jetbrains.com/idea/). Because Pravega Presto connectoris a standard Gradle project, you can import it into your IDE. In IntelliJ, choose Import Project from the Quick Start box and point it to the root of the source tree.  IntelliJ will identify the *.gradle files and prompt you to confirm.
+
+After opening the project in IntelliJ, double check that the Java SDK is properly configured for the project:
+
+* Open the File menu and select Project Structure
+* In the SDKs section, ensure that a 1.8 JDK is selected (create one if none exist)
+* In the Project section, ensure the Project language level is set to 8.0 as Presto makes use of several Java 8 language features
+
+Use the following options to create a run configuration that runs the Presto server using the Pravega Presto connector:
+
+* Main Class: 'com.facebook.presto.server.PrestoServer'
+* VM Options: '-ea -XX:+UseG1GC -XX:G1HeapRegionSize=32M -XX:+UseGCOverheadLimit -XX:+ExplicitGCInvokesConcurrent -Xmx2G -Dconfig=etc/config.properties -Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true -Dlog.levels-file=etc/log.properties'
+* Working directory: '/root/presto'
+* Use classpath of module: 'pravega.main'
+
+The working directory should be manually created and set to where the configuration properties files are located on your host.

+
+Create the pravega.properties file as previously described.
+
+## Schema Definitions
+
+Currently, you must manually create schema definitions using a JSON file. In future releases, the 'CREATE TABLE' Presto command will be available.
