…anmu_no_key_error (#1462)" In version 1.0.4, we will discard "MANDATORY_TIANMU" and "NO_KEY_ERROR" in (sql_mode) Specifies whether to enable mandatory Tianmu engine in table. if yes ,set tianmu_mandatory to ON, otherwise set the variable to OFF. Specifies whether to to directly skip DDL statements that are not supported by the SQL layer, instead of reporting errors. if yes ,set tianmu_no_key_error to ON, otherwise set the variable to OFF.
…primary/secondary synchronization if UUIDs are used as the primary key(#1464) Cause of the problem: When performing a primary key scan under the master slave, "ha_tianmu:: position()" is called first to obtain the primary key value from the "record", However, in this scenario, after calling the "key_copy()" function, the "record" will be cleared, resulting in the subsequent "GetKeys()" obtaining a null primary key value. Solution: Because the value "handler->ref" is not used in the future, you can simply delete the call to "key_copy()".

…on issues(#366) Cause of the problem: 1. For multiple versions, Tianmu needs to first copy an original pack when performing DML operations, Modify the copied package and use append write or overwrite write after modification (If there is invalid space in the DATA file that can be written to the current pack, use overwrite write, otherwise use append write) to write to the file, After the latest package is written to a file, the latest version chain will point to the address that was last written. There is a problem with the current (TianmuAttr:: LoadData) logic. Every time you call (TianmuAttr:: LoadData), Will write data to disk, If there are multiple rows written in a transaction, there will be multiple copies of data, "Because the current transaction has not been committed, the space for previous repeated writes has not been released, so the logic of overwriting writes will not be reached.", "I only follow the logic of additional writing, which is the fundamental reason for the skyrocketing space.". If you encounter a particularly large multiline write transaction, it will lead to a space explosion. Moreover, disk IO is performed once per load line, which can also lead to degraded insert performance. Solution: To optimize the logic of (TianmuAttr:: LoadData), it is necessary to determine whether the data in the pack is full before saving changes, Is whether to reach 65536 lines, and if so, write again, If it cannot be reached, it is necessary to write again in the commit phase.

To support `update ignore` statement. The logic of uniqueness check is re-implemented.
Cause: in the function ParsingStrategy::ParseResult ParsingStrategy::GetOneRow field->val_str(str) cannot distinguish 0 and NULL value. Solution: Check whether field's default value is NULL.

In multi-thread aggregation, ExpressionColumn will occur double free due to without protection. Thread A will do ValueOrNull::operator ==, but in thread B, it will try to free it. Therefore, it leads to instance crash.
…_max #1564 [summary] 1. static_cast<int64_t>(18446744073709551601) = -15 2. Item will set 18446744073709551601 with unsigned flag, but in tianmu transform to ValueOrNot, the value will be set to `-15`. 3. add `unsigned flag` in value_or_null & TianmuNum & tianmu expr.
…ision loss problem (#1173) When converting TIME/DATETIME to ulonglong numeric, tianmu engine does not take the TIME_to_ulonglong_time_round process. This causes the results different from innodb. Furthermore, when we close the tianmu_insert_delayed parameter and execute an insert SQL, the TIME/DATETIME/TIMESTAMP type's data will loss precision due to incomplete attribute copying.

…t cannot be recorded(#1876) 1. Actually, tianmu uses its own code to handle load which lacks support of row format of binlog 2. When tianmu parsing rows, write table map event first 3. Once tianmu constructs a row, just add it to the rows log event, when parsing is done, the rows log event will also be ready, then write it to the binlog
