WL#4618 RBR: extended table metadata in the binary log
This patch extends Table Map Event. It appends some new fields for
more metadata. The new metadata includes:
- Signedness of Numberic Columns
- Character Set of Character Columns and Binary Columns
- Column Name
- String Value of SET Columns
- String Value of ENUM Columns
- Primary Key
- Character Set of SET Columns and ENUM Columns
- Geometry Type
Some of them are optional, the patch introduces a GLOBAL system
variable to control it. It is binlog_row_metadata.
- Scope: GLOBAL
- Dynamic: Yes
- Type: ENUM
- Values: {NO_LOG, MINIMAL, FULL}
- Default: NO_LOG
Only Signedness, character set and geometry type are logged if it is MINIMAL.
Otherwise all of them are logged.
Also add a binlog_type_info() to field, So that we can have extract
relevant binlog info from field.
