This module provide column meta decoder for binlog protocol.
There're certain type won't appear in binlog event, and some types are compressed into mySQLTypeString
, please take python version as a reference: https://github.com/noplay/python-mysql-replication
You will not directly meet following FieldType
namely:
- mySQLTypeDecimal
- mySQLTypeNewdate
- mySQLTypeEnum
- mySQLTypeSet
- mySQLTypeTinyBlob
- mySQLTypeMediumBlOb
- mySQLTypeLongBlob
