> The problem is: Mysql jdbc will return java type `BigInteger` when get `bigint unsigned` in database, check out [there](https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-type-conversions.html). But JdbcSource informationMapping Map convert it to `BIG_INT_TYPE_INFO` which flink not support, check out : [Fix reading BIGINT UNSIGNED type field not work in JDBC](https://issues.apache.org/jira/browse/FLINK-17657?jql=project%20%3D%20FLINK%20AND%20text%20~%20%22sql%20biginter%22#). Also `bigint unsigned` is only in Mysql series database. > > #### Solve Plan > 1. Override JdbcInputFormat so it can hand with `bigint unsigned` as string. > 2. Support PostgreSQL's datatype. > 3. Separate JdbcSource informationMapping for different databases learn a lot. -- This is an automated message from the Apache Git Service.
