Martijn Visser commented on FLINK-31820:
----------------------------------------
[~complone] I've done a quick Google search for "mysql subtable" and "postgres
sybtable" but neither result in documentation from these providers. You mention
that these are common, but given that they aren't documented on their pages,
I'm not sure they are. Before creating a PR, I think it's important that we
reach consensus that this is a) something that we want and b) how we want to
introduce this in Flink.
> Support data source sub-database and sub-table
> ----------------------------------------------

> Key: FLINK-31820
> URL: https://issues.apache.org/jira/browse/FLINK-31820
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / JDBC
> Reporter: xingyuan cheng
> Priority: Major
> Labels: pull-request-available
>
> At present, apache/flink-connector-jdbc does not support sub-database and
> table sub-database. Now three commonly used databases Mysql, Postgres and
> Oracle support sub-database and sub-table
>
> Taking oracle as an example, users only need to configure the following
> format to use
>
> {code:java}
> create table oracle_source (
> EMPLOYEE_ID BIGINT,
> START_DATE TIMESTAMP,
> END_DATE TIMESTAMP,
> JOB_ID VARCHAR,
> DEPARTMENT_ID VARCHAR
> ) with (
> type = 'oracle',
> url =
> 'jdbc:oracle:thin:@//localhost:3306/order_([0-9]{1,}),jdbc:oracle:thin:@//localhost:3306/order_([0-9]{1,})',
> userName = 'userName',
> password = 'password',
> dbName = 'hr',
> tableName = 'job_history',
> timeField = 'START_DATE',
> startTime = '2007-1-1 00:00:00'
> ); {code}
> In the above code, the dbName attribute corresponds to the schema-name
> attribute in oracle or postgres, and the mysql database needs to manually
> specify the dbName
>
> At the same time, I am also developing the CDAS whole database
> synchronization syntax for the company, and the data source supports
> sub-database and table as part of it. Add unit tests. For now, please keep
> this PR in draft status.
