Description

Support insert part of columns of arctic table with flink in streaming mode

Use case/motivation

Arctic only support insert all table columns with flink in streaming mode now. If souce table DOES NOT have all columns which sink table need, user must join multiple source table, which will cause a big state problem. If Arctic support insert part of columns, user can start multiple flink job and each job insert part of columns(including join column) into arctic table to avoid problem mentioned above.

Describe the solution

• Support insert part of columns of arctic table with flink in streaming mode
• Merge all columns together when optiming
