[jira] [Created] (FLINK-31433) Make SchemaChange serializable

Caizhi Weng created FLINK-31433:
-----------------------------------

             Summary: Make SchemaChange serializable
                 Key: FLINK-31433
                 URL: https://issues.apache.org/jira/browse/FLINK-31433
             Project: Flink
          Issue Type: Sub-task
          Components: Table Store
    Affects Versions: table-store-0.4.0
            Reporter: Caizhi Weng
            Assignee: Caizhi Weng
             Fix For: table-store-0.4.0


To avoid concurrent changes to table schema, CDC sinks for Flink Table Store should send all \{{SchemaChange}} to a special process function. This process function only has 1 parallelism and it is dedicated for schema changes.

 

To pass \{{SchemaChange}} through network, \{{SchemaChange}} must be serializable.
