-----------------------------------
Summary: Support migrating states between different instances of
TableWriteImpl and AbstractFileStoreWrite
Key: FLINK-31430
URL: https://issues.apache.org/jira/browse/FLINK-31430
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
Currently {{Table}} and {{TableWrite}} in Flink Table Store have a fixed
schema. However to consume schema changes, Flink Table Store CDC sinks should
have the ability to change its schema during a streaming job.
This require us to pause and store the states of a {{TableWrite}}, then create
a {{TableWrite}} with newer schema and recover the states in the new
{{TableWrite}}.
