YangXuan reopened HUDI-3103:
----------------------------
> Enable MultiTableDeltaStreamer to update a single target table from multiple
> source tables.
> -------------------------------------------------------------------------------------------
>
> Key: HUDI-3103
> URL: https://issues.apache.org/jira/browse/HUDI-3103
> Project: Apache Hudi
> Issue Type: New Feature
> Components: DeltaStreamer
> Reporter: YangXuan
> Priority: Major
> Labels: pull-request-available
>
> It is very appropriate when MultiTableDeltaStreamer completes the business of
> updating table a' by table a and updating table b' by table b. Because
> MultiTableDeltaStreamer will start two threads, one to update table a', and
> the other to update table b'. If the current service scenario is that table a
> and table b update table c at the same time, MultiTableDeltaStreamer may
> encounter write conflict and cannot complete the service.
