sivabalan narayanan updated HUDI-2318:
--------------------------------------
Description:
Currently multi-table deltastreamer supports COW and only for run once mode. We
need to enhance lot more and make it usable for all different scenarios.
There are asks from the community on this. Typical use-cases:
I have 1000+ tables and I wish to ingest all of them into hudi parallely. I
don't want to use 1000+ delta streamer instances as I have to allot resources
for every deltastreamer instance.
Requirements
* Add MOR support to Multi-table deltastreamer
* Add continuous mode support to multi-table ds.
* Add support to sync concurrently across diff tables. As of now, each table
is synced serially which may not work out well for 1000+ tables. We may not
want to sync 1000+ tables concurrently. But using a thread-pool, we can achieve
some level of concurrency.
