Anish Shrigondekar updated SPARK-43311:
---------------------------------------
Description:
Today when RocksDB is used as a State Store provider, memory usage when writing
using writeBatch is not capped. Also, a related issue is that the state store
coordinator can create multiple RocksDB instances on a single node without
enforcing a global limit on native memory usage. Due to these issues we could
run into OOM issues and task failures.
We are looking to improve this behavior by doing a series of improvements such
as:
* remove writeBatch and use native RocksDB operations
* use writeBufferManager to manage global limit for all instances on a single
node and accounting memtable + filter/index blocks usage as part of block
cacheWith these changes we will be avoiding OOM issues around RocksDB native
memory usage.
