Hello friendly Flink community! I'm curious if anyone has operational experience with jobs that store ListState where occasionally, due to skew, some small number of lists stored in ListState (stored in RocksDB) will have millions of elements. Here are the stats:
* millions of keys * p95 size of list in ListState is ~2. * some small number of keys (less than 100) may have lists whose size is on the order of tens of thousands and up to millions. * state is stored in RocksDB Are there any known issues or limitations with storing or fetching that much list state out of RocksDB? I realize fetching from RocksDB and deserializing will be costly when hitting a key with a list of a million elements, but is there anything else we should consider? Thanks! Best, Aaron Levin
