Hi,

I am learning Stateful function and saw below:

"In addition to the Apache Flink processes, a full deployment requires
ZooKeeper <https://zookeeper.apache.org/> (for master failover
<https://ci.apache.org/projects/flink/flink-docs-stable/ops/jobmanager_high_availability.html>)
and bulk storage (S3, HDFS, NAS, GCS, Azure Blob Store, etc.) to store
Flinkā€™s checkpoints
<https://ci.apache.org/projects/flink/flink-docs-master/concepts/stateful-stream-processing.html#checkpointing>.
In turn, the deployment requires no database, and Flink processes do not
require persistent volumes."

Does this mean stateful function does not support rocksdb (and incremental
checkpoint, local task recovery)? Will it be an issue for large state (e.g.
200GB) applications? Thanks for clarifying.


Thanks
Lian
