?????? Where will the state be stored in the taskmanager when using rocksdbstatebend??

Hi,Alexander


When Flink job deployed on Native k8s, taskmanager is a Pod.The data directory 
size of a single container is limited in our company.Are there any idea to deal 
with this ?




Best,

Make sure to use a local SSD disk (not NFS/EBS).

The EmbeddedRocksDBStateBackend holds in-flight data in

Which path does local data directories store RocksDB database in 
TaskManager&nbsp;point to in operating system?
If the job state is very large, I think I should &nbsp;take some measures to 
deal with it.(mount a volume for local data directories store RocksDB database 
etc...)


thx.
