Hi, Yifan.
Unfortunately, IIUC, we could get the key and value type only by reading
related sql codes currently.
I think it's useful if we could support SQL semantics for the Processor
API, but it indeed will take lots of effort.

Hi Hangxiang,
I still have one question about this problem, when using datastream api I
know the key and value type I use in state because I
defined ValueStateDescriptor, but how can I get the ValueStateDescriptor in
flinksql?
Thanks,
Yifan

Hi Hangxiang,
We are using flink 1.14, the state backend is EmbeddedRocksDBStateBackend ,
and the Checkpoint Storage is filesystem.
This is the checkpoint configuration from our running jobs

Hi, Yifan.
Which flink version are you using ?
You are using filesystem instead of rocksdb so that your checkpoint size
may not be incremental IIUC.

Hi, Yifan.
If you enable the debug level log, you could see the log like 'Generated
hash xxx for node xxx'. I haven't found other ways to find the operator id
of SQL jobs, maybe I missed something, or we should export this info more
directly.
Unfortunately, there is no default state name for an ope
Hi Hangxiang,
Thanks for your answer! We are using RocksDB state backend, and the
incremental checkpoint is enabled, and it is the incremental size keeps
increasing. We didn't add any custom checkpoint configuration in flink sql
jobs, where can I see the log of
StreamGraphHasherV2.generateDetermin
Hi Shammon,
We are using RocksDB,and the configuration is below:
execution.checkpointing.externalized-checkpoint-retention:
RETAIN_ON_CANCELLATION
execution.checkpointing.max-concurrent-checkpoints: 1
execution.checkpointing.min-pause: 0
execution.checkpointing.mode: EXACTLY_ONCE
execution.checkpo
Hi, Yifan
Flink SQL & Table API currently doesn't support reading the state directly.
Best,
Ron

Hi Yifan,
Besides reading job state, I would like to know what statebackend are you
using? Can you give the configurations about state and checkpoint for your
job? Maybe you can check these configuration items to confirm if they are
correct first.

Hi, Yifan.
I think the document[1] means to let us convert the DataStream to the
Table[2]. Then we could handle the state with the Table API & SQL.

Hang

Hi, Yifan.
Unfortunately, The State Processor API only supports Datastream currently.
But you still could use it to read your SQL job state.
The most difficult thing is that you have to get the operator id which you
could get from the log of StreamGraphHasherV2.generateDeterministicHash and
state n
Hi Yifan,
AFAIK, if you want to query a job’s state from outside Flink, you can use
Queryable State[1].
Hope this helps.
