Hello,

We are using RocksDB as the backend state.

At first we didn't enable the checkpoints mechanism.

We observed the following behaviour and we are wondering why ?

When using the rocksDB without checkpoint the performance was very extremely bad.

And when we enabled the checkpoint the performance was improved by a factor of 10.

Could you please explain if this behaviour is expected ?

Could you please explain why enabling the checkpoint significantly improves the performance ?

BR,

Nick
