Hi,
I'm recently trying to use State Processor API, but I have some questions
during the development.
1. Does `OperatorTransformation#bootstrapWith` support scala api `DataSet`?
I tried, but IDE showed that it will have compile error on that line.
2. It seems that creating RocksDBStateBackend should provide a checkpoint
path, but by using
`Savepoint#create` we didn't read or write anything from or into this
checkpoint path. This is for
constructing RocksDBStateBackend object only. Am I right?
```
Savepoint
.create(new RocksDBStateBackend(checkpointPath), maxParallelism)
```
Thanks in advance.
Best,
Tony Wei
