> Key: KAFKA-7024
> URL: https://issues.apache.org/jira/browse/KAFKA-7024
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Abhishek Agarwal
> Priority: Minor
> Labels: user-experience
>
> After enabling rocksDB logging, We continually see these errors in kafka
> stream logs, everytime a new window segment is created
> ```
> Error when reading <rocksdb-directory-path>
> ```
> While its not a problem in itself, since rocksDB internally will create the
> directory but It will do so only after logging the above error. It would
> avoid unnecessary logging if the segment directory can be created in advance.
> Right now, only the parent directories are created for a rocksDB segment.
> Logging is more prominent when there are many partitions and segment size is
> smaller (minute or two).
