Getting/Setting consumer state

[Matan Rosenberg (matan129)]

Hi,

One of my apps uses Parallel Consumer 0.5.2.8.
It consumes messages from Kafka with consumer group A, and maintains some data structure on-disk.

This data structure (well - a collection of files) is periodically backed up to remote storage.

I have a use case in which a different service (with consumer group B), needs to download the backup and start ingesting from the point that service A left it.

Q: Is there a way to get (and set?) the current position & state of the consumer?

Currently, I get the committed offsets per partition and use it as an approximation, but it's not granular enough.

Thanks!
