@s-m-sufyian thanks for volunteering to take this issue! The idea was to use Kafka's built-in offset storage API to store Liiklus' offsets, so that the deployment can be simplified to "just Kafka" for those who are ready to store the offsets in Kafka's format.

It will require implementing PositionsStorage. Have a look at RedisPositionsStorage for some inspiration.

Feel free to ask any question you may have 👍
