The concurrency of this library is easier to handle than Sarama. Notably, it is more compatible with the new model of "almost share nothing" we use for the inlet and the outlet. The lock for workers in outlet is removed. We can now use sync.Pool to allocate slice of bytes in inlet. It may also be more performant. In the future, we may want to commit only when pushing data to ClickHouse. However, this does not seem easy when there is a rebalance. In case of rebalance, we need to do something when a partition is revoked to avoid duplicating data. For example, we could flush the current batch to ClickHouse. Have a look at the `example/mark_offsets/main.go` file in franz-go repository for a possible approach. In the meantime, we rely on autocommit. Another contender could be https://github.com/segmentio/kafka-go. Also see https://github.com/twmb/franz-go/pull/1064.
