Description

Currently consumer supports offset order to receive messages.There are some cases where commit order is very important.For example assume case where PostgreSQL-14  randomly streams multiple in-progress large transactions to some intermediate client which starts transactional producer instances for multiple in-progress transactions,using this producer instances client pushes data to kafka. Now consumer should strictly read messages based on commit order.
