Jason Gustafson created KAFKA-7570: -------------------------------------- Summary: Make internal offsets/transaction schemas forward compatible Key: KAFKA-7570 URL: https://issues.apache.org/jira/browse/KAFKA-7570 Project: Kafka Issue Type: Improvement Reporter: Jason Gustafson
Currently changes to the data stored in the internal topics (__consumer_offsets and __transaction_state) are not forward compatible. This means that once users have upgraded to a Kafka version which includes a bumped schema, then it is no longer possible to downgrade. The changes to these schemas tend to be incremental, so we should consider options that at least allow new fields to be added without breaking downgrades. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
