----------------------------------
Summary: Transactional Producer could add partitions by batch at
the end
Key: KAFKA-9860
URL: https://issues.apache.org/jira/browse/KAFKA-9860
Project: Kafka
Issue Type: Improvement
Reporter: Boyang Chen
Assignee: Boyang Chen
As of today, the Producer transaction manager bookkeeps the partitions involved
with current transaction. Each time it sees a new partition, it will try to
send a request to add all the involved partitions to the broker, which results
in multiple requests. If we could batch the work by the end of the transaction,
we save unnecessary round trips.
