Jason Gustafson created KAFKA-10702: ---------------------------------------
Summary: Slow replication of empty transactions Key: KAFKA-10702 URL: https://issues.apache.org/jira/browse/KAFKA-10702 Project: Kafka Issue Type: Bug Reporter: Jason Gustafson Assignee: Jason Gustafson We hit a case in which we had to re-replicate a compacted topic from the beginning of the log. Some portions of the log consisted mostly of transaction markers, which were extremely slow to replicate. The problem is that `ProducerStateManager` adds all of these empty transactions to its internal collection of `ongoingTxns` before immediately removing them. There could be tens of thousands of empty transactions in the worst case from a single `Fetch` response, so this can create a huge amount of pressure on the broker. -- This message was sent by Atlassian Jira (v8.3.4#803005)
