Sophie Blee-Goldman reopened KAFKA-7912: ---------------------------------------- The fix for this caused a performance regression and is being rolled back. We should look into alternative ways to support concurrent modifications to the underlying data structure > In-memory key-value store does not support concurrent access > ------------------------------------------------------------- > > Key: KAFKA-7912 > URL: https://issues.apache.org/jira/browse/KAFKA-7912 > Project: Kafka > Issue Type: Bug > Components: streams > Reporter: Sophie Blee-Goldman > Assignee: Sophie Blee-Goldman > Priority: Major > Fix For: 2.3.0 > > > Currently, the in-memory key-value store uses a Map to store key-value pairs > and fetches them by calling subMap and returning an iterator to this submap. > This is unsafe as the submap is just a view of the original map and there is > risk of concurrent access. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
