Jay Kreps created KAFKA-741:
-------------------------------
Summary: Improve log cleaning dedupe buffer efficiency
Key: KAFKA-741
URL: https://issues.apache.org/jira/browse/KAFKA-741
Project: Kafka
Issue Type: Bug
Reporter: Jay Kreps
Two good suggestions:
1. Use a probing scheme to increase density without increasing the collision
rate
2. Only count unique updates to the offset map (i.e. if the key is all zero,
don't count it) when computing the load. Dynamically choose the end offset
based on when the map is full.
Would be good to investigate these things.
