Liya Fan created FLINK-12687: -------------------------------- Summary: ByteHashSet is always in dense mode Key: FLINK-12687 URL: https://issues.apache.org/jira/browse/FLINK-12687 Project: Flink Issue Type: Improvement Components: Runtime / Operators Reporter: Liya Fan Assignee: Liya Fan
Since there are only 256 possible byte values, the largest possible range is 255, and the condition range < OptimizableHashSet.DENSE_THRESHOLD must be satisfied. So ByteHashSet must be in dense mode. We can make use of this to improve the performance and code structure. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
