Liu created FLINK-11050: --------------------------- Summary: When IntervalJoin, get left or right buffer's entries more quickly by assigning lowerBound Key: FLINK-11050 URL: https://issues.apache.org/jira/browse/FLINK-11050 Project: Flink Issue Type: Improvement Components: State Backends, Checkpointing Affects Versions: 1.7.0, 1.6.2 Reporter: Liu Fix For: 1.7.1
When IntervalJoin, it is very slow to get left or right buffer's entries. Because we have to scan all buffer's values, including the deleted values which are out of time range. These deleted values's processing consumes too much time in RocksDB's level 0. Since lowerBound is known, it can be optimized by seek from the timestamp of lowerBound. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
