------------------------------------
Summary: Stream-stream join v4: skip accessing secondary index for
non-timestamp workload
Key: SPARK-56406
URL: https://issues.apache.org/jira/browse/SPARK-56406
Project: Spark
Issue Type: Improvement
Components: Structured Streaming
Affects Versions: 4.2.0
Reporter: Jungtaek Lim
For non-timestamp workload in stream-stream join v4, we don't really get
benefit from having secondary index. The purpose of secondary index is eviction
and non-timestamp workload does not perform eviction at all, hence we don't
really need to read and update secondary index.
