Summary: Test failure:
org.apache.cassandra.io.sstable.indexsummary.IndexSummaryTest#testLargeIndexSummary
Key: CASSANDRA-21170
URL: https://issues.apache.org/jira/browse/CASSANDRA-21170
Project: Apache Cassandra
Issue Type: Bug
Components: Local/Compaction
Reporter: Sam Lightfoot
Assignee: Sam Lightfoot
Fix For: 5.1
[https://pre-ci.cassandra.apache.org/job/cassandra/347/testReport/junit/org.apache.cassandra.db.compaction.simple/CompactionDeleteRowRangeTest/Tests___test_jdk11_2_20___test2DeleteRangeWithOverlapingBoundAndSameTimestampCompaction__jdk11_x86_64/]
[https://pre-ci.cassandra.apache.org/job/cassandra/351/testReport/junit/org.apache.cassandra.db.compaction.simple/CompactionDeleteRowRangeTest/Tests___test_jdk11_2_20___test2DeleteRangeWithOverlapingBoundAndSameTimestampCompaction__jdk11_x86_64/]
The two deletes use the same CQL timestamp, so compaction should merge their
overlapping range tombstones into a single open/close pair (no boundary
markers). However, DeletionTime also includes local_delete_time (wall-clock
seconds), which may differ between deletes if a second boundary is crossed
during the flush. Differing local_delete_time causes the merger to treat them
as distinct deletions, producing boundary markers instead. Using
executeInternalWithNowInSec with a fixed nowInSec ensures both deletes get
identical DeletionTime values.
