[jira] [Commented] (FLINK-33539) Potential regression (Nov. 7th): listAddAll on RocksDB with Java8
[ https://issues.apache.org/jira/browse/FLINK-33539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17785734#comment-17785734 ]
Zakelly Lan commented on FLINK-33539:
-------------------------------------
Seems introduced by FLINK-5865 (cee2611e). Manually triggered benchmark:
Before this commit:
{code:java}
11:11:13 Benchmark (backendType) Mode Cnt Score Error Units
11:11:13 ListStateBenchmark.listAddAll HEAP thrpt 30 820.639 ± 6.355 ops/ms
11:11:13 ListStateBenchmark.listAddAll ROCKSDB thrpt 30 290.898 ± 4.836 ops/ms
11:11:13 ListStateBenchmark.listAddAll ROCKSDB_CHANGELOG thrpt 30 170.711 ± 9.054 ops/ms {code}
After this commit:
{code:java}
11:31:29 Benchmark (backendType) Mode Cnt Score Error Units
11:31:29 ListStateBenchmark.listAddAll HEAP thrpt 30 817.607 ± 6.156 ops/ms
11:31:29 ListStateBenchmark.listAddAll ROCKSDB thrpt 30 276.837 ± 3.548 ops/ms
11:31:29 ListStateBenchmark.listAddAll ROCKSDB_CHANGELOG thrpt 30 170.888 ± 10.792 ops/ms {code}
What's strange is, there's no regression on other state backends, as well as with higher java version. Only RocksDB with Java8 is affected.
