Yun Tang commented on FLINK-24918: ---------------------------------- [~aitozi], I think the suggestion make sense as different disk would have performance impact for RocksDB like state-backend. Current root dir actually relays on Java's File#createTempFile, which could be changed with system property {{java.io.tmpdir}}. I think we could introduce new option to configure the root dir and give explicit descriptions in https://github.com/apache/flink-benchmarks documentation. Do you want to take this ticket? > Support to specify the data dir for state benchmark > ---------------------------------------------------- > > Key: FLINK-24918 > URL: https://issues.apache.org/jira/browse/FLINK-24918 > Project: Flink > Issue Type: Improvement > Components: Benchmarks, Runtime / State Backends > Reporter: Aitozi > Priority: Minor > > {{StateBackendBenchmarkUtils}} use null as the parent dir to create temp dir, > which will finally use the /tmp as the data dir. It has two downsides: > 1. the /tmp dir often mount with tmpfs, which may store data in memory. it > will affect the result of rocksdb benchmark > 2. It can not support to use benchmark to measure the performance on a new > device. > So I purpose to enhance the state benchmark to support specify the default > data dir. And avoiding to use the {{/tmp}} as default. -- This message was sent by Atlassian Jira (v8.20.1#820001)
