> 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
> Assignee: 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.
