------------------------------
Summary: 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
Reporter: Aitozi
{{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.
