Review comment:
Do you suggest creating a separate JIRA for that?

> Add performance tests for commonly used file-based I/O PTransforms
> ------------------------------------------------------------------
>
> Key: BEAM-3060
> URL: https://issues.apache.org/jira/browse/BEAM-3060
> Project: Beam
> Issue Type: Test
> Components: sdk-java-core
> Reporter: Chamikara Jayalath
> Assignee: Szymon Nieradka
>
> We recently added a performance testing framework [1] that can be used to do
> following.
> (1) Execute Beam tests using PerfkitBenchmarker
> (2) Manage Kubernetes-based deployments of data stores.
> (3) Easily publish benchmark results.
> I think it will be useful to add performance tests for commonly used
> file-based I/O PTransforms using this framework. I suggest looking into
> following formats initially.
> (1) AvroIO
> (2) TextIO
> (3) Compressed text using TextIO
> (4) TFRecordIO
> It should be possibly to run these tests for various Beam runners (Direct,
> Dataflow, Flink, Spark, etc.) and file-systems (GCS, local, HDFS, etc.)
> easily.
> In the initial version, tests can be made manually triggerable for PRs
> through Jenkins. Later, we could make some of these tests run periodically
> and publish benchmark results (to BigQuery) through PerfkitBenchmarker.
