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. > [1] https://beam.apache.org/documentation/io/testing/ -- This message was sent by Atlassian JIRA (v6.4.14#64029)
