Now Python SDK has a SyntheticSources and it is now used in a couple of performance tests. However I find the Python SyntheticSources is much less efficient than its Java counterpart even though they are implemented in the same way (SDF). Results of https://ci-beam.apache.org/view/PerformanceTests/job/beam_PerformanceTests_TextIOIT_Python/ shows SyntheticSources costs >10 min machine time producing `25,000,000` records and https://ci-beam.apache.org/view/PerformanceTests/job/beam_PerformanceTests_xlang_KafkaIO_batch_Python/ not able to finish generating `100,000,000` records within ~30 min -- This is an automated message from the Apache Git Service.
