Hi, 1. Flink’s Python Batch API is not complete and it’s not on pair with Scala. 2. As for know there is no Python API for Flink Streaming, however there is some ongoing work with that: https://issues.apache.org/jira/browse/FLINK-5886 <https://issues.apache.org/jira/browse/FLINK-5886> 3. CEP doesn’t work with Flink Batch, you have to use Flink Streaming for that: https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/api_concepts.html#dataset-and-datastream <https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/api_concepts.html#dataset-and-datastream>
