> The note in [https://ci.apache.org/projects/flink/flink-docs-release-1.5/dev/datastream_api.html#collection-data-sources]
> states that Collecitons are mainly there for testing and do not support parallelism. I believe this to be an unnecessary assumption - I'm sure there are plenty of use cases that already have the data they need to distribute ready at hand. It seems strange that a fixed collection of inputs cannot be parallelised by Flink, which would require users to write their Collections into a text file and re-read them just to get parallelisation.
