Hi! I am quite sure this was asked before. But why is Flink SQL is declared to be in in Beta as given by the header in https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/table/ ?
Are there specific functions in SQL which are not production ready or is it meant for the whole Flink SQL API ? I am asking this because many large companies seem to be (Alibaba, Uber, ...) using it in production. Thanks Philip
