Production-readyness of Flink SQL

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

Hi Philip,

you are absolutely right that Flink SQL is definitely production ready. 
It has been developed for 2 years now and is used at Uber, Alibaba, 
Huawei and many other companies.

We usually only merge production ready code or add an explicit warning 
about it. I will finally remove this tag.

Regards,
Timo
