> Currently, we already support to join a stream and a bounded stream using reguar join. However, this will be tranlsated into stream-stream join which is not efficient, because it will output early results and maybe retracted afterwards. 
> A better and native support will be using a special temporal join operator which will block the streaming side until all the static table data is loaded. 
> This can help users to join a huge table, e.g. MySQL table with billion records but changes little.
