xuqianjin edited comment on FLINK-10999 at 11/29/18 10:25 AM: -------------------------------------------------------------- hi [~fhueske] Thank you very much. I can indeed support rowtime and proctime in a table, but I convert and execute according to his code successively. Proctime is added to the first table, and rowtime is added to the second table after converting to stream, I find that the execution plan is one layer short of rowtime operation conversion. was (Author: x1q1j1): hi [~fhueske] Thank you very much.
