Fabian Hueske commented on FLINK-4679   Re: Add TumbleRow row-windows to Table API Hi Haohui Mai, Table API and SQL share the optimization and execution code. Both APIs are translated into the same logical representation (Calcite's RelNodes). From there on, there is should be as little distinction between both APIs as possible. The translation of the Table API and SQL is shown in this slide set. Table API TumbleRow windows can be expressed es regular SQL OVER windows with a partitioning based on time (this was initially excluded from the SQL OVER windows). The question is whether we can reuse the existing code for SQL OVER (I think it can) without major performance penalties (not clear yet) or whether we need a special execution strategy for partitioning on time to make this more efficient.
