-----------------------------------
Summary: Replace for/foreach/map in aggregates by while loops
Key: FLINK-5983
URL: https://issues.apache.org/jira/browse/FLINK-5983
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Timo Walther
Right now there is a mixture of different kinds of loops within aggregate
functions. Although performance is not the main goal at the moment, we should
focus on performant execution especially in this runtime functions.
e.g. {{DataSetTumbleCountWindowAggReduceGroupFunction}}
We should replace loops, maps etc. by primitive while loops.
