This sub-partitioning, which produces a > set of key groups, allows to easily scale in and out Flink jobs by simply > reassigning the different key groups to the new set of sub tasks. The idea of > key groups is described in this design document [1]. > [1] > https://docs.google.com/document/d/1G1OS1z3xEBOrYD4wSu-LuBCyPUWyFd9l3T9WyssQ63w/edit?usp=sharing -- This message was sent by Atlassian JIRA (v6.3.4#6332)
