Xuyang Zhong updated FLINK-37836:
---------------------------------
Release Note: In Flink 2.1, we introduced the new DeltaJoin operator in
stream processing jobs, along with optimizations for simple pattern jobs.
Compared to traditional dual-stream joins, DeltaJoin requires significantly
less state, effectively mitigating issues related to large state, including
resource bottlenecks, slow checkpointing, and lengthy job recovery times. This
feature is enabled by default.
