陈梓立 commented on FLINK-9894:
----------------------------
FLINK-9875 would definitely raise data race on current data base. the code snip
associated to this issue is not thread-safe and wired.
FLINK-9875 would introduce a performance improvement and this synchronize
burden is not that heavy. I would give a benchmark, but it might be pending for
some times.
