I support this proposal. Coping here my comments from GH: can't we enable this by default in case we detect that the connected Broker supports it ? I can't find any reason for not using this mechanism if it is available.
Maybe we can set the default to "true" and allow users to disable it in case it impacts their systems in an unwanted way. Maybe It would be useful to have a way to disable the mechanism on the broker side as well Enrico Il giorno mer 22 feb 2023 alle ore 10:22 houxiaoyu <anonhx...@gmail.com> ha scritto: > > Hi Pulsar community: > > I opened a PIP to discuss "Notifications for partitions update" > > ### Motivation > > Pulsar client will poll brokers at fix time for checking the partitions > update if we publish/subscribe the partitioned topics with > `autoUpdatePartitions` as true.
