Hi all, Currently the Java implementation to get the partition index of a topic name is not correct. See https://github.com/apache/pulsar/pull/8341/files#diff-445b0cfa56ca0c784df78e73d9294f2a37f079ca3c15c345b03c09d56f81ebff <https://github.com/apache/pulsar/pull/8341/files#diff-445b0cfa56ca0c784df78e73d9294f2a37f079ca3c15c345b03c09d56f81ebff> for the unit tests I added.
I also noticed the problem in https://github.com/apache/pulsar/pull/10850 <https://github.com/apache/pulsar/pull/10850> because transaction buffer snapshot topic name may be `xxx-partition-0-yyy`, which should not be treated as a partitioned topic. Since Pulsar is 2.9.0-SNAPSHOT now, is it proper to correct the implementation? What I concerned is the compatibility because we can’t assume users never used a topic name like `my-topic-partition-000` to reference the partition 0 of `my-topic`. If the behavior was corrected, `my-topic-partition-000` would be treated as a non-partitioned topic. I'm not sure if this change could have a wide influence, so I want to begin a discussion about it. Thanks, Yunze
