Hi all I want to start a vote on PIP -373: add a topic's system prop that indicates whether users have published TXN messages in before.
Proposal link: https://github.com/apache/pulsar/pull/23210 Discussion link: https://lists.apache.org/thread/7mblhyvsrw5zybo0gs5512xg8f9sm67v The vote will stay open for at least 48 hours. Thanks Yubiao Feng
