> For the purpose of reduce the sync-api send message latency, client will flush messages to broker when you call the sync-api. @dao-jun Yes, this is reasonable, but the problem is that this doesn't seem to be documented any where. I found the flushing logic here: https://github.com/apache/pulsar/blob/ffff639a1b73a34bbb5115503d4c7783bb2a2770/pulsar-client/src/main/java/org/apache/pulsar/client/impl/TypedMessageBuilderImpl.java#L82-L86 I think @ragaur-tibco's issue report is great and the minimum resolution is to document the behavior. It seems that there could be a use case where one would want to achieve batching while using the synchronous API. That's not currently supported. We have 2 options for resolving this: 1. Documenting the behavior and making it explicit that synchronous send will trigger flushing of the current batch message. 2. Adding support for controlling the triggering behavior so that batching would be possible also with the synchronous API. -- This is an automated message from the Apache Git Service.
