That is to be able to push an object that implements GenericRecord. Here you are using the builder provided by Pulsar but this is mo enough for me, because my user would like to use an object from his own domain, just by implementing Pulsar GenericRecord java interface, because we will save resources (allocations and cycles) https://github.com/apache/pulsar/pull/9481/files#diff-bbdf586ddad181a0a9dae17974b19ca5cbbce398716ec7fa5b4c45b69be58f41R66 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
