I notice that PIP-78 has already assigned to another issue. https://mail-archives.apache.org/mod_mbox/pulsar-dev/202101.mbox/%3CCAG%3DTQOrPH49v9ToDE_aeQzEiDC%2BEgSR61ERoqanpWfQGvEB_Vw%40mail.gmail.com%3E
So, I'll change the PIP number to 79. https://github.com/apache/pulsar/wiki/PIP-79%3A-Reduce-redundant-producers-from-partitioned-producer Regards, -- Yuri Mizushima yumiz...@yahoo-corp.jp "Yuri Mizushima" <yumiz...@yahoo-corp.jp> wrote: Dear Pulsar community, When partitioned producer connects to partitioned topic, sometimes doesn't need to connect to all of partitions depending on rate, routing mode, etc. So, I drafted a PIP about reducing redundant producers from partitioned producer. I'd like to use system resources (e.g. connections between Client and Broker, memory usage of both Client and Broker) more efficiently by this feature. https://github.com/apache/pulsar/wiki/PIP-78%3A-Reduce-redundant-producers-from-partitioned-producer Feel free to ask me any questions or suggestions, etc. Best regards, -- Yuri Mizushima yumiz...@yahoo-corp.jp
