[GitHub] [pulsar-client-go] dferstay edited a comment on pull request #319: Do not allocate MessageIDs on the heap

   Below is the alloc_space view of a pprof heap profile collected during a large scale test of a high-throughput service that uses pulsar-client-go to send messages to Pulsar.  Note that `messageID` structures account for 6.07% of all allocation; this percentage grows the longer the service runs as messageIDs escape to the heap for every message produced.
