nsq v0.2.22 Release Notes

Release Date: 2013-08-26 // over 10 years ago

  • ⬆️ Upgrading from 0.2.21: message timestamps are now officially nanoseconds. The protocol docs always stated this however nsqd was actually sending seconds. This may cause some compatibility issues for client libraries/clients that were taking advantage of this field.

    🚀 This release also introduces support for TLS feature negotiation in nsqd. Clients can optionally 👀 enable TLS by using the appropriate handshake via the IDENTIFY command. See #227.

    Significant improvements were made to the HTTP publish endpoints and in flight message handling to ⬇️ reduce GC pressure and eliminate memory abuse vectors. See #242, #239, and #245.

    This release also includes a new utility nsq_to_nsq for performant, low-latency, copying of an NSQ topic over the TCP protocol.

    Finally, a whole suite of debug HTTP endpoints were added (and consolidated) under the /debug/pprof namespace. See #238, #248, and #252. As a result nsqd now supports direct profiling via Go's pprof tool, ie:

    $ go tool pprof --web http://ip.address:4151/debug/pprof/heap
