nsq v0.2.25 Release Notes

Release Date: 2014-02-05 // about 10 years ago

  • ⬆️ Upgrading from 0.2.24: No backwards incompatible changes.

    🚀 This release adds several commonly requested features.

    🔧 First, thanks to @elubow you can now configure your clients to sample 👀 the stream they're subscribed to. To read more about the details of the implementation see #286 and the original discussion in #223. Eric also contributed an improvement to nsq_tail to add the ability to tail the last N messages and exit.

    👍 We added config file support (TOML) for 🚀 nsqd, nsqlookupd, and nsqadmin - providing even more deployment flexibility. Example configs 💻 are in the contrib directory. Command line arguments override the equivalent option in the config file.

    We added the ability to pause a topic (it is already possible to pause individual channels). This functionality stops all message flow from topic to channel for all channels of a topic, queueing at the topic level. This enables all kinds of interesting possibilities like atomic channel renames and trivial infrastructure wide operations.

    🍱 Finally, we now compile the static assets used by nsqadmin into the binary, simplifying 🚀 deployment. This means that --template-dir is now deprecated and will be removed in a future 🚀 release and you can remove the templates you previously deployed and maintained.

    • #286 - add client IDENTIFY option to sample a % of messages
