nsq v0.2.31 Release Notes

Release Date: 2014-08-26 // over 9 years ago

  • ⬆️ Upgrading from 0.2.30: No backwards incompatible changes.

    🚀 This release includes a few key changes. First, we improved feedback and back-pressure when nsqd writes to disk. Previously this was asynchronous and would result in clients not knowing that their 🐎 PUB had failed. Interestingly, this refactoring improved performance of PUB by 41%, by removing the topic's goroutine responsible for message routing in favor of N:N Go channel communication. 👀 For details see #437.

    🐳 @paddyforan contributed official Dockerfiles that are now built automatically via Docker Hub. Please begin to use (and improve these) as the various older images we had been maintaining will be 🗄 deprecated.

    The utility apps deprecated the --reader-opt flag in favor of --consumer-opt and nsq_to_nsq 🔧 and to_nsq received a --producer-opt flag, for configuring details of the connection publishing 🔧 to nsqd. Additionally, it is now possible to configure client side TLS certificates via tls_cert and tls_key opts.

    👀 As usual, we fixed a few minor bugs, see below for details.
