nsq v0.2.24 Release Notes

Release Date: 2013-12-07 // over 10 years ago

  • ⬆️ Upgrading from 0.2.23: No backwards incompatible changes. However, as you'll see below, quite a few command line flags to the utility apps (nsq_to_http, nsq_to_file, nsq_to_http) were 🚀 deprecated and will be removed in the next release. Please use this release to transition over to the new ones.

    NOTE: we are now publishing additional binaries built against go1.2

    The most prominent addition is the tracking of end-to-end message processing percentiles. This measures the amount of time it's taking from PUB to FIN per topic/channel. The percentiles are configurable and, because there is some overhead in collecting this data, it can be turned off 👀 entirely. Please see the section in the docs for implementation details.

    ➕ Additionally, the utility apps received comprehensive support for all configurable reader options 💻 (including compression, which was previously missing). This necessitated a bit of command line flag cleanup, as follows:

    nsq_to_file

    • deprecated --gzip-compression in favor of --gzip-level
    • deprecated --verbose in favor of --reader-opt=verbose

    nsq_to_http

    • deprecated --throttle-fraction in favor of --sample
    • deprecated --http-timeout-ms in favor of --http-timeout (which is a duration flag)
    • deprecated --verbose in favor of --reader-opt=verbose
    • deprecated --max-backoff-duration in favor of --reader-opt=max_backoff_duration=X

    nsq_to_nsq

    • deprecated --verbose in favor of --reader-opt=verbose
    • deprecated --max-backoff-duration in favor of --reader-opt=max_backoff_duration=X

    🆕 New Features / Enhancements:

    • #280 - add end-to-end message processing latency metrics
    • #267 - comprehensive reader command line flags for utilities
