Zipkin 3.1.1 is a hardening release, notably polishing out some UI glitches and experience problems for Cassandra users. Thanks a lot for all the feedback and patience, as we delayed this patch until we felt confident glitches were handled in a way that would be easy to diagnose in the future!

UI Fixes

Users and maintainers have noticed a few glitches since our UI moved from the abandoned react-scripts to vite for packaging. We think we've corrected everything at this point, but please reach out if you believe we didn't.

  • Fixed our test image ghcr.io/openzipkin/zipkin-ui resulting in 404s
  • Fixed handling of the env variable ZIPKIN_UI_BASEDIR, used when zipkin is deployed in a proxying
    • added a new ghcr.io/openzipkin/zipkin-uiproxy image that proves this works.
    • A lot of folks pitched in here, special thanks to @ujo-trackunit who uses this and provided a lot of insight leading to the fix, as well @SamTV12345 @reta and @anuraaga who all took time away to contribute towards resolution.

Cassandra and SASI default change

When STORAGE_TYPE=cassandra3, zipkin uses a feature called SASI for search features. This was enabled by default in Cassandra 3.11+, but in 4.x it became disabled by default.

Unlike schema settings, sasi_indexes_enabled: true is not something zipkin can change. Before, we weren't logging this critical setup problem, so users upgrading from cassandra 3 to 4 had a very hard time figuring it out. We now properly log what's going on, with more context. Ideally, this will help folks correct their configuration.

Here's an example, if you use the default cassandra docker image which has SASI disabled

2024-03-07T08:02:47.184+08:00 ERROR [/] 83635 --- [cking-tasks-2-1] z.s.c.Schema                             : Failed to execute [CREATE CUSTOM INDEX IF NOT EXISTS ON zipkin2.span (l_service) USING 'org.apache.cassandra.index.sasi.SASIIndex'
   WITH OPTIONS = {'mode': 'PREFIX'}]: SASI indexes are disabled. Enable in cassandra.yaml to use.

Build updates

While these changes won't impact end users, they do affect forks and are important.

  • we moved from long form license headers to SPDX ID
  • @anuraaga fixed our ServerIntegratedBenchmark
