Back Spring caches with hybrid atlassian-cache Caches instead of Hazelcast (IMap-backed) caches

XMLWordPrintable

    • We collect Bitbucket feedback from various sources, and we evaluate what we've collected when planning our product roadmap. To understand how this piece of feedback will be reviewed, see our Implementation of New Features Policy.

      Spring Cache's in Stash and Bitbucket DC versions up to and including 4.7.0 are backed by Hazelcast IMap's internally. In some scenarios, this can cause cache accesses from one cluster node to block waiting for another cluster node, which in the event of OS or JVM issues (e.g., excessive GC pauses) may be slow or unresponsive.

      In Bitbucket Data Center 4.8.0 and higher, this has been replaced with hybrid-mode atlassian-cache Cache's which do not block on other cluster nodes even if they are affected by OS or JVM issues.

In some scenarios, this can cause cache accesses from one cluster node to block waiting for another cluster node, which in the event of OS or JVM issues (e.g., excessive GC pauses) may be slow or unresponsive.
