Changes Worth Mentioning
Core Server
Enhancements
-
Binding recovery on node startup is now more efficient. This means in clusters with a lot of
queues and/or bindings, nodes start quicker.GitHub issue: #3137
-
Plugin directory paths are now deduplicated, so if a single directory is specified
more than once, the node won't complain about duplicate plugins.GitHub issue: #3155
-
Startup banner and log entries now use path separators more consistently on Windows.
Thanks to Linda @LindaLawton Lawton for pointing out the inconsistency.
GitHub issue: #3149
Shovel Plugin
Bug Fixes
-
When dynamic Shovels are started the plugin now acquires a distributed lock.
This is generally not necessary but helps avoid duplicate Shovels being started
via import of a definition file on every cluster node during cluster formation.GitHub issue: #3167
