---------------------------------
Summary: i18n ResourceBundleProvider is called for every change in
the repo
Key: SLING-10884
URL: https://issues.apache.org/jira/browse/SLING-10884
Project: Sling
Issue Type: Improvement
Components: i18n
Affects Versions: i18n 2.5.16
Reporter: Joerg Hoh
The i18n ResourceBundleProvider is registered as ResourceChangeListener and
configured to listen to all changes within the repository.
And if the change does not affect a languageRoot (that's probably the vast
majority of changes), it will always open (and close) a ResourceResolver. This
comes with some overhead (500-1000 µs, depending on setup).
It should be possible to exclude some paths from being considered at all by
configuration (maybe already at the level of the registration of the properties
of the ResourceChangeListener, otherwise as part of the {{onChange}} method),
so that the creation of this ResourceResolver can be avoided. In this case no
ResourceBundles will be detected below these configured paths.
The default should remain as is.
(Although I think it could be beneficial to add /var/eventing and /var/jobs by
default to these paths, as there shouldn't be ResourceBundles there, and also
in these paths there are a lot of changes if Sling Jobs are used.)
