-------------------------------
Summary: [I18N][Performance] JcrResourceBundleProvider clears the
cache on mix:language changes
Key: SLING-2881
URL: https://issues.apache.org/jira/browse/SLING-2881
Project: Sling
Issue Type: Bug
Components: Extensions
Affects Versions: i18n 2.2.4
Environment: CQ5.6
Reporter: Rob Ryan
Performance of an appplication using Sling i18n JcrResourceBundleProvider
suffers drastically if nodes with mixin type mix:language are modified
frequently.
The reason for the performance degradation is that JcrResourceBundleProvider
registers a JCR event listener for node types: mix:language and sling:Message.
It then clears the i18n resource bundle cache whenever a node with these types
appears in an event.
The JCR 2.0 spec indicates applications should use a mix:language type as the
standard way to provide a property specifying the natural language which the
content of a node is expressed.
Therefore clearing the resource bundle cache on a change to *any* node with a
mix:language type is inappropriately broad.
