Class NonDefaultMountWriteReportingObserver

java.lang.Object
org.apache.jackrabbit.oak.composite.impl.NonDefaultMountWriteReportingObserver
All Implemented Interfaces:
Observer

public class NonDefaultMountWriteReportingObserver extends Object implements Observer
Reports writes to non-default mounts

This is a diagnostic observer and is expected to be used in scenarios where the CompositeNodeStore is configured in a 'seed' mode, where the non-default mounts are write-enabled.

In such scenarios it is useful to report writes to non-default mounts from components that are unexpected. For instance, it can report all writes that do not originate from the FileVault package installer.

Performance note: the overhead of this observer has not been measured, but as it is designed to be used only for initial setups the performance impact should not matter.
