Fix Version/s:

Description

« Hide

There some use cases when document properties set changes durning the application execution time. It would be usefull to have an ability to add resource property mapping of such dynamic resource/document at runtime.

Exposing InternalCompass.getMappings() (or simmillar) and handle it's content changes at runtime for RSEM mapping would be a nice.

I have added the ability to rebuild Compass after removing and adding ResourceMappings. You can keep ResourceMapping around and then add/remove property mappings. Once done, you can remove the alias mappings from the Compass instance, add the updated one, and rebuild it. See ~~CMP-620~~. Does that sound ok?

Sounds good. How this rebuild process affects pending transactions?
By the way will this rebuild process reinitialize subindexes defined by custom SubIndexHash?

The rebuild process closes the "old" Compass instance after (by default) a minute and tries to perform a graceful shutdown. If you expect to have a transaction longer than 60 second, you can configure it.

Regarding sub index hashing, think of the rebuild process as if you closed and opened a new Compass instance with the updated mappings.
