For implementing CopyOnReadDirectory (OAK-1724) I need to copy the Lucene index content to a local directory. However as there can be multiple Lucene indexes and they may be at non root location (OAK-2211) I need a way to map the JCR path of index to path on local filesystem.
For e.g. if we have indexes defined at /oak:index/lucene /oak:index/prop1 /foo/oak:index/prop1 /foo/bar/oak:index/prop2 And on File system say they need to be stored under /repository/lucene. Then I need a way to map them. Approach A - Map JCR path to FileSystem path --------------------------------------------------------------- One simple way would be to recreate the JCR path structure under /repository/lucene. So path on filesystem would be /repository/lucene/oak_index/lucene /repository/lucene/oak_index/prop1 ... Here we would need to do some encoding such that JCR names can be safely used on filesystem Approach B - Define a unique name ------------------------------------------------ Here we let user define a unique name for the index and use that. Or going even further we let user define the path for the index So which approach to use For ease of out of the box use I would prefer auto mapping but then need to be sure if mapping the JCR path to filesystem (only for index data) would be safe to use?
