Thomas Mueller commented on OAK-3005:
-------------------------------------
I think there is a flaw in my previous comment: I have assumed that "no change"
would now result in "caching enabled". That would not be a good idea if the
data store is on a local file system, because it would unnecessarily add a
cache. So instead:
h2. How to configure CachingFDS
* PID org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore (same as
before, but now it means caching file data store)
h3. Fresh Installation:
* {{path}}: path of NAS or SAN storage (required)
* {{cacheSize}}: default is 0, set to a reasonable value
* {{cachePath}}: (optional) path of local file system cache. Default is
$\{home.dir\}/repository/datastoreCache.
h3. Migration from FileDataStore on SAN to CachingFDS on SAN
* {{cacheSize}}: set to a reasonable value
h3. Migration from FileDataStore on local file system to CachingFDS on SAN
* copy all files from local file system to SAN
* {{path}}: change to SAN path
* {{cacheSize}}: set to a reasonable value
h3. Keep FileDataStore on local file system
* no change (cacheSize is 0 by default, so caching is disabled)
