> Fix For: 0.20

>
> Currently {{FileDataStore.getAllIdentifiers}} evaluates all file eagerly and
> maintains the set in memory
> As an optimization i.e. prevent loading of all file names in memory we can
> use com.google.common.io.Files#fileTreeTraverser. This is currently used in
> org.apache.jackrabbit.oak.spi.blob.FileBlobStore#getAllChunkIds
> Same logic can be done for OakFileDataStore which extends the FileDataStore
