      A file system abstraction allows to add new features (cross cutting concerns) in a modular way, for example:

      • detection and special behavior of out-of-disk space situation
      • profiling and statistics over JMX
      • re-try on file system problems
      • encryption
      • file system monitoring
      • replication / real-time backup on the file system level (for clustering)
      • caching (improved performance for CRX)
      • allows to easily switch to faster file system APIs (FileChannel, memory mapped files)
      • debugging (for example, logging all file system operations)
      • allows to implement s3 / hadoop / mongodb / ... file systems - not only by us but from 3th party, possibly the end user
      • zip file system (for example to support read-only, compressed repositories)
      • testing: simulating out of disk space and out of memory (ensure the repository doesn't corrupt in this case)
      • testing: simulate very large files (using an in-memory file system)
      • splitting very large files in 2 gb blocks (FAT and other file systems that don't support large files)
      • data compression (if needed)
