Thomas Mueller commented on OAK-56: ----------------------------------- > I'm fine with leaving the code in svn for now if there's a reasonable > expectation that we'll be using it down the line for a native Oak disk > persistence instead of always using an externally developed database for > storage. We already have a "native Oak disk persistence": the file data store. > File system abstraction > ----------------------- > > Key: OAK-56 > URL: https://issues.apache.org/jira/browse/OAK-56 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: core, mk > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Priority: Minor > > 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) -- This message is automatically generated by JIRA.
