------------------------------
Summary: Improved caching for DataStore
Key: OAK-4837
URL: https://issues.apache.org/jira/browse/OAK-4837
Project: Jackrabbit Oak
Issue Type: Improvement
Components: blob
Reporter: Amit Jain
Assignee: Amit Jain
The current CachingDataStore implementation used with S3DataStore has certain
problems:
* Lack of stats to show hit rate/miss rates for files being requested for
downloads
* Lack of stats for async uploads
* Async upload functionality leaks into Backend implementations, LocalCache
classes.
* The call to {{DataStore#getRecord()}} which makes multiple calls to backends
which is problematic for S3 (i.e. when not being served bu cache)
* There is some functionality which is not used with Oak like length cache,
sync/async touch etc. which can be removed and code simplified.
