Chetan Mehrotra commented on OAK-3090:
--------------------------------------
[~tmueller] Would it be possible to add support
[RemovalListener|http://docs.guava-libraries.googlecode.com/git-history/release/javadoc/com/google/common/cache/RemovalListener.html]
to {{CacheLIRS}}. Then we can use that to implement above caching
> Caching BlobStore implementation

> Key: OAK-3090
> URL: https://issues.apache.org/jira/browse/OAK-3090
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: blob
> Reporter: Chetan Mehrotra
> Fix For: 1.3.4
>
>
> Storing binaries in Mongo puts lots of pressure on the MongoDB for reads. To
> reduce the read load it would be useful to have a filesystem based cache of
> frequently used binaries.
> This would be similar to CachingFDS (OAK-3005) but would be implemented on
> top of BlobStore API.
> Requirements
> * Specify the max binary size which can be cached on file system
> * Limit the size of all binary content present in the cache
