Hi
I am Saikat, I am new to Apache Jena and I would like to contribute to
SPARQL Query Caching (https://issues.apache.org/jira/browse/JENA-626).
I would like to know if someone has already taken up the issue and
currently working on it. I have reviewed the old messages in developers
mail list and I suppose this issue is currently still Unassigned.

Hi Saikat,
Good to check - no one seems have mentioned it any time recently.
There is some code:
https://svn.apache.org/repos/asf/jena/Experimental/sparql-cache/README.markdown
which is an external cache and has some issues:
1/ Updates don't invalidate the cache
2/ It's a rough prototype in scala I knocked together, not production tested
3/ Claims of "rate control" are overstated (there isn't any).
(seems strange to have it in the cache code at all)
In Fuseki2, there is a server work area on disk so putting results
somewhere on disk now makes more sense. Or memcached.
