Re: [rdf4j-dev] 4.0 timeline - second milestone

[jerven Bolleman <jerven.bolleman@sib.swiss>]

Hi All,

I am also very exited about the LMDB store as well as all the other 
performance work that is in this version.

Now that query-precompile is in I will do some more small improvements 
to it regarding function evaluation. So for me I am good to go.

Next big improvement is going to be multithreaded query joins. For which 
I have some ideas that will be quite effecive.

Also I want to evaluate LMDB to replace mapdb in the group by operation 
or make it store dependent.

Regards,
Jerven
