I have another query, this time relating to ARQ and how I can extend it.
*Background*

I am using HBase as the underlying Data Store for Triples (by implementing
various Jena Extension points).
So far so good.
But now I have certain SPARQL queries that have FILTER operations defined.
With a huge data set, that I have, its taking a lot of time to FILTER the
data out.

So, I want to extract the FILTER portion of the Query out and simply want
to pass it as a HBase Filter to the HBase client so that filtering can
happen at RegionServer level itself.

This question is very similar to the question here
<https://stackoverflow.com/questions/48648677/apache-jena-arq-filter-optimization?rq=1>
on
stackoverflow.

I have been reading about ARQ and OpExecutor and believe that it may be
what I need but I cant seem to find a simple example on which I can build
up.

Can someone help me with getting to understand how I can parse the incoming
query to REMOVE the FILTER clause from it and instead take the filter
statement and evaluate it.

Thanks,
