Constraints execute server-side.
It might work to write to an external system but it's still bogus for
proper lifecycle methods on cleanup inside Accumulo. Writing to Accumulo
within a constraint is still deadlock prone, as well.

We thought about this for text indexing. We found we could use Constraints as
they trigger on write. Seems like a bit of a hack and i have no idea if it
would blow something up.
Does constraint execution happen on tablet side or client side?

Is there a way to tie into the write process in Accumulo? Maybe just use an
Iterator that worked on compaction to send data to blur/solr? I have seen
something similar in Cassandra, a data hook to save data in Solr.

We were trying to do so, but adding visibility while adding/searching
documents needs lot more thinking. Adding visibility to core search engine
needs changes to algorithm and that does not make it very scalable.
Integration besides granular visibility is very doable. and we had taken
inspiration from Solandra.
Obviously if we can get it done it adds lot of value. I believe Sqrrl
people have already done it, are they thinking to open source it anytime in
future?

We briefly toyed with blur on accumulo but didnt get too far just because
it was obe. I think that would be cool.

It's definitely possible. I remember hearing about someone doing lucene
on top of Accumulo once, but I don't recall seeing a nice package with a
bow on top.

What lexical search package (like lucene/solr) has anyone put on top
of
accumulo? Is this possible or does everyone just index log files and
documents?
