Subject Lucene's FST for the block index
Date Thu, 02 Jun 2011 16:09:39 GMT
Lucene has a compact FST (Finite State Transducer) that's used for the
sorted terms index.  I think this is the same type of functionality as
the HBase block index, eg, a sorted index of row ids?  The FST is more
compact keeping every Nth row id in RAM.  Does the HFile format allow
pluggable block index implementations?

I posted this to Jira issues however that's probably not the best place.
