Subject doing upsert possible?
Date Thu, 24 Jul 2014 23:06:15 GMT
if we have a huge table, and every 1 hour only 1% of that has some updates,
it would be a huge waste to slurp in the whole table through MR job and
write out the new table.

instead, if we store this table in HBASE, and use the current HBase+Hive
integration, as long as we can do upsert, then we can afford to touch only
that 1% of entries, and the result can be very fast.
