client side bloom filters

[Abhijit Pol <ap...@rocketfuel.com>]

Is there any work done or thoughts went into exposing bloom filters on
client side?

We have use case where 40-50% of lookup keys don't exists in HBase (new keys
or keys we don't care to store). We don't have strong
consistency requirements and seems like avoiding these ~40% requests going
to HBase server should help.

bloom filters are a feature of the hfile, so it might not make a lot
of direct sense to expose them.  However they should accelerate
requests when there is nothing there.
