Serving images from hbase

Good afternoon. We are exploring option of serving images directly from
hbase. If we were using hbase to store images, how many disk IOPs would it
take to serve from disk the first time it is accessed?


Thanks so much,
Vadim

Depends on where the image to serve is found.  If it could be possibly
in all storefiles -- if we can't rule it out because its row key could
be present in a storefile -- and you have ten of them and no bloom
filter action going on, then it could be ten.  If we can figure the
image is in one storefile only, then its one seek.

Can you measure yourself with a test dataset?
