HBase: Reading a single row from a compressed table

avatar

In Hbase as per my reading the reads happens by first checking in blockcache, if missed then Memcache,if missed then use bloom filters to check for the record and finally use index on the HFile to read the data. But what if all the data is compressed? How can it find the index and read the data from a compressed Hfile? Even if read from where does the decompression occur? Is it from client?
