Subject Fetching of the data from HFile
Date Fri, 20 Jan 2012 15:56:19 GMT
Hi,

Each HFile has multiple Data Blocks and each block has multiple K/V pairs.
So, effectively a given HFile has many K/V pairs. When a client searches
for a particular row, is the entire HFile scanned for data or some sort of
index is maintained in the HFile? Also, is the data sorted in HFile?

Thanks,
Praveen
