Performance with many KV's per row

[Al Lias <al...@gmx.de>]

If I have many values for a given row/family, will they be scanned
sequentially upon retrieval (say with a get) in the region server?

Is it a difference, if I look for a specific column or a timestamp (or
range) or any other Filter?

The Bloomfilter (once back) will help here?

thx,

  Al

Hey Al!
There are indexes to the files that you are looking in but as far as I know
not to all rows
which means that you have to "scan" a few keyvalues before getting to the
one you want.

The BloomFilter would only help in the case of a Get operation, for a Scan
you still need
to open up all files. The only thing that filters and specifying a timestmp
for example does
is to return faster, the approach is still the same.

Hope that helps
