HBase read latency

2011-03-26 Thread Hari Sreekumar
Hi guys, On what factors does HBase read latency primarily depend? What would be the approx theoretical limit for read latency in v0.90.1 on a cluster of 7 nodes (16 core/16 GB RAM on 5 machines and 36 GB on the other two)? I have an application where I generate around 1000 rows/s to be input

This sounds like you are being limited by sequentially reading records in a single thread with multiple queries. Can you say more about what kind of read your doing and about the structure of the program initiating the reads? On Sat, Mar 26, 2011 at 10:01 AM, Hari Sreekumar
