Subject Performance Benchmarks
Date Tue, 22 Sep 2009 17:05:13 GMT
Hi all,

I was looking at the HBase Goes Realtime presentation yesterday and came
across these numbers:

Tall Table 1 million rows with a single column
* Insert - 0.24 ms per row
* Read - 1.42ms per row
* Full Scan - 11 seconds

Wide Table 1000 Rows with 20,000 columns
* Insert - 312 ms per row
* Random Read - 121 ms/row
* Full Scan - 146 seconds

Fat Table 1000 Rows with 10 columns 1MB value
* Insert - 68 seconds
* Random Read - 56.92 ms/row
* Full Scan - 35 seconds

I'm interested in understanding whether there are any up to date stats for
performance, especially with
regards to random reads on tables with approx 10 columns and n million
rows.  I'm looking into running
a performance benchmark eventually, I just wondered whether anybody had any
stats to share?

Many thanks,
Jon.
