stack commented on HBASE-5626:
------------------------------
This would be an excellent item to work on [~nitish]. A means of being able to
view write amplification would be sweet and being able to compare compaction
algoritims would be great.
I see another issue filed recently where FB talk of adding metadata to the
files we write so more data for analyzing provenance/history.
The script attached might be a start.
Folks have used excel spreadsheet functions in the past, etc., looking at
compactions.

> A tool to run compaction simulations would be a nice to have. We could use
> it to see how well an algo ran under different circumstances loaded w/
> different value types with different rates of flushes and splits, etc.
> HBASE-2462 had one (see in patch). Or we could try doing it using something
> like this: http://en.wikipedia.org/wiki/Discrete_event_simulation
