+ === August 19, 2006 ===
+ I have done a bit in the last month. I have two different implementations of CacheManager:
(1) the PluggableCache and (2) ClockProCache. The ClockProCache is my implementation of the
ClockPro algorithm within the Derby CacheManager interface. The PluggableCache is my attempt
to separate the cache implementation from the replacement policy. The nice thing is that many
policies can easily be tried with this approach.
+ To conclude my summer work, I have written a report detailing my efforts [http://www.eecg.toronto.edu/~gokul/derby/derby-report-aug-19-2006.pdf
PDF]. In addition, I have placed by code here [http://www.eecg.toronto.edu/~gokul/derby/code/aug-19-2006/
CODE]. There is much more work to do. I will continue working on this addition to Apache Derby.

  With some simple code changes, I modified the mirrored cache implementation to have almost
no overhead (only 1% now).
