Patrick Hunt commented on BLUR-5:
---------------------------------
What other changes should I make before committing this? I'm thinking the
following two:
1) make the write and read caching behavior configurable - ie individually on
or off for an indexdir
2) Use the context as suggested by Doug to control default read/write cache
behavior "cache i/o that occurs in a READ or FLUSH context, but only cache
MERGE-related i/o when the estimatedMergeBytes is substantially smaller than
the cache size". I'd also make these configurable so that it would be easy to
experiment.
Other than that the full unit test suite is now passing for me so I should be
pretty close to being able to commit this. What do you think?
