ccf0fcd5 - A number of smaller fixes and performance improvements:

Wed, 22 Jun 2011 02:36:45 +0000

A number of smaller fixes and performance improvements:- Implemented Get() directly instead of building on top of a full merging iterator stack. This speeds up the "readrandom" benchmark by up to 15-30%.- Fixed an opensource compilation problem. Added --db= flag to control where the database is placed.- Automatically compact a file when we have done enough overlapping seeks to that file.- Fixed a performance bug where we would read from at least one file in a level even if none of the files overlapped the key being read.- Makefile fix for Mac OSX installations that have XCode 4 without XCode 3.- Unified the two occurrences of binary search in a file-list into one routine.- Found and fixed a bug where we would unnecessarily search the last file when looking for a key larger than all data in the level.- A fix to avoid the need for trivial move compactions and therefore gets rid of two out of five syncs in "fillseq".- Removed the MANIFEST file write when switching to a new memtable/log-file for a 10-20% improvement on fill speed on ext4.- Adding a SNAPPY setting in the Makefile for folks who have Snappy installed. Snappy compresses values and speeds up writes.git-svn-id: https://leveldb.googlecode.com/svn/trunk@32 62dab493-f737-651d-591e-8d6aee1b9529 List of files: /leveldb-1.20/TODO
