gabor@google.com 7263023651 Bugfixes: for Get(), don't hold mutex while writing log. - Fix bug in Get: when it triggers a compaction, it could sometimes mark the compaction with the wrong level (if there was a gap in the set of levels examined for the Get). - Do not hold mutex while writing to the log file or to the MANIFEST file. Added a new benchmark that runs a writer thread concurrently with reader threads. Percentiles ------------------------------ micros/op: avg median 99 99.9 99.99 99.999 max ------------------------------------------------------ before: 42 38 110 225 32000 42000 48000 after: 24 20 55 65 130 1100 7000 - Fixed race in optimized Get. It should have been using the pinned memtables, not the current memtables. git-svn-id: https://leveldb.googlecode.com/svn/trunk@50 62dab493-f737-651d-591e-8d6aee1b9529		13 年前
