sherpa Initial checkin of sherpa backend. These files probably don't belong here in the long term, but this is expedient. 2010-02-26 18:52:25 +00:00
test admission control *almost* works; c1 sometimes blocks for a long time when a new c2 is created 2010-05-26 00:58:17 +00:00
util adding a few overlooked files 2010-03-03 23:21:08 +00:00
adriana-lima.awk initial import; removed cruft from mert's tarball, tweaked make's clean targets 2010-01-23 02:13:59 +00:00
CMakeLists.txt Rewrite merge thread synchronization code, update status messages, implement preliminary (and ineffective) admission control, and force write merged data every megabyte (so that prograess can be tracked by admission control. Also, refactor quite a few things. 2010-05-19 23:42:06 +00:00

datatuple.h Generalized comparator, fixed some bugs in record length handling. 2010-02-23 17:05:47 +00:00
diskTreeComponent.cpp admission control is now behaving properly (but there are still no concurrent writes, or bounds on how long admission control throttles a given writer) 2010-05-21 23:43:17 +00:00

logserver.cpp restore support for concurrent disk reads; logserver was accidentally using a findTuple function that assumed diffs. This commit uses rwlc, and requires Stasis -r1393 or better 2010-05-27 01:49:27 +00:00
logserver.h Refactoring of logtable. Cleaned a bunch of includes, and logtable is now a template. This is in preparation for the new merge policy 2010-03-17 21:51:26 +00:00
logstore.cpp improved concurrency for merger. not happy with worst case write latency on my dev machine anymore (seems to be less than 2.5 seconds, up from less than 1). 2010-06-17 04:49:19 +00:00
logstore.h more bugfixes / cleanup. latching is probably overly conservative at this point, but ycsb bulkload finally seems to work 2010-05-28 01:29:10 +00:00
memTreeComponent.cpp Refactoring of logtable. Cleaned a bunch of includes, and logtable is now a template. This is in preparation for the new merge policy 2010-03-17 21:51:26 +00:00

network.h Reopening existing trees now seems to work (no thorough tests yet). Added some network opcodes for statistics and debugging (not all are implemented yet). Reduce verbosity of server and client library. 2010-03-01 21:26:07 +00:00
