|
logserver.cpp
|
add new server implementation that uses FILE to buffer I/O, and handles a smaller, fixed number of connections -- leads to an almost 4x speedup on no-ops on nehalem
|
2010-08-11 22:46:55 +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

re-re-re-...re-disable new buffer manager optimizations

logstore.h
|
reduce default datapage_size to 1 (4096) to avoid useless seeks for small values

memTreeComponent.h
|
remove old comments
|
2010-08-24 00:40:48 +00:00 |
|
mergeManager.cpp
|
loosen some scheduling parameters
|
2010-12-08 19:46:55 +00:00 |
|
mergeManager.h
|
added bulk-insert APIs, prevent c1-c2 from outrunning c0-c1 by too much, and fix the overshoot computations in merge manager (roughly corresponds to run 20)
|
2010-08-30 22:22:25 +00:00 |
|
merger.cpp
|
conservatively make the bloom filter really big (should behave well down to 100 byte keys, waste ram otherwise...)
|
2010-10-05 16:55:29 +00:00 |
|
merger.h
|
two unrelated changes: release rb_mut before getting header_mut on read path (breaks delta tuples), and implement first-cut support for pulling in statistics when reopening logstores (required for correct recovery)
|
2010-06-21 20:03:05 +00:00 |
|
mergeStats.cpp
|
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 |
|
mergeStats.h
|
scattered, and poorly tested fixes. finer grained latching for tree nodes; throttle c0-c1 merge when c0 is small; fix delta computations for c0 throttling; disable short pauses for c1-c2 merge. this gets the bulk load throughput up to 8500, but workloada is still slow

network.h
|
port to newer gcc/g++
|
2010-10-02 12:52:41 +00:00 |
|

add memTreeComponent::batchedRevalidatingIterator; amortize cost of red black latching during merge
