The changes are as follows: + +[#350] Checkpoint the metadata after successful schema-level operations. + Otherwise, if process exits without closing the connection or + running a checkpoint, created objects exist but there is no record + in the metadata. + +[#351] Don't put checkpoint extent blocks on the available list, blocks on + it are considered for truncation; they have to go on the "checkpoint + available" list. + +* Choose LSM merges based on a measure of efficiency (levels collapsed per + record), rather than simply choosing a minor or a major merge. Tweak the + merge heuristic so we don't end up with runs of smaller chunks in the + middle of the tree. + +* Add a connection-wide flag to disable LSM merges. + +* Don't create Bloom filters for the oldest chunk in the system. Add the + ability to disable Bloom filters entirely. + +* Fix fast-path for bit values in WT_CURSOR::set_value. + +* Clean up allocation of LSM chunk IDs. + +* Update bloom_get so that it doesn't hold a cursor position. + +* Respect the page size for fixed-length column stores, remembering there + are 8 bits per byte. + +* Support bulk loading a bitmap into a fixed-length column store, update + Bloom filter code to use this. + +* Add an example program, ex_test_perf, to demonstrate basic LSM usage. + +* Add a new statistics cursor type "statistics:lsm". Update ex_stat.c to + demonstrate usage. + +* Add a statistics_fast flag to file statistics cursors. Update LSM + statistics so that they aggregate some cache statistics. Add ability to + open a statistics cursor on a checkpoint. + +* Walk a constant number of pages for LRU eviction. + +* Move the cache full check to after an update operation completes, when it + is no longer holding hazard references. This improves behavior with + small caches. + + WiredTiger release 1.3.2, 2012-10-03 ------------------------------------ @@ -1,6 +1,6 @@ -WiredTiger 1.3.2: (October 3, 2012) +WiredTiger 1.3.3: (October 11, 2012) -This is version 1.3.2 of WiredTiger. +This is version 1.3.3 of WiredTiger.
