Significant changes include: + +Changes relevant for upgrading applications: + +Update the table create API to disable prefix compression by default. +Applications generally see better performance without prefix compression, +choosing space saving over performance is up to the application. [#981] + +Change the default leaf_page_max setting from 1MB to 32KB. Choosing a large +default leaf_page_max led to poor performance in out of cache workloads. + +Remove the "--enable-debug" option to configure. It is more standard to set +CFLAGS="-g" variable instead. + +Save the wiredtiger_open configuration when a database is created, so that +settings like cache size, extensions and logging are set consistently by all +subsequent users of the database. + +Add an "--enable-verbose" option to configure. In order to access the verbose +message functionality available as part of the wiredtiger_open and +WT_CONNECTION::reconfigure APIs, it is necessary to pass the --enable-verbose +option to configure. + +Enhance the metadata cursor implementation (i.e: cursors created with a +"metadata:" prefix) so that they can be used to inspect metadata for internal +tables and now support altering the metadata. Add a new "read_only" flag to +cursor configuration that defaults to false for metadata cursors. + +Fix several bugs in raw compression, including one that could cause data +corruption and some that triggered poor performance. +[#984][#991][#1007][#1008][#1013] + +Improve the performance of recovery - we no longer need to scan all log files +looking for the last checkpoint. + +Improve performance of read-only transactions, by deferring the allocation +of transaction IDs. [#978] + +Several bug fixes in hot backup related to log +files, including: + * Always choose the right metadata version in the backup [#972] + * Don't require that hot backup copies log files in order [#976] + * Always copy log files before data files [#976] + * Fix a bug where recovery returned an error if the last log record was + incomplete [#994] + +Speed up checkpoints by doing a better job of skipping pages that can't +contain changes that need to be included. [#954][#963][#1001] + +Add ability to store zero length data items into LSM trees. [#540] + +Add an asynchronous data access/manipulation API to WiredTiger. [#933] + +Add the ability to configure multiple eviction server threads, to help with +keeping space available in the cache. [#918] + +Add the ability to reconfigure the checkpoint and statistics log servers. +[#997][#1004] + +Improve the performance of retrieving data for in cache workloads. [#970] + +Improve the structure of the in-memory tree we are generating, by allowing +internal pages to be split. This significantly improves query performance +in some workloads. [#876] + +Work around a bug in posix_fallocate on Linux, where it could corrupt already +written data. + +Add the ability to leak memory on connection close via new leak_memory option +to WT_CONNECTION::close API. This allows for faster shutdown if a process is +going to exit when the WiredTiger connection is closing. + +Allow salvage to run on any table type. + WiredTiger release 2.1.2, 2014-03-27 ------------------------------------ @@ -1,6 +1,6 @@ -WiredTiger 2.1.3: (March 28, 2014) +WiredTiger 2.2.0: (May 21, 2014) -This is version 2.1.3 of WiredTiger. +This is version 2.2.0 of WiredTiger.
