2021-01-29SERVER-53982 RecordId supports ObjectId typeLouis Williams
Allow RecordId to store either an int64_t or ObjectId. This type is compact and cheap to copy. It assumes that callers who attempt to observe the underlying data are aware of its underlying type.
2020-02-05SERVER-45854 Hold WorkingSetMembers at a distance for sorting.David Storch
This change improves the performance of blocking sort operations executed in the PlanStage layer using the SortStage.

2019-09-26SERVER-43629 Improve Document/Value performanceMartin Neupauer
2019-09-13SERVER-42979 Implement WorkingSet::extract() and WorkingSet::emplace().David Storch
Also replaces WorkingSetMember::isSuspicious with a scheme that associates a snapshot id with every index key. This is needed because extracted WorkingSetMembers are not discoverable from the WorkingSet, and thus cannot be marked as suspicious in preparation for yield.
2019-09-12SERVER-42981 Make WorkingSetMember compatible for use with the Sorter.David Storch
The bulk of this change is to implement serialization and deserialization routines for WorkingSetMember, so that the Sorter can spill WorkingSetMembers to disk. In addition, this changes the SortExecutor to sort WorkingSetMembers internally as opposed to sorting Documents.

Removes the associated flagForReview() mechanism from WorkingSet.
2018-02-14SERVER-33275 Remove `platform/unordered_`* headersADAM David Alan Martin
These headers date from before C++11 support and the `::mongo::stdx::` namespace. They can be removed and uses of the names therein can be changed to `::mongo::stdx::unordered_`* forms.
2016-06-03SERVER-23114 Move functions involving dotted paths to separate library.Max Hirschhorn
The ability to specify a dotted path (e.g. "a.b") to traverse through embedded objects and array elements isn't defined in the BSON specification and so it doesn't belong in our BSON library. The following functions have been defined within a 'dotted_path_support' namespace and accept an additional BSONObj as their first argument to replace the associated method on the BSONObj class. - extractElementAtPath() is functionally equivalent to BSONObj::getFieldDotted(). - extractElementAtPathOrArrayAlongPath() is functionally equivalent to BSONObj::getFieldDottedOrArray(). - extractAllElementsAlongPath() is functionally equivalent to BSONObj::getFieldsDotted(). - extractElementsBasedOnTemplate() is functionally equivalent to BSONObj::extractFields(). - compareObjectsAccordingToSort() is functionally equivalent to BSONObj::woSortOrder().
2016-02-05SERVER-18826 Rename WorkingSet State Names from LOC to RIDJames Wahlin
Also renamed: * WorkingSetMember::hasLoc() -> WorkingSetMember::hasRecordId * WorkingSetMember::loc -> WorkingSetMember::recordId
2015-08-27SERVER-16444 Only make BSONObj underlying WSM owned if not mmapv1.Max Hirschhorn
Resolves the performance regression with mmapv1 introduced by 764e0c4 where documents were being copied in PlanStages that perform invalidations. Partially reverted changes to DeleteStage and UpdateStage because the document to return is not guaranteed to be owned after makeObjOwnedIfNeeded() is called when running with mmapv1.
2015-08-24SERVER-16444 Copy data in the query subsystem as needed.Max Hirschhorn
A WorkingSetMember in the LOC_AND_OBJ state must be made owned when: 1. Its WorkingSetID is cached across multiple calls to work(). 2. Multiple calls to next(), seekExact(), saveState(), etc. are performed on the same WiredTiger cursor in a single work() call. No longer necessary to always copy data out of WiredTiger buffers.

WiredTiger snapshot change Improves performance for query plans with a blocking stage when using the WiredTiger storage engine. In particular, full text search and geoNear queries should benefit.

Changes: * Documented some contracts * Marked noncopyable classes as such * Changed WorkingSetID to size_t from long * Inlined WorkingSet::get since it is simple and very hot * WorkingSetMembers are now pooled and reused * Stopped using unordered_(map|set) ** _data became a vector with freelist ** _flagged became a bool on each member of _data ** _computed became an embedded array
