* SERVER-38311 Change out merging strategyCharlie Swanson2019-02-131-6/+4
| | | | | Allows an $out stage to run in parallel on all shards if the target collection is sharded and so is the input collection to the aggregate.

* SERVER-33323 Refactor agg cursor merging on mongosCharlie Swanson2018-08-151-1/+1
| | | | | | | | | | This commit makes it so that aggregations will always use a $mergeCursors as a wrapper around a AsyncResultsMerger, which is new behavior for mongos. As part of this refactor, we can delete the concept of a 'merging presorted' $sort stage (which is now handled by the AsyncResultsMerger) and delete the DocumentSourceRouterAdapter stage which talked to a RouterStageMerge, instead directly using a $mergeCursors stage.

* SERVER-25694 Eliminate race in PlanExecutor cleanup.Charlie Swanson2017-04-131-2/+5
| | | | | | | | | | | Ensures that a collection lock is held in at least MODE_IS while deregistering a PlanExecutor from the cursor manager. Introduces new PlanExecutor::dispose() and ClientCursor::dispose() methods that must be called before destruction of those classes, and ensures they are called before destruction. These calls will thread an OperationContext all the way through to DocumentSource::dispose() for each stage in a Pipeline, which will give DocumentSourceCursor a chance to acquire locks and deregister its PlanExecutor if necessary.
* SERVER-19758 add support for "executionStats" and "allPlansExecution" to agg ↵David Storch2017-03-131-1/+1
| | | | | | | | | | | | | | | | | explain Like other explainable commands, aggregate can now be explained using the explain command, e.g. db.runCommand({explain: {aggregate: ...}, verbosity: "executionStats"}). The existing explain:true flag corresponds to "queryPlanner" mode and is still supported. However, explain:true cannot be specified when explaining aggregate via the explain command. Additional execution information is provided only in the $cursor section of the aggregation explain output. Having aggregation stages themselves track and report execution info is further work.
* SERVER-25535 Remove injectExpressionContext().Charlie Swanson2016-12-161-6/+1
| | | | | | | | | | | | | | | These methods were formally used to propagate a new ExpressionContext to stages, accumulators, or expressions which potentially needed to comparisons. Originally, this was necessary since Pipeline parsing happened outside of the collection lock and thus could not determine if there was a default collation on the collection. This meant that the collation could change after parsing and any operators that might compare strings would need to know about it. We have since moved parsing within the lock, so the collation can be known at parse time and the ExpressionContext should not change. This patch requires an ExpressionContext at construction time, and disallows changing the collation on an ExpressionContext.
* SERVER-25038 add LiteParsedPipelineDavid Storch2016-10-031-1/+17
| | | | | | This provides a way to do pre-parse validity checks. Full parsing of the Pipeline must be done under the collection lock, when the collation is known.
* SERVER-24153 Allow pipelines within $facet stage to process in batches.Charlie Swanson2016-09-011-6/+13
| | | | | This approach removes the need to buffer all documents in memory, thus removing concerns about spilling intermediate results to disk.

* SERVER-24508 DocumentComparator and ValueComparatorDavid Storch2016-07-141-0/+5
| | | | | | | | | | | - Changes the Document/Value library to require comparisons to be made in the context of a comparator object. This is prep work for full collation support in the aggregation system. - Adds injectExpressionContext() to propagate the ExpressionContext containing the comparator object to all DocumentSource, Accumulator, and Expression instances involved in the Pipeline.
