* SERVER-40939 [FLE] Changes to enable $lookupPawel Terlecki2019-05-311-0/+7
| | | | | | Map instead deque is used to enable proper initialization of sub-pipelines. Accessors added to DocumentSourceLookup to implement support in Agg for FLE.

| | | | encryption in agg
* SERVER-40056 Remove partial implementation of streaming $group.David Storch2019-03-111-27/+0
| | | | | | The streaming $group optimization was never fully implemented, so the code was disabled. This patch removes the dead code, including DocumentSource::getOutputSorts().
* SERVER-38360 Prevent $out writing to ns read from in the same pipelineCharlie Swanson2019-02-141-2/+5
| | | | | This restriction only applies to $out with modes "insertDocuments" and "replaceDocuments".
* SERVER-39560 - remove leading blank line on all C++ filesBilly Donahue2019-02-131-1/+0
| | | | | | Remove leading comments that are just stating the filename. Move any file-level comments below the copyright banner. Remove leading blank lines.
* SERVER-38311 Change out merging strategyCharlie Swanson2019-02-131-55/+39
| | | | | 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.
* Revert " SERVER-38311 Adjust $out merging strategy"Charlie Swanson2019-01-161-40/+55
| | | | This reverts commit 0cb2195939494660334db8e9d0a52509caeb621c.

* SERVER-35419 $lookup and $facet must inherit constraints from childrenKyle Suarez2018-09-141-211/+1
| | | | | | | | By default, $lookup and $facet do not write persistent data and are allowed in a transaction. However, both stages must inherit the "strictest" disk use requirement of any stage in their sub-pipelines, and can only be used in a transaction if each of those pipelines contain only transaction-compatible stages.
* SERVER-35905 Add logic to detect when $out is eligible for an exchangeCharlie Swanson2018-08-241-0/+18
|
* SERVER-33323 Refactor agg cursor merging on mongosCharlie Swanson2018-08-151-5/+21
| | | | | | | | | | 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-35043, SERVER-22949: move geoNear implementation into aggregationKyle Suarez2018-06-181-1/+1
| | | | | | | | | | This commit removes the geoNear command and moves its implementation into the aggregation framework. Users should use the aggregate command with a $geoNear stage. The implementation rewrite additionally removes the limit in the $geoNear aggregation stage. To limit the number of results, use a $limit stage.

* SERVER-31289 Add test only $listLocalCursorsJason Carey2017-10-031-1/+12
| | | | | | | In order to make the kill sessions test a bit more reliable, adding a test only agg stage that returns minimal info about cursors. That way we can see if we killed our specific cursors, rather than looking at global counts.
