slaveOk bit ignored for unsharded aggregate
memory leak in MutableDocument::setNestedFieldSERVER-12132
Value::coerceToString() shouldn't unconditionally construct a stringstream
Fix all uses of shared_ptr<BSONObj>SERVER-9840
Add variables, $$ROOT and $$CURRENT to aggregation and make $let to set them
$map expression to run a sub expression on every member of an array.
Memory check for aggregation via a mongos running on 32 bit linux seems to be wrong
Use new Sorter for Aggregation $sort and $groupSERVER-5932
support cursor based aggregation
$group does not track memory usage
ExpressionNary (and others) do not properly serialize constant expressions, can cause a valid expression on mongos to be unparsable or incorrect on shards.
Include field name and type for $unwind error
Extend document expression language in aggregation to support advanced document filtering.
Extend Aggregation Query Language to Support Complex Redactions
Aggregation cursor needs to not error if a large object is in first batch
improve aggregation framework concurrency implementation
Passing impossible value to skip on aggregation framework causes mongo to exit with out of memory
aggregation: support $out on a sharded cluster
Set operations for Aggregation Framework $project
need a $literal operator to help prevent injection attacks
aggregation: unsharded support $out
Change aggregate shell helper to return cursor.
if a replicaset member goes down during a $out we are left with an inconsistent state
$out and capped collections should probably error
Remove outputNs from agg return object
Secondaries execute distinct/aggregate commands irrespective of slaveOk bit
Optimize simple aggregations using $redact followed by a $match
Redact pipeline not including non-object array members
make $cond accept object as argument
string constants prevent optimization of non string sensitive operators
$and and $or expressions may not short circuit non constants and optimize to a constant if the original expression has only one constant
In $group allow "$$ROOT" to expand to the whole document matched.
sharded aggregation explain failure
Date operators incorrectly throw exceptions for object arguments
aggregation: need an expression to give the size of an array in projections
aggregation: need an explain facility
Change Variables implementation in agg to not use string lookup at runtime.
Aggregation command returning a document close to the maximum size fails.
testshard1.js failing in aggregation and aggregation_auth suites on debug builds
aggregate helper fails against old server versions (unrecognized field "cursor"
listCommands outdated help for aggregate command
Perf : merge consecutive calls to $match
DBCommandCursor missing help() method
Fix required privileges for aggregation with $out.
aggregation: optimize $sort on sharded setup to do a proper merge on mongos
Use documentFromBsonWithDeps in agg again
ShardFilterStage needs to grab metadata at construction rather than first iteration
Aggregation explain plan returns non-boolean 'isMultiKey' value
Typo in aggregation error message for undefined variables: 'undefinded'
Replace PipelineCursor with PipelineRunner
