A subset of the information available from the collStats command.
A subset of the information available from the collStats command. Many more fields are available, some only in particular MongoDB versions or with particular storage engines.
count
The number of documents in the collection.
dataSize
The total size "in memory" in bytes of all documents in the collection, not including headers or indexes.

Configuration parameters for MapReduce operations
Configuration parameters for MapReduce operations
map
The mapping function
reduce
The reducing function
selection
Query selector to apply to input documents
inputSort
Criteria to use to sort the input documents.
limit
Limit the number of input documents to map
finalizer
JavaScript function applied to the output after the reduce function.
scope
Global variables made available to the map, reduce and finalizer functions.
jsMode
Whether to avoid converting intermediate values to BSON, leaving them as JavaScript objects instead. Setting this to true has implications on the size of the input, see the MongoDB mapReduce documentation for details.
verbose
Whether to include additional information, such as timing, in the results.

A Workflow is a graph of atomic operations, with WorkflowOps for the vertices.
A Workflow is a graph of atomic operations, with WorkflowOps for the vertices. We crush them down into a WorkflowTask. This crush gives us a location to optimize our workflow decisions. EG, A sequence of simple ops may be combined into a single pipeline request, but if one of those operations contains JS, we have to execute that outside of a pipeline, possibly reordering the other operations to avoid having two pipelines with a JS operation in the middle.
We also implement the optimizations atomic http://docs.mongodb.org/manual/core/aggregation-pipeline-optimization/ so that we can build others potentially on top of them (including reordering non-pipelines around pipelines, etc.).
