Overview
27+
--------
28+
29+
In this guide, you can learn how to use the {+driver-short+} to perform
30+
**aggregation operations**.
31+
32+
Aggregation operations process data in your MongoDB collections and
33+
return computed results. The MongoDB Aggregation framework, which is
34+
part of the Query API, is modeled on the concept of data processing
35+
pipelines. Documents enter a pipeline comprised of one or more stages,
36+
and this pipeline transforms the documents into an aggregated result.
37+
38+
An aggregation operation is similar to a car factory. A car factory has
39+
an assembly line, which contains assembly stations with specialized
40+
tools to do specific jobs, like drills and welders. Raw parts enter the
41+
factory, and then the assembly line transforms and assembles them into a
42+
finished product.
43+
44+
The **aggregation pipeline** is the assembly line, **aggregation
45+
stages** are the assembly stations, and **operator expressions** are the
46+
specialized tools.
47+
48+
For more information about aggregation in the {+driver-short+}, see the
49+
following pages:
50+
51+
- :ref:`<java-aggregation-expression-operations>`
52+
- :ref:`<java-aggregation-examples>`
53+
54+
Compare Aggregation and Find Operations
55+
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
56+
57+
You can use find operations to perform the following actions:
58+
59+
- Select *what* documents to return
60+
- Select *what* fields to return
61+
- Sort the results
62+
63+
You can use aggregation operations to perform the following actions:
64+
65+
- Perform find operations
66+
- Rename fields
67+
- Calculate fields
68+
- Summarize data
69+
- Group values
70+
71+
Aggregation operations have some :manual:`limitations </core/aggregation-pipeline-limits/>` you must keep in mind:
72+
73+
- Returned documents must not violate the :manual:`BSON document size limit </reference/limits/#mongodb-limit-BSON-Document-Size>`
74+
of 16 megabytes.
75+
76+
- Pipeline stages have a memory limit of 100 megabytes by default. If required, you can exceed this limit by using
77+
the `allowDiskUse <{+api+}/apidocs/mongodb-driver-sync/com/mongodb/client/AggregateIterable.html#allowDiskUse(java.lang.Boolean)>`__
78+
method.
79+
80+
.. important:: ``$graphLookup`` exception
81+
82+
The :manual:`$graphLookup </reference/operator/aggregation/graphLookup/>` stage has a strict memory limit of 100 megabytes
83+
and will ignore ``allowDiskUse``.
