6 MongoDB - Official MongoDB Driver for Perl (EOL)
7
9 version v2.2.2
10
12 Version v2.2.0 was the final feature release of the MongoDB Perl driver
13 and version v2.2.2 is the final patch release.
14 As of August 13, 2020, the MongoDB Perl driver and related libraries
16 have reached end of life and are no longer supported by MongoDB. See
17 the August 2019 deprecation notice
18 <https://www.mongodb.com/blog/post/the-mongodb-perl-driver-is-being-
19 deprecated> for rationale.
20 If members of the community wish to continue development, they are
22 welcome to fork the code under the terms of the Apache 2 license and
23 release it under a new namespace. Specifications and test files for
24 MongoDB drivers and libraries are published in an open repository:
25 mongodb/specifications
26 <https://github.com/mongodb/specifications/tree/master/source>.
27
29 use MongoDB;
30 my $client = MongoDB->connect('mongodb://localhost');
32 my $collection = $client->ns('foo.bar'); # database foo, collection bar
33 my $result = $collection->insert_one({ some => 'data' });
34 my $data = $collection->find_one({ _id => $result->inserted_id });
35
37 This is the official Perl driver for MongoDB <http://www.mongodb.com>.
38 MongoDB is an open-source document database that provides high
39 performance, high availability, and easy scalability.
40 A MongoDB server (or multi-server deployment) hosts a number of
42 databases. A database holds a set of collections. A collection holds a
43 set of documents. A document is a set of key-value pairs. Documents
44 have dynamic schema. Using dynamic schema means that documents in the
45 same collection do not need to have the same set of fields or
46 structure, and common fields in a collection's documents may hold
47 different types of data.
48 Here are some resources for learning more about MongoDB:
50 • MongoDB Manual <http://docs.mongodb.org/manual/contents/>
52 • MongoDB CRUD Introduction
54 <http://docs.mongodb.org/manual/core/crud-introduction/>
55 • MongoDB Data Modeling Introductions
57 <http://docs.mongodb.org/manual/core/data-modeling-introduction/>
58 To get started with the Perl driver, see these pages:
60 • MongoDB Perl Driver Tutorial
62 • MongoDB Perl Driver Examples
64 Extensive documentation and support resources are available via the
66 MongoDB community website <http://www.mongodb.org/>.
67
69 The MongoDB driver is organized into a set of classes representing
70 different levels of abstraction and functionality.
71 As a user, you first create and configure a MongoDB::MongoClient object
73 to connect to a MongoDB deployment. From that client object, you can
74 get a MongoDB::Database object for interacting with a specific
75 database.
76 From a database object, you can get a MongoDB::Collection object for
78 CRUD operations on that specific collection, or a MongoDB::GridFSBucket
79 object for working with an abstract file system hosted on the database.
80 Each of those classes may return other objects for specific features or
81 functions.
82 See the documentation of those classes for more details or the MongoDB
84 Perl Driver Tutorial for an example.
85 MongoDB::ClientSession objects are generated from a
87 MongoDB::MongoClient and allow for advanced consistency options, like
88 causal-consistency and transactions.
89 Error handling
91 Unless otherwise documented, errors result in fatal exceptions. See
92 MongoDB::Error for a list of exception classes and error code
93 constants.
94
96 connect
97 $client = MongoDB->connect(); # localhost, port 27107
98 $client = MongoDB->connect($host_uri);
99 $client = MongoDB->connect($host_uri, $options);
100 This function returns a MongoDB::MongoClient object. The first
102 parameter is used as the "host" argument and must be a host name or
103 connection string URI. The second argument is optional. If provided,
104 it must be a hash reference of constructor arguments for
105 MongoDB::MongoClient::new.
106 If an error occurs, a MongoDB::Error object will be thrown.
108 NOTE: To connect to a replica set, a replica set name must be provided.
110 For example, if the set name is "setA":
111 $client = MongoDB->connect("mongodb://example.com/?replicaSet=setA");
113
115 The driver has been tested against MongoDB versions 2.6 through 4.2.
116 All features of these versions are supported, except for field-level
117 encryption. The driver may work with future versions of MongoDB, but
118 will not include support for new MongoDB features and should be
119 thoroughly tested within applications before deployment.
120
122 Starting with MongoDB "v1.0.0", the driver reverts to the more familiar
123 three-part version-tuple numbering scheme used by both Perl and
124 MongoDB: "vX.Y.Z"
125 • "X" will be incremented for incompatible API changes.
127 • Even-value increments of "Y" indicate stable releases with new
129 functionality. "Z" will be incremented for bug fixes.
130 • Odd-value increments of "Y" indicate unstable ("development")
132 releases that should not be used in production. "Z" increments
133 have no semantic meaning; they indicate only successive development
134 releases.
135 See the Changes file included with releases for an indication of the
137 nature of changes involved.
138
140 If the "PERL_MONGO_WITH_ASSERTS" environment variable is true before
141 the MongoDB module is loaded, then its various classes will be
142 generated with internal type assertions enabled. This has a severe
143 performance cost and is not recommended for production use. It may be
144 useful in diagnosing bugs.
145 If the "PERL_MONGO_NO_DEP_WARNINGS" environment variable is true, then
147 deprecated methods will not issue warnings when used. (Normally, a
148 deprecation warning is issued once per call-site for deprecated
149 methods.)
150
152 Per threads documentation, use of Perl threads is discouraged by the
153 maintainers of Perl and the MongoDB Perl driver does not test or
154 provide support for use with threads.
