NAME
MongoDB - Official MongoDB Driver for Perl
VERSION
version v1.8.1
SYNOPSIS
use MongoDB;
my $client = MongoDB->connect('mongodb://localhost');
my $collection = $client->ns('foo.bar'); # database foo, collection bar
my $result = $collection->insert_one({ some => 'data' });
my $data = $collection->find_one({ _id => $result->inserted_id });
DESCRIPTION
This is the official Perl driver for MongoDB <http://www.mongodb.com>. MongoDB is an
open-source document database that provides high performance, high availability, and easy
scalability.
A MongoDB server (or multi-server deployment) hosts a number of databases. A database
holds a set of collections. A collection holds a set of documents. A document is a set of
key-value pairs. Documents have dynamic schema. Using dynamic schema means that documents
in the same collection do not need to have the same set of fields or structure, and common
fields in a collection's documents may hold different types of data.
Here are some resources for learning more about MongoDB:
• MongoDB Manual <http://docs.mongodb.org/manual/contents/>
• MongoDB CRUD Introduction <http://docs.mongodb.org/manual/core/crud-introduction/>
• MongoDB Data Modeling Introductions <http://docs.mongodb.org/manual/core/data-
modeling-introduction/>
To get started with the Perl driver, see these pages:
• MongoDB Perl Driver Tutorial
• MongoDB Perl Driver Examples
Extensive documentation and support resources are available via the MongoDB community
website <http://www.mongodb.org/>.
USAGE
The MongoDB driver is organized into a set of classes representing different levels of
abstraction and functionality.
As a user, you first create and configure a MongoDB::MongoClient object to connect to a
MongoDB deployment. From that client object, you can get a MongoDB::Database object for
interacting with a specific database.
From a database object, you can get a MongoDB::Collection object for CRUD operations on
that specific collection, or a MongoDB::GridFS object for working with an abstract file
system hosted on the database. Each of those classes may return other objects for
specific features or functions.
See the documentation of those classes for more details or the MongoDB Perl Driver
Tutorial for an example.
Error handling
Unless otherwise documented, errors result in fatal exceptions. See MongoDB::Error for a
list of exception classes and error code constants.
METHODS
connect
$client = MongoDB->connect(); # localhost, port 27107
$client = MongoDB->connect($host_uri);
$client = MongoDB->connect($host_uri, $options);
This function returns a MongoDB::MongoClient object. The first parameter is used as the
"host" argument and must be a host name or connection string URI. The second argument is
optional. If provided, it must be a hash reference of constructor arguments for
MongoDB::MongoClient::new.
If an error occurs, a MongoDB::Error object will be thrown.
NOTE: To connect to a replica set, a replica set name must be provided. For example, if
the set name is "setA":
$client = MongoDB->connect("mongodb://example.com/?replicaSet=setA");
SEMANTIC VERSIONING SCHEME
Starting with MongoDB "v1.0.0", the driver reverts to the more familiar three-part
version-tuple numbering scheme used by both Perl and MongoDB: "vX.Y.Z"
• "X" will be incremented for incompatible API changes.
• Even-value increments of "Y" indicate stable releases with new functionality. "Z"
will be incremented for bug fixes.
• Odd-value increments of "Y" indicate unstable ("development") releases that should not
be used in production. "Z" increments have no semantic meaning; they indicate only
successive development releases.
See the Changes file included with releases for an indication of the nature of changes
involved.
ENVIRONMENT VARIABLES
If the "PERL_MONGO_WITH_ASSERTS" environment variable is true before the MongoDB module is
loaded, then its various classes will be generated with internal type assertions enabled.
This has a severe performance cost and is not recommended for production use. It may be
useful in diagnosing bugs.
If the "PERL_MONGO_NO_DEP_WARNINGS" environment variable is true, then deprecated methods
will not issue warnings when used. (Normally, a deprecation warning is issued once per
call-site for deprecated methods.)
THREADS
Because of well-known bugs, use of threads on perls before v5.8.5 is not supported.
