NAME
MongoDB - Official MongoDB Driver for Perl
VERSION
version v1.2.2
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.
