=head1 NAME
MongoDB - Official MongoDB Driver for Perl
=head1 VERSION
version v1.3.4
B<NOTE:> The v1.3.x versions are development releases in advance of the
MongoDB Perl Driver v1.4.0. They are available for evaluation and testing
and should not be used in production.
=head1 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 });
=head1 DESCRIPTION
This is the official Perl driver for L<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:

Extensive documentation and support resources are available via the
L<MongoDB community website|http://www.mongodb.org/>.
=head1 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 L<MongoDB::MongoClient> object to
connect to a MongoDB deployment.  From that client object, you can get
a L<MongoDB::Database> object for interacting with a specific database.
From a database object, you can get a L<MongoDB::Collection> object for CRUD
operations on that specific collection, or a L<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
L<MongoDB Perl Driver Tutorial|MongoDB::Tutorial> for an example.
=head2 Error handling
Unless otherwise documented, errors result in fatal exceptions.  See
L<MongoDB::Error> for a list of exception classes and error code
constants.
=head1 METHODS
=head2 connect
    $client = MongoDB->connect(); # localhost, port 27107
    $client = MongoDB->connect($host_uri);
    $client = MongoDB->connect($host_uri, $options);
This function returns a L<MongoDB::MongoClient> object.  The first parameter is
used as the C<host> argument and must be a host name or L<connection string
URI|MongoDB::MongoClient/CONNECTION STRING URI>.  The second argument is
optional.  If provided, it must be a hash reference of constructor arguments
for L<MongoDB::MongoClient::new|MongoDB::MongoClient/ATTRIBUTES>.
If an error occurs, a L<MongoDB::Error> object will be thrown.
B<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");

=head1 SEMANTIC VERSIONING SCHEME
Starting with MongoDB C<v1.0.0>, the driver reverts to the more familiar
three-part version-tuple numbering scheme used by both Perl and MongoDB:
C<vX.Y.Z>
=over 4
=item *
C<X> will be incremented for incompatible API changes.
=item *
Even-value increments of C<Y> indicate stable releases with new functionality.  C<Z> will be incremented for bug fixes.
=item *
Odd-value increments of C<Y> indicate unstable ("development") releases that should not be used in production.  C<Z> increments have no semantic meaning; they indicate only successive development releases.
=back
See the Changes file included with releases for an indication of the nature of
changes involved.
=head1 ENVIRONMENT VARIABLES
If the C<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.
