MongoDB is an open-source document database that provides high performance, high availability, and easy scalability. .PP 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. .PP Here are some resources for learning more about MongoDB: .IP "\(bu" 4 MongoDB Manual .IP "\(bu" 4 MongoDB \s-1CRUD\s0 Introduction .IP "\(bu" 4 MongoDB Data Modeling Introductions .PP To get started with the Perl driver, see these pages: .IP "\(bu" 4 MongoDB Perl Driver Tutorial .IP "\(bu" 4 MongoDB Perl Driver Examples .PP Extensive documentation and support resources are available via the MongoDB community website . .SH "USAGE" .IX Header "USAGE" The MongoDB driver is organized into a set of classes representing different levels of abstraction and functionality. .PP 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. .PP From a database object, you can get a MongoDB::Collection object for \s-1CRUD\s0 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. .PP See the documentation of those classes for more details or the MongoDB Perl Driver Tutorial for an example. .SS "Error handling" .IX Subsection "Error handling" Unless otherwise documented, errors result in fatal exceptions. See MongoDB::Error for a list of exception classes and error code constants. .SH "METHODS" .IX Header "METHODS" .SS "connect" .IX Subsection "connect" .Vb 3 \& $client = MongoDB\->connect(); # localhost, port 27107 \& $client = MongoDB\->connect($host_uri); \& $client = MongoDB\->connect($host_uri, $options); .Ve .PP This function returns a MongoDB::MongoClient object. The first parameter is used as the \f(CW\*(C`host\*(C'\fR argument and must be a host name or connection string \&\s-1URI\s0. The second argument is optional. If provided, it must be a hash reference of constructor arguments for MongoDB::MongoClient::new. .PP If an error occurs, a MongoDB::Error object will be thrown. .PP \&\fB\s-1NOTE\s0\fR: To connect to a replica set, a replica set name must be provided. For example, if the set name is \*(L"setA\*(R": .PP .Vb 1 \& $client = MongoDB\->connect("mongodb://example.com/?replicaSet=setA"); .Ve .SH "SEMANTIC VERSIONING SCHEME" .IX Header "SEMANTIC VERSIONING SCHEME" Starting with MongoDB \f(CW\*(C`v1.0.0\*(C'\fR, the driver reverts to the more familiar three-part version-tuple numbering scheme used by both Perl and MongoDB: \&\f(CW\*(C`vX.Y.Z\*(C'\fR .IP "\(bu" 4 \&\f(CW\*(C`X\*(C'\fR will be incremented for incompatible \s-1API\s0 changes. .IP "\(bu" 4 Even-value increments of \f(CW\*(C`Y\*(C'\fR indicate stable releases with new functionality. \f(CW\*(C`Z\*(C'\fR will be incremented for bug fixes. .IP "\(bu" 4 Odd-value increments of \f(CW\*(C`Y\*(C'\fR indicate unstable (\*(L"development\*(R") releases that should not be used in production. \f(CW\*(C`Z\*(C'\fR increments have no semantic meaning; they indicate only successive development releases. .PP See the Changes file included with releases for an indication of the nature of changes involved. .SH "ENVIRONMENT VARIABLES" .IX Header "ENVIRONMENT VARIABLES" If the \f(CW\*(C`PERL_MONGO_WITH_ASSERTS\*(C'\fR 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. .SH "SUPPORT" .IX Header "SUPPORT" .SS "Bugs / Feature Requests" .IX Subsection "Bugs / Feature Requests" Please report any bugs or feature requests through the issue tracker at .
