Class: Mongo::URI::SRVProtocol

Inherits:
Mongo::URI show all
Defined in:
lib/mongo/uri/srv_protocol.rb

Overview

Parser for a URI using the mongodb+srv protocol, which specifies a DNS to query for SRV records. The driver will query the DNS server for SRV records on hostname.domainname, prefixed with _mongodb._tcp The SRV records can then be used as the seedlist for a Mongo::Client. The driver also queries for a TXT record providing default connection string options. Only one TXT record is allowed, and only a subset of Mongo::Client options is allowed.

Please refer to the Initial DNS Seedlist Discovery spec for details.

github.com/mongodb/specifications/blob/master/source/initial-dns-seedlist-discovery

Examples:

Use the uri string to make a client connection.

client = Mongo::Client.new('mongodb+srv://test6.test.build.10gen.cc/')

Instance Method Details

#client_options ⇒ Hash

Gets the options hash that needs to be passed to a Mongo::Client on instantiation, so we don’t have to merge the txt record options, credentials, and database in at that point - we only have a single point here.

Examples:

Get the client options.

uri.client_options

Returns:

  • (Hash) —

    The options passed to the Mongo::Client
