Especifica opciones de conexión

Overview

Esta sección describe la conexión de MongoDB y las opciones de autenticación disponibles en el controlador Ruby. Puede configurar su conexión mediante el URI de conexión (también llamado cadena de conexión) o pasando argumentos a la Mongo::Client constructor.

Uso de la URI de conexión

Si pasa una URI de conexión al constructor Mongo::Client, puede incluir opciones de conexión en la cadena como pares <name>=<value>. En el siguiente ejemplo, la URI de conexión contiene la opción connectTimeoutMS con un valor de 60000 y la opción tls con un valor de true:

uri = "mongodb://<hostname>:<port>/?connectTimeoutMS=60000&tls=true"
client = Mongo::Client.new(uri)

Usando un Mongo::Client

Puede pasar opciones de conexión como argumentos al constructor Mongo::Client en lugar de incluirlas en la URI de conexión. Al configurar la conexión de esta manera, le resultará más fácil cambiar la configuración en tiempo de ejecución y detectar errores durante la compilación. El siguiente ejemplo muestra cómo usar el constructor Mongo::Client para configurar las opciones de conexión:

uri = "mongodb://<hostname>:<port>"
client = Mongo::Client.new(uri, connect_timeout: 60000, ssl: true)

Opciones de conexión

Las siguientes secciones describen las opciones de conexión disponibles en el controlador Ruby.

Compresión de la red

Opción de conexión	Descripción
:compresores	A list of potential compressors to use, in order of preference. The driver chooses the first compressor that is also supported by the server. Currently the driver only supports `zstd`, `snappy`, and `zlib`. Data Type: `Array<String>` Default: none Client Example: `compressors: ['snappy', 'zstd', 'zlib']` Connection URI Example: `compressors=snappy,zstd,zlib`
:nivel de compresión zlib	The Zlib compression level to use, if using compression. This option accepts an integer value between `-1` and `9`: - -1: zlib uses its default compression level (usually `6`). - 0: No compression. - 1: Fastest speed but lowest compression. - 9: Best compression but slowest speed. For more information, see Ruby's ZLib module documentation. Data Type: `Integer` Default: `None` Client Example: `zlib_compression_level: 3` Connection URI Example: `zlibCompressionLevel=3`

:compresores

A list of potential compressors to use, in order of preference.
The driver chooses the first compressor that is also supported
by the server. Currently the driver only supports zstd, snappy, and zlib.

Data Type: Array<String>
Default: none
Client Example: compressors: ['snappy', 'zstd', 'zlib']
Connection URI Example: compressors=snappy,zstd,zlib

:nivel de compresión zlib

The Zlib compression level to use, if using compression.
This option accepts an integer value between -1 and 9:

- -1: zlib uses its default compression level (usually 6).
- 0: No compression.
- 1: Fastest speed but lowest compression.
- 9: Best compression but slowest speed.

For more information, see Ruby's ZLib module
documentation.

Data Type: Integer
Default: None
Client Example: zlib_compression_level: 3
Connection URI Example: zlibCompressionLevel=3

Tiempos de espera

Opción de conexión	Descripción
:tiempo de espera de conexión	The number of seconds to wait to establish a socket connection before raising an exception. This timeout is also used for SRV DNS record resolution. `nil` and `0` mean no timeout. Client creation will fail with an error if an invalid timeout value is passed (such as a negative value or a non-numeric value). Data Type: `Float` Default: `10.0` Client Example: `connect_timeout: 10.0` Connection URI Example: `connectTimeoutMS=10000`
:tiempo de espera_ms	The number of milliseconds to wait for an operation to execute before raising an exception. `0` means no timeout. Client creation will fail with an error if an invalid timeout value is passed (such as a negative value or a non-numeric value). Data Type: `Integer` Default: none Client Example: `timeout_ms: 5000` Connection URI Example: `timeoutMS=5000`

:tiempo de espera de conexión

The number of seconds to wait to establish a socket
connection before raising an exception. This
timeout is also used for SRV DNS record resolution.

nil and 0 mean no timeout. Client creation will
fail with an error if an invalid timeout value
is passed (such as a negative value or a non-numeric value).

Data Type: Float
Default: 10.0
Client Example: connect_timeout: 10.0
Connection URI Example: connectTimeoutMS=10000

:tiempo de espera_ms

The number of milliseconds to wait for an operation to execute
before raising an exception.

0 means no timeout. Client creation will fail
with an error if an invalid timeout value is passed
(such as a negative value or a non-numeric value).

Data Type: Integer
Default: none
Client Example: timeout_ms: 5000
Connection URI Example: timeoutMS=5000

Selección de servidores

Opción de conexión	Descripción
:balanceo de carga	Whether to expect to connect to a load balancer. Data Type: `Boolean` Default: `false` Client Example: `load_balanced: { true }` Connection URI Example: N/A
:server_selection_timeout	The maximum amount of time, in seconds, the driver waits for server selection to succeed before throwing an exception. Data Type: `Integer` Default: `30` Client Example: `server_selection_timeout: 30` Connection URI Example: `serverSelectionTimeoutMS=30000`

Para obtener más información sobre la selección del servidor, consulte la Guíade selección de servidores.

Autenticación

Opción de conexión	Descripción
:mecánica de autenticación	The mechanism that the Ruby driver uses to authenticate the application. Data Type: `Symbol` Default: `:scram256` `nil` if user credentials are not supplied. Client Example: `auth_mech: :scram256` Connection URI Example: `authMechanism=SCRAM-SHA-256`
