class pymongo.pool.PoolOptions¶

Read only connection pool options for an AsyncMongoClient/MongoClient.

Should not be instantiated directly by application developers. Access a client’s pool options via pool_options instead:

pool_opts = client.options.pool_options
pool_opts.max_pool_size
pool_opts.min_pool_size

Parameters:

• max_pool_size (int)

• min_pool_size (int)

• max_idle_time_seconds (Optional[int])

• connect_timeout (Optional[float])

• socket_timeout (Optional[float])

• wait_queue_timeout (Optional[int])

• ssl_context (Optional[SSLContext])

• tls_allow_invalid_hostnames (bool)

• event_listeners (Optional[_EventListeners])

• appname (Optional[str])

• driver (Optional[DriverInfo])

• compression_settings (Optional[CompressionSettings])

• max_connecting (int)

• pause_enabled (bool)

• server_api (Optional[ServerApi])

• load_balanced (Optional[bool])

• credentials (Optional[MongoCredential])

• is_sync (Optional[bool])

property appname: str | None¶

The application name, for sending with hello in server handshake.

property connect_timeout: float | None¶

How long a connection can take to be opened before timing out.

property driver: DriverInfo | None¶

Driver name and version, for sending with hello in handshake.

property load_balanced: bool | None¶

True if this Pool is configured in load balanced mode.

property max_connecting: int¶

The maximum number of concurrent connection creation attempts per pool. Defaults to 2.

property max_idle_time_seconds: int | None¶

The maximum number of seconds that a connection can remain idle in the pool before being removed and replaced. Defaults to None (no limit).

property max_pool_size: float¶

The maximum allowable number of concurrent connections to each connected server. Requests to a server will block if there are maxPoolSize outstanding connections to the requested server. Defaults to 100. Cannot be 0.

When a server’s pool has reached max_pool_size, operations for that server block waiting for a socket to be returned to the pool. If waitQueueTimeoutMS is set, a blocked operation will raise ConnectionFailure after a timeout. By default waitQueueTimeoutMS is not set.

property metadata: dict[str, Any]¶

A dict of metadata about the application, driver, os, and platform.

property min_pool_size: int¶

The minimum required number of concurrent connections that the pool will maintain to each connected server. Default is 0.

property non_default_options: dict[str, Any]¶

The non-default options this pool was created with.

Added for CMAP’s PoolCreatedEvent.

property server_api: ServerApi | None¶

A pymongo.server_api.ServerApi or None.

property socket_timeout: float | None¶

How long a send or receive on a socket can take before timing out.

property tls_allow_invalid_hostnames: bool¶

If True skip ssl.match_hostname.

property wait_queue_timeout: int | None¶

How long a thread will wait for a socket from the pool if the pool has no free sockets.
