BurstyPool(target_size=10, labels=None, database_role=None)

Concrete session pool implementation:

• "Pings" existing sessions via session.exists before returning them.

• Creates a new session, rather than blocking, when get is called on an empty pool.

• Discards the returned session, rather than blocking, when put is called on a full pool.

Parameters
Name	Description
target_size	int max pool size
labels	dict (str -> str) or None (Optional) user-assigned labels for sessions created by the pool.
database_role	str (Optional) user-assigned database_role for the session.

Methods

bind

bind(database)

Associate the pool with a database.

Parameter
Name	Description
database	Database database used by the pool to create sessions when needed.

clear

get

get()

Check a session out from the pool.

Returns
Type	Description
Session	an existing session from the pool, or a newly-created session.

put

put(session)

Return a session to the pool.

Never blocks: if the pool is full, the returned session is discarded.

Parameter
Name	Description
session	Session the session being returned.
