Overview
Displays the settings that control the size and behavior of the
connection pool associated with a DBProxyTarget
.

-
#connection_borrow_timeout ⇒ Integer
The number of seconds for a proxy to wait for a connection to become available in the connection pool.
-
#init_query ⇒ String
One or more SQL statements for the proxy to run when opening each new database connection.
-
#max_connections_percent ⇒ Integer
The maximum size of the connection pool for each target in a target group.
-
#max_idle_connections_percent ⇒ Integer
Controls how actively the proxy closes idle database connections in the connection pool.
-
#session_pinning_filters ⇒ Array<String>
Each item in the list represents a class of SQL operations that normally cause all later statements in a session using a proxy to be pinned to the same underlying database connection.
Instance Attribute Details
#connection_borrow_timeout ⇒ Integer
The number of seconds for a proxy to wait for a connection to become available in the connection pool. Only applies when the proxy has opened its maximum number of connections and all connections are busy with client sessions.

#init_query ⇒ String
One or more SQL statements for the proxy to run when opening each
new database connection. The setting is typically used with SET
statements to make sure that each connection has identical settings.
The query added here must be valid. For including multiple variables
in a single SET statement, use a comma separator. This is an
optional field.
For example: SET variable1=value1, variable2=value2
Since you can access initialization query as part of target group configuration, it is not protected by authentication or cryptographic methods. Anyone with access to view or manage your proxy target group configuration can view the initialization query. You should not add sensitive data, such as passwords or long-lived encryption keys, to this option.

#max_connections_percent ⇒ Integer
The maximum size of the connection pool for each target in a target
group. The value is expressed as a percentage of the
max_connections
setting for the RDS DB instance or Aurora DB
cluster used by the target group.

#max_idle_connections_percent ⇒ Integer
Controls how actively the proxy closes idle database connections in
the connection pool. The value is expressed as a percentage of the
max_connections
setting for the RDS DB instance or Aurora DB
cluster used by the target group. With a high value, the proxy
leaves a high percentage of idle database connections open. A low
value causes the proxy to close more idle connections and return
them to the database.

#session_pinning_filters ⇒ Array<String>
Each item in the list represents a class of SQL operations that
normally cause all later statements in a session using a proxy to be
pinned to the same underlying database connection. Including an item
in the list exempts that class of SQL operations from the pinning
behavior. This setting is only supported for MySQL engine family
databases. Currently, the only allowed value is
EXCLUDE_VARIABLE_SETS
.
