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

Properties
- connectionBorrowTimeout → int?
-
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.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- initQuery → String?
-
One or more SQL statements for the proxy to run when opening each new
database connection. Typically used with
SET
statements to make sure that each connection has identical settings such as time zone and character set. This setting is empty by default. For multiple statements, use semicolons as the separator. You can also include multiple variables in a singleSET
statement, such asSET x=1, y=2
.final - maxConnectionsPercent → int?
-
The maximum size of the connection pool for each target in a target group.
For Aurora MySQL, it is expressed as a percentage of the
max_connections
setting for the RDS DB instance or Aurora DB cluster used by the target group.final - maxIdleConnectionsPercent → int?
-
Controls how actively the proxy closes idle database connections in the
connection pool. A high value enables the proxy to leave a high percentage
of idle connections open. A low value causes the proxy to close idle client
connections and return the underlying database connections to the connection
pool. For Aurora MySQL, it is expressed as a percentage of the
max_connections
setting for the RDS DB instance or Aurora DB cluster used by the target group.final - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
sessionPinningFilters
→ List<
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. Currently, the only
allowed value is
EXCLUDE_VARIABLE_SETS
.final
Methods

noSuchMethod(
Invocation invocation) → dynamic -
