builder() |
default java.lang.Number |
getConnectionBorrowTimeout()
The number of seconds for a proxy to wait for a connection to become available in the connection pool.
|
default java.lang.String |
getInitQuery()
One or more SQL statements for the proxy to run when opening each new database connection.
|
default java.lang.Number |
getMaxConnectionsPercent()
The maximum size of the connection pool for each target in a target group.
|
default java.lang.Number |
getMaxIdleConnectionsPercent()
Controls how actively the proxy closes idle database connections in the connection pool.
|
default java.util.List<java.lang.String> |
getSessionPinningFilters()
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.
|
default java.lang.Number getConnectionBorrowTimeout()
Only applies when the proxy has opened its maximum number of connections and all connections are busy with client sessions.
Default: 120
Constraints: between 1 and 3600, or 0 representing unlimited
default java.lang.String getInitQuery()
Typically used with SET
statements to make sure that each connection has identical settings such as time zone and character set. For multiple statements, use semicolons as the separator. You can also include multiple variables in a single SET
statement, such as SET x=1, y=2
.
Default: no initialization query
default java.lang.Number getMaxConnectionsPercent()
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.
Default: 100
Constraints: between 1 and 100
default java.lang.Number getMaxIdleConnectionsPercent()
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.
Default: 50
Constraints: between 0 and MaxConnectionsPercent
default java.util.List<java.lang.String> getSessionPinningFilters()
Including an item in the list exempts that class of SQL operations from the pinning behavior.
Default: no session pinning filters
