--target-group-name
(string)
The name of the new target group to assign to the proxy.
--db-proxy-name
(string)
The name of the new proxy to which to assign the target group.
--connection-pool-config
(structure)
The settings that determine the size and behavior of the connection pool for the target group.
MaxConnectionsPercent -> (integer)
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.Default: 100
Constraints: between 1 and 100
MaxIdleConnectionsPercent -> (integer)
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.Default: 50
Constraints: between 0 and
MaxConnectionsPercent
ConnectionBorrowTimeout -> (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.
Default: 120
Constraints: between 1 and 3600, or 0 representing unlimited
SessionPinningFilters -> (list)
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.
Default: no session pinning filters
(string)
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. For multiple statements, use semicolons as the separator. You can also include multiple variables in a singleSET
statement, such asSET x=1, y=2
.Default: no initialization query
Shorthand Syntax:
MaxConnectionsPercent=integer,MaxIdleConnectionsPercent=integer,ConnectionBorrowTimeout=integer,SessionPinningFilters=string,string,InitQuery=string
JSON Syntax:
{
"MaxConnectionsPercent": integer,
"MaxIdleConnectionsPercent": integer,
"ConnectionBorrowTimeout": integer,
"SessionPinningFilters": ["string", ...],
"InitQuery": "string"
}
--new-name
(string)
The new name for the modified
DBProxyTarget
. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens; it can’t end with a hyphen or contain two consecutive hyphens.
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
DBProxyTargetGroup -> (structure)
The settings of the modified
DBProxyTarget
.DBProxyName -> (string)
The identifier for the RDS proxy associated with this target group.
TargetGroupName -> (string)
The identifier for the target group. This name must be unique for all target groups owned by your Amazon Web Services account in the specified Amazon Web Services Region.
TargetGroupArn -> (string)
The Amazon Resource Name (ARN) representing the target group.
IsDefault -> (boolean)
Whether this target group is the first one used for connection requests by the associated proxy. Because each proxy is currently associated with a single target group, currently this setting is always
true
.Status -> (string)
The current status of this target group. A status of
available
means the target group is correctly associated with a database. Other values indicate that you must wait for the target group to be ready, or take some action to resolve an issue.ConnectionPoolConfig -> (structure)
The settings that determine the size and behavior of the connection pool for the target group.
MaxConnectionsPercent -> (integer)
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.MaxIdleConnectionsPercent -> (integer)
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.ConnectionBorrowTimeout -> (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.
SessionPinningFilters -> (list)
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
.(string)
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
.CreatedDate -> (timestamp)
The date and time when the target group was first created.
UpdatedDate -> (timestamp)
The date and time when the target group was last updated.
