Struct aws_sdk_rds::model::ConnectionPoolConfigurationInfo

#[non_exhaustive]
pub struct ConnectionPoolConfigurationInfo { /* private fields */ }

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

Implementations

impl ConnectionPoolConfigurationInfo

pub fn max_connections_percent(&self) -> i32

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.

pub fn max_idle_connections_percent(&self) -> i32

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.

pub fn connection_borrow_timeout(&self) -> i32

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.

pub fn session_pinning_filters(&self) -> Option<&[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.

pub fn init_query(&self) -> Option<&str>

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 single SET statement, such as SET x=1, y=2.

impl ConnectionPoolConfigurationInfo

pub fn builder() -> Builder

Creates a new builder-style object to manufacture ConnectionPoolConfigurationInfo.

Trait Implementations

impl Clone for ConnectionPoolConfigurationInfo

fn clone(&self) -> ConnectionPoolConfigurationInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectionPoolConfigurationInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<ConnectionPoolConfigurationInfo> for ConnectionPoolConfigurationInfo

fn eq(&self, other: &ConnectionPoolConfigurationInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
