The following ``modify-db-proxy-target-group`` example modifies a DB proxy target group to set the maximum connections to 80 percent and maximum idle connections to 10 percent. ::

    aws rds modify-db-proxy-target-group \
        --target-group-name default \
        --db-proxy-name proxyExample \
        --connection-pool-config MaxConnectionsPercent=80,MaxIdleConnectionsPercent=10
