Abstract: A dynamic proxy may be implemented for a database that can establish a connection between the proxy and a database engine to perform a database queries received from a client at the proxy. The proxy may receive a connection request (and later database queries) through a first network endpoint from a client. The proxy can then determine based on the source of the connection request a second network endpoint through which to access the database (e.g., the endpoint of the database engine). Once the proxy establishes a connection with the database engine through the second network endpoint, the proxy can request the performance of queries at the database engine instead of the client.

Abstract: Proxy-based scaling may be performed for databases. A proxy may be implemented for a database that can establish a connection between the proxy and a database engine to perform a database queries received from a client at the proxy. A scaling event may be detected for the database responsive to which the proxy may establish a connection with a new database engine which may, in some embodiments, have different capabilities or resources that address the features or criteria that triggered the scaling event. Session state may be copied from the database engine to the new database engine so that the new database engine may be able to provide access to the database on behalf of requests received from the client through the proxy.

Abstract: Systems and techniques are disclosed for multiplexing database connections with a database proxy, in association with prepared statements. When a client sends initial messages, via a client connection, that set up a prepared statement with a database, the database proxy stores corresponding prepared statement setup data in state data associated with the client connection. When the client sends subsequent messages via the client connection that invoke the prepared statement, the database proxy selects a database connection to use to forward the subsequent messages to the database. The database proxy uses the stored prepared statement setup data to select a database connection that the database already associates with the prepared statement, or to inject prepared statement setup messages that cause the database to set up the prepared statement with the selected database connection.
