Claim 3:
4. A computer-implemented method comprising:
receiving, at a query processing service of a provider network, an endpoint configuration request to create a web service endpoint to a target database instance within the provider network, the endpoint configuration request comprising an identifier of the target database instance;
creating the web service endpoint to the target database instance;
configuring the web service endpoint to the target database instance;
receiving, at the web service endpoint to the target database instance, a query request originated by a client and comprising a Hyper Text Transfer Protocol (HTTP) message carrying a payload comprising a statement to be executed by the target database instance within the provider network, wherein the target database instance is a relational database;
identifying, by the query processing service, an existing connection to the target database instance by determining an association of the web service endpoint to a first connection pool server in a set of connection pool servers that connects to a plurality of target database instances, the plurality of target database instances including the target database instance;
transmitting the statement for execution at the target database instance via the existing connection;
obtaining a query result based on the execution of the statement; and
transmitting a query response to the client, wherein the query response is based on the query result.
