 * SQL statement lifecycle for the HTTP endpoint. The request thread

 * reads results and inspects the statement contents to emit logs and
 * metrics. The object is transferred between threads, with no overlapping
 * access.

 * The key extension of an HTTP statement is the use of the HTTP request
