Title
(EN) BEST-EFFORTS DATABASE FUNCTIONS
(ZH) 尽力而为数据库功能
Abstract
(EN)
A computer-implemented method and system at a network switch provides using one or more processors to perform a pre-defined database function on query data contained in data messages received at the network switch, with the performing producing result data, and wherein the pre-defined database function is performed on the query data in a first mode of operation to a state of full completion, generating complete result data and no skipped query data, and in a second mode of operation to a state of partial completion, generating partially complete result data and skipped query data. Further, themethod and system performing one or more network switch functions to route the complete result data, and/or route the partially complete result data and skipped query data, to one or more destinationnodes. In addition, an application programming interface (API) is used to define the database function.
