Abstract
A database which receives input from a data streaming application may include in-flight streamed data within the scope of a command which alters database data. Preferably, the streaming application produces data tuples for input to at least one table of the database. A user submitting modify data commands to apply to multiple tuples meeting some specified logical parameters may define the command scope to include in-flight data in the streaming application, causing the database manager to forward the command to the streaming application. A streaming application manager invokes database agents in respective nodes of the streaming application, which identify in-flight data meeting the specified logical parameters of the command, and apply the modify data operation to such data.
