Data Source Cursors

NOTE: This section describes the Result Set Cache node in Settings & Diagnostics (Administration application). This node is reserved for use by Technical Support.

The result set is the data returned from a data source that is executing a read. The data server can provide that data to clients in a piecemeal fashion. Cursors provide the ability to send partial result sets to the client and send the rest of the results on an as-needed basis. This is transparent to the client and the data source.

The following information is provided on the Result Set Cache node:
