EDGE:MY_ACTUAL_STATE​

edge:my_actual_state( ) -> Record
STABLE

The last updated actual state of this edge device.

EDGE:MY_DESIRED_STATE​

edge:my_desired_state( ) -> Record
STABLE

EDGE:RUN​

edge:run( ) -> Charstring
STABLE

EDGE_CQ​

edge_cq(Charstring manager, Vector of Charstring edges, Charstring query, Record opts) -> Stream
STABLE

No description.

edge_cq(Vector of Charstring edges, Charstring cq) -> Stream
STABLE

Broadcast continuous query cq to edges and merge result streams

edge_cq(Vector of Charstring edges, Charstring cq, Record opts) -> Stream
STABLE

No description.

edge_cq(Charstring edge, Charstring cq, Record opts) -> Stream
STABLE

Execute continuous query cq on edge with options opts 

 Options can contain the following fields:

  • store-and-forward: String - name of store-and-foward stream. Used to enable store and forward and to retrieve forwarded data in a later stage. When store and forward is enabled data is buffered for forward-interval number of seconds before attempting to send it to the requesting server. When store and forward is enabled the options buffer-in-memory and buffer-size will both affect the amount of data to store between forwards.

  • store-and-forward-interval: Number of seconds between each forward attempt.

  • buffer-on-disk: Set to true to buffer intermediate data on disk in log_directory()/snf/<store-and-forward-name> instead of in memory.

  • buffer-size: Number of rows to store in buffer, when buffer is full evict the least recently pushed row - default value: 1000.
