Goal

Providing an application programming interface (API) to collect result tuples of the Squall pipeline. A graphical user interface (GUI) or automatically updated terminal interface like (h)top has can be easily developed by means of this API. However, developing these interfaces isn't the main object, they are just by-products of having a well designed API.

• Result tuples will be collected in a specified node
  • Since results may come from multiple nodes, some buffering mechanisms are needed somewhere in the system.
• Up to date results
  • Although buffering is applied, online execution will be preserved.
• Configurable rate
  • Update interval of results is easy to adjust.
• Error bounds will be provided
  • Currently, error bounds aren't calculated by Squall, if it is implemented API will be able to handle to give some certainty for results.
