New Features

  • New Beta MQTT sink for publishing to an MQTT Broker: Mqtt2Service
    • Does not create a topic per data item, only four topics are used per device
    • Rational: MTConnect rates were too fast for broker and exceeded number of in-flight messages. This solves the issue.
      • Probe, Current, Sample and Assets (similar to the REST api)
        • Probe - Provides the Device definition for a given device
        • Current - Provides a snapshot of all the data items at a fixed interval (default every 10 seconds)
        • Sample - Time series deltas published on changes at a minimum interval (default every 500ms)
        • Assets - One topic per asset document organized by device
      • Review readme for configuration options.

Bug Fixes

  • Fixed Period Filter where in an edge case it would publish an additional observation not on period boundaries.

Internal Changes

  • Created an AsyncObserver for the REST and MQTT 2 Sinks. The class allows Sinks to monitor a set of data items for change and only activate asynchronously when something happens. Keeps track of sequence numbers while waiting so recipient knows where to continue from.
