# FLiP-OwnTracks-MQTT

MQTT Phone App to Pulsar via MQTT

https://owntracks.org/ is a cool app you can use to send your location over HTTP or MQTT.   We will use MQTT, which is actually MoP (MQTT on Pulsar) to my Pulsar cluster.

## For a no code ingest of Location Data

So the cool thing is, all you have to do is point to the cluster via the MQTT Port and the app will send location data to a topic.   Now that it is in Apache Pulsar, I can query it with Pulsar SQL (Trino/Presto SQL).   Or I can build an Apache Spark app for ETL.   I can also write continuous SQL in Apache Flink for real-time streaming analytics on that location stream.

Easy.
