The First-Look Analysis and Feedback Functionality (FAFF) working group, identified the need for a service that is capable of executing user-defined operations/computation following user-defined rules. This service has been referred to as Catcher. In essence, the Catcher is not that different from the Watcher or other event handling off-the-shelf technologies like Kapacitor. This technote explores the idea of using influx2.0 event processing capabilities to as an alternative implementation for the Catcher.

You can clone this repository and build the technote locally with Sphinx:
git clone https://github.com/lsst-tstn/tstn-034
cd tstn-034
pip install -r requirements.txt
make htmlNote
In a Conda environment, pip install -r requirements.txt doesn't work as expected. Instead, pip install the packages listed in requirements.txt individually.
The built technote is located at _build/html/index.html.
You can edit the index.rst file, which is a reStructuredText document. The DM reStructuredText Style Guide is a good resource for how we write reStructuredText.
