Query data out of Rerun

At its core, Rerun is a database. The OSS server is our small-scale in-memory parallel to our commercial cloud offering.

In this three-part guide, we explore a query workflow by implementing an "open jaw detector" on top of our face tracking example. This process is split into three steps:

1. Explore a recording with the dataframe view
2. Export the dataframe
3. Analyze the data and send back the results

Note: this guide uses the popular Pandas dataframe package. The same concept however applies in the same way for alternative dataframe packages such as Polars or using Datafusion directly.

If you just want to see the final result, jump to the complete script at the end of the third section.
