Query and Transform

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 for alternative dataframe packages such as Polars or using Datafusion directly.
