Using Parseable with Datasette for OpenTelemetry traces — [Parseable](https://www.parseable.com) is a brand new observability tool, compatible with [OpenTelemetry](https://opentelemetry.io), for storing and querying observability data.
I saw Parseable in a Show HN today - it's a new observability platform with both an open source (AGPL) Rust implementation (a single ~180MB binary), an "Enterprise" version with extra features and a cloud hosted option.
Since Datasette 1.0a41 added OpenTelemetry support (thanks, Alex Garcia), I decided to fire up Codex and have it figure out how to run Parseable and feed it traces from Datasette.
Here's my (human-written) TIL showing the patterns that worked, and here's a screenshot of a Datasette trace displayed within the Parseable localhost web application:
