All training data synced from W&B is stored in a local DuckDB database at ~/.telescope/. You can change this location with the TELESCOPE_DATA_DIR environment variable.

Compression

Over time the database can grow large. The Database option in the sidebar menu shows the current database size and lets you compress it. Compression can reduce size by 20–30% depending on the data, by re-exporting and re-importing the database with optimized storage. During compression, syncs are paused automatically and resume when it finishes.
