Backups and local development

Local snapshot backup

marketdata backup-data freezes local caches, universes, and configuration files into a snapshot directory with manifest.yml. It does not overwrite an existing snapshot.

marketdata backup-data --preset a_share_current --name a_share_current_20260526

Standard layer and DuckDB queries

marketdata data catalog --artifacts-root "$DATA_PLATFORM_ROOT"
marketdata data materialize --help
marketdata data query --artifacts-root "$DATA_PLATFORM_ROOT" --sql "select 1 as value"

Install DuckDB support with:

uv sync --extra dev --extra duckdb
