weavori estimate

Pre-scan a database schema and report expected generation characteristics.

Last updated October 20, 2018

Usage

$weavori estimate [dsn] [flags]

The estimate command connects to a PostgreSQL database, introspects its schema, and reports the table count, approximate row counts (from PostgreSQL's built-in statistics), and an estimated generation time — without generating or writing any data. Use it to verify connectivity and size a generation run before starting it.
