Connect a source
WHYSE reads from your warehouse. It never needs a copy of your rows to answer a question.
Supported sources
Snowflake, BigQuery, Postgres and Redshift are supported directly. Anything that speaks SQL over a JDBC-compatible connection can be added as a custom source.
whyse connect \--type snowflake \--account your-account \--warehouse compute_wh \--role whyse_reader
Read-only by default
The connection WHYSE requests is read-only. It runs the pre-aggregation query on your infrastructure and stores only the resulting cube, not the source rows.
