flowmap.query

Database

flowmap.query currently only supports ClickHouse as its database backend. ClickHouse is a scalable column-oriented database. It's shows great query performance especially for aggregation queries over large single-table datasets. This makes ClickHouse a great choice for supporting interactive analysis of OD-datasets with attributes.

We plan to add support for BigQuery and Google Sheets in the future.
