- 22. Druid vs BigQuery Druid Multi cloud compatible. Higher friction data load. Lower friction data maintenance. Gets more affordable with more usage. You will track who has the most data. Very fast. Slice and dice. BigQuery Fully managed and hosted, GCP-only. Low friction data load. High friction data maintenance. Price punishment for using too much. You will track who is causing cost spikes. Often slow, but faster than hadoop. Joins. Internal use cases for Druid vs BigQuery
