ClickHouse to PlanetScale Integration
AI-first ETL from ClickHouse into PlanetScale. Governed entities, incremental sync, typed landing tables.
How Datrise loads ClickHouse into PlanetScale
Datrise syncs ClickHouse's tables, rows, partitions, materialized views, table schemas, and merge parts into PlanetScale as a typed table per source entity. Flexible or custom fields land in JSON columns, and timestamps such as created, updated, and status changes are typed as DATETIME.
Sync is incremental: Datrise uses a watermark on updated-at, applied with INSERT … ON DUPLICATE KEY UPDATE, so re-runs update only what changed. Vitess sharding by tenant or entity key for very large tables. PlanetScale disallows foreign-key constraints by default, so Datrise models relationships by stable id columns rather than enforced FKs.
Ideal for horizontally scalable MySQL apps on Vitess.

FAQ
How does Datrise handle ClickHouse's custom fields in PlanetScale?
Flexible values are stored as JSON columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native PlanetScale types.
