Exchange Rates API to ClickHouse Integration
AI-first ETL from Exchange Rates API into ClickHouse. Governed entities, incremental sync, typed landing tables.
How Datrise loads Exchange Rates API into ClickHouse
Datrise syncs Exchange Rates API's exchange rates, currency pairs, base currencies, rate dates, and historical rates into ClickHouse as a MergeTree table per source entity. Flexible or custom fields land in JSON or Map columns, and timestamps such as created, updated, and status changes are typed as DateTime64.
Sync is incremental: Datrise uses inserts into a ReplacingMergeTree keyed on stable id, so the latest version wins on merge, so re-runs update only what changed. Partition by month and order by (entity id, updated-at) for fast range scans. ClickHouse deduplicates asynchronously on merge, so Datrise uses ReplacingMergeTree and FINAL-safe queries rather than assuming immediate upserts.
Ideal for high-volume event analytics that need sub-second aggregation.
Endpoints
