Alpha Vantage to ClickHouse Integration
AI-first ETL from Alpha Vantage into ClickHouse. Governed entities, incremental sync, typed landing tables.
How Datrise loads Alpha Vantage into ClickHouse
Datrise syncs Alpha Vantage's time series quotes, symbols, technical indicators, fundamentals, and FX 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.
