Oracle Database is a database widely used by large enterprises to store, manage, and analyze data. Clickhouse, in turn, is a robust analytical database that provides powerful large-scale data storage and analysis capabilities.

With Erathos, you can integrate data from Oracle to Clickhouse in just a few minutes. Our platform handles the entire data movement process to your analytical environment, allowing you to blend data with other sources in your Data Warehouse. This directs your time to what actually drives value — extracting powerful insights and making more data-driven decisions.

### What Oracle data does Erathos sync with Clickhouse?

The integration automatically syncs key Oracle objects:

- **Selected tables** — incremental replication of any configured table
- **Schema drift** — new columns are automatically detected and added to the destination
- **Primary keys and timestamps** — used for efficient incremental synchronization
- **Historical data** — full initial load followed by incremental updates

### Why sync Oracle with Clickhouse?

In Clickhouse, you can run OLAP queries on your Oracle data in milliseconds, making it ideal for high-concurrency dashboards and large-volume time-series data.

### How it works

Erathos connects to Oracle via official API and syncs your data incrementally — only new or updated records are processed in each run, keeping pipelines fast and Clickhouse costs predictable. You choose the sync frequency (ranging from every 5 minutes to daily), the objects to sync, and the destination dataset. Every run is logged with full observability: execution time, processed rows, errors with context, and instant alerts via Slack or email if anything goes wrong.

## Data in your data warehouse in minutes

### Out-of-the-box Oracle connector

Replicate tables from Oracle to ClickHouse with incremental sync and automatic schema drift detection — without breaking pipelines when the schema changes.

### Full control over your Oracle pipelines

Configure frequency and sync mode on a per-table basis. Data lands in ClickHouse optimized for OLAP queries, delivering millisecond-level analytics even across millions of rows.

### End-to-end observability

No more discovering Oracle issues only after the business team complains. Every execution is logged with runtime, rows processed, and error context. Automated alerts via Slack, Discord, or email as soon as something goes off script — keeping replication always up to date without putting the transactional database at risk.

## Centralizing data from Oracle to ClickHouse has never been easier

Erathos is a data ingestion platform built for teams that need to replicate operational databases for analytics. With the Oracle connector, you can incrementally sync tables and transactional records to ClickHouse—complete with schema drift detection and detailed execution logs.

## FAQ

### What is Erathos and how can it help my company?

Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect tools like Oracle to their data warehouse — with complete observability for every run, zero maintenance, and none of the opacity of traditional market tools.

### How does Erathos sync data from Oracle to ClickHouse?

Erathos uses incremental replication to sync tables from Oracle to Clickhouse. Schema drift is automatically detected — if a column is added or modified in Oracle, the pipeline adapts without manual intervention.

### How often does Erathos sync data from Oracle to ClickHouse?

You can configure the sync frequency from every 5 minutes to daily, at the table level. Erathos uses incremental syncs—only new or updated records are processed in each run, keeping your Oracle pipeline efficient and Clickhouse costs predictable.

### What happens if an Oracle sync fails?

Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full context — not just "job failed." Smart retries handle transient errors, and every run is logged with runtime, rows processed, and error context so your team can debug in minutes, not hours.

### Is there a free trial for the Oracle connector?

Yes. Every Erathos connector includes a 14-day free trial. Connect Oracle to Clickhouse and start syncing immediately — no credit card required.
