Oracle Database is a database widely used by large enterprises to store, manage, and analyze data. Amazon Redshift, on the other hand, is a cloud data warehouse designed for fast and efficient analysis of large data volumes.

With Erathos, Oracle data lands in PostgreSQL as a reliable operational source, ready to power internal applications or reporting with standard SQL, without manual sync scripts.

### What Oracle data does Erathos sync to Redshift?

The integration automatically syncs key Oracle objects:

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

### Why sync Oracle to PostgreSQL?

In PostgreSQL, your Oracle data becomes available as a reliable operational source, ready to power internal applications or analytics using standard SQL.

### How it works

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

## Data in your data warehouse in minutes

### Oracle connector ready to use

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

### Total control over your Oracle pipelines

Configure sync frequency and type by table. Erathos uses intelligent UPSERT in PostgreSQL—ensuring data consistency even during reprocessing.

### 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 PostgreSQL has never been easier.

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

## FAQ

### Why migrate from Oracle to Postgres?

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 full observability into every pipeline run, zero maintenance, and none of the black-box opacity of traditional market tools.

### How does Erathos synchronize data from Oracle to PostgreSQL?

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

### How often does Erathos synchronize data from Oracle to PostgreSQL?

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

### What happens if an Oracle synchronization 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 execution is logged with run time, processed rows, and error context so your team can debug in minutes, not hours.

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

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