Neo4j is a graph database management system designed to store and query highly connected data, representing relationships between entities efficiently. PostgreSQL, on the other hand, is a highly robust and scalable open-source relational database management system. It supports a wide range of data types and advanced features.

With Erathos, your Neo4j data lands in PostgreSQL as a reliable operational source, ready to power internal applications or reporting with standard SQL, without manual sync scripts.

### What Neo4j data does Erathos sync to PostgreSQL?

The integration automatically syncs the main Neo4j 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 syncs
- **Historical data**: full initial load followed by incremental updates

### Why sync Neo4j to PostgreSQL?

In PostgreSQL, your Neo4j data becomes available as a reliable operational source, ready to power internal applications or analytics using standard SQL.

### How it works

Erathos connects to Neo4j via the official API 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 every 5 minutes to daily), the objects to sync, and the target dataset. Every run is logged with full observability: execution time, rows processed, error context, and instant alerts via Slack or email if anything goes wrong.

## Data in your data warehouse in minutes

### Ready-to-use Neo4j connector

Replicate tables from Neo4j to PostgreSQL with incremental sync and automatic schema drift detection—without breaking pipelines when the structure changes.

### Total control over your Neo4j 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 finding out about Neo4j failures when the business team complains. Every run is logged with runtime, processed rows, and error context. Automatic alerts via Slack, Discord, or email as soon as something goes off track — keeping replication up to date without impacting the transactional database.

## Consolidating Neo4j data into PostgreSQL has never been easier.

Erathos is a data ingestion platform for teams that need to replicate operational databases for analytics. With the Neo4j connector, you can incrementally sync tables and transactional records to PostgreSQL—with schema drift detection and complete logs for every run.

## 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 Neo4j to their data warehouse—with full observability into every run, zero maintenance, and none of the opacity of traditional market tools.

### How does Erathos synchronize data from Neo4j to PostgreSQL?

Erathos uses incremental replication to sync tables from Neo4j to PostgreSQL. Schema drift is automatically detected—if a column is added or changed in Neo4j, the pipeline adapts without manual intervention.

### How often does Erathos synchronize data from Neo4j to PostgreSQL?

You can configure the sync frequency at the table level, from every 5 minutes up to daily. Erathos uses incremental synchronization—only new or updated records are processed in each run, keeping the Neo4j pipeline efficient and PostgreSQL costs predictable.

### What happens if a Neo4j 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 Neo4j connector?

Yes. Every Erathos connector includes a 14-day free trial. Connect Neo4j to PostgreSQL and start syncing immediately—no credit card required.
