Neo4j is a graph database management system designed to store and query highly connected data, efficiently representing relationships between entities. Azure Synapse, on the other hand, is a serverless Big Data solution developed by Google that provides robust storage and large-scale data analytics capabilities.

With Erathos, you can integrate data from Neo4j into Azure Synapse in just a few minutes. Our platform handles the entire data movement process to your analytical environment, allowing you to cross-reference data with other sources in your Data Warehouse. This way, your time is focused on what actually drives value — extracting valuable insights and making more data-driven decisions.

### What Neo4j data does Erathos sync with Azure Synapse?

The integration automatically syncs key 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 with Azure Synapse?

In Azure Synapse, you integrate Neo4j data into the Microsoft ecosystem: Power BI for executive dashboards, Azure Data Factory for orchestration, and distributed analytics at enterprise scale.

### 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 Azure Synapse 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: execution time, rows processed, errors with 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 Neo4j tables to Azure Synapse with incremental sync and automated schema drift detection — keeping pipelines intact when structures change.

### Full control over your Neo4j pipelines

Configure sync frequency and type per table. Data arrives in Azure Synapse integrated with the Microsoft ecosystem, Power BI, Azure Data Factory, and ML pipelines ready for use.

### 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.

## Centralizing Neo4j data in Azure Synapse 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 transactional tables and records to Azure Synapse — 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 Neo4j to their data warehouse — with full observability over every run, zero maintenance, and without the opacity of traditional market tools.

### How does Erathos sync data from Neo4j to Azure Synapse?

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

### How often does Erathos sync data from Neo4j to Azure Synapse?

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 on each run, keeping your Neo4j pipeline efficient and Azure Synapse costs predictable.

### What happens if a Neo4j 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 Neo4j connector?

Yes. Every Erathos connector comes with a 14-day free trial. Connect Neo4j to Azure Synapse and start syncing immediately — no credit card required.
