PostgreSQL is a widely used open-source relational database management system in enterprise applications. Azure Synapse, on the other hand, is an enterprise-grade analytics service that provides robust data warehousing and Big Data analytics capabilities.

With Erathos, you can integrate data from PostgreSQL into Azure Synapse in just a few minutes. Our platform handles the entire data movement process to your analytical environment, allowing you to join this 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 PostgreSQL data does Erathos sync to Azure Synapse?

The integration automatically syncs the main PostgreSQL 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** — historical backfill followed by incremental updates

### Why sync PostgreSQL to Azure Synapse?

In Azure Synapse, you integrate PostgreSQL data with 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 PostgreSQL via its 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 every 5 minutes to daily), the objects to sync, and the destination dataset. Every run is logged with full observability: runtime, rows processed, 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 PostgreSQL connector

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

### Full control over your PostgreSQL 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

Stop discovering PostgreSQL issues only after the business team starts complaining. Every run is logged with execution time, processed rows, and error context. Get automatic alerts via Slack, Discord, or email the moment something goes off track — keeping replication up to date without putting your transactional database at risk.

## Centralizing PostgreSQL data in Azure Synapse has never been easier

Erathos is a data ingestion platform built for teams that need to replicate operational databases for analytics. With the PostgreSQL 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 PostgreSQL to their data warehouse — with complete observability for every run, zero maintenance, and without the opacity of traditional tools on the market.

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

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

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

You can configure sync frequencies 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 PostgreSQL pipeline efficient and Azure Synapse costs predictable.

### What happens if a PostgreSQL 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 period for the PostgreSQL connector?

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