SQL Server is a relational database management system developed by Microsoft, used to store and manage large volumes of data. Azure Synapse, on the other hand, is a serverless Big Data solution developed by Microsoft that provides robust large-scale data storage and analytics capabilities.

With Erathos, you can integrate SQL Server data into Azure Synapse 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 way, your time is focused on what actually drives value — extracting valuable insights and making more data-driven decisions.

### What SQL Server data does Erathos sync to Azure Synapse?

The integration automatically syncs key SQL Server 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 SQL Server to Azure Synapse?

In Azure Synapse, you integrate SQL Server 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 SQL Server 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: 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 SQL Server connector

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

### Full control over your SQL Server 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 finding out SQL Server failed only after the business team complains. Every run is logged with runtime, processed row counts, and error context. Automatic alerts via Slack, Discord, or email as soon as anything deviates from expected behavior — keeping replication up to date without impacting the transactional database.

## Centralizing SQL Server data into Azure Synapse has never been easier

Erathos is a data ingestion platform for teams that need to replicate operational databases for analytics. With the SQL Server connector, you can incrementally sync tables and transactional records to Azure Synapse — complete with schema drift detection and full 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 SQL Server to their data warehouse — with complete observability for every run, zero maintenance, and none of the opacity of traditional market tools.

### How does Erathos replicate data from SQL Server to Azure Synapse?

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

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

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

### What happens if a SQL Server 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 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 SQL Server connector?

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