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

With Erathos, you can integrate data from SQL Server to Snowflake in just a few minutes. Our platform handles the entire data movement process to your analytical environment, allowing you to blend 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 SQL Server data does Erathos sync to Snowflake?

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 Snowflake?

In Snowflake, you can combine SQL Server data with other sources using elastic compute, without resource contention between different teams querying the same data at the same time.

### 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 Snowflake costs predictable. You choose the sync frequency (from every 5 minutes to daily), the objects to sync, and the destination dataset. Each 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

### Ready-to-use SQL Server connector

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

### Full control over your SQL Server pipelines

Configure sync frequency and sync type per table. Data arrives in Snowflake ready for secure sharing across teams and integration with BI and ML tools, without data duplication.

### 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 Snowflake 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 Snowflake — 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 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 sync data from SQL Server to Snowflake?

Erathos uses incremental replication to sync SQL Server tables to Snowflake. 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 Snowflake?

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 in each run, keeping your SQL Server pipeline efficient and your Snowflake 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 includes a 14-day free trial. Connect SQL Server to Snowflake and start syncing immediately — no credit card required.
