PostgreSQL is a widely used open-source relational database management system in enterprise applications. Snowflake, on the other hand, is a serverless Big Data solution developed by Google that provides robust data warehousing and large-scale data analytics capabilities.

With Erathos, you can integrate data from PostgreSQL to Snowflake in just a few minutes. Our platform handles the entire data pipeline to your analytical environment, allowing you to join this data with other sources in your Data Warehouse. This frees up your time to focus on what actually drives value — extracting valuable insights and making data-driven decisions.

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

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** — full initial load followed by incremental updates

### Why sync PostgreSQL with Snowflake?

In Snowflake, you can combine PostgreSQL data with other sources using elastic compute, without resource contention between different teams querying the same data simultaneously.

### How it works

Erathos connects to PostgreSQL via the 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 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

### Out-of-the-box PostgreSQL connector

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

### Full control over your PostgreSQL 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 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 data from PostgreSQL to Snowflake has never been easier

Erathos is a data ingestion platform for teams that need to replicate operational databases for analytics. With the PostgreSQL connector, you can incrementally sync tables and transactional records to Snowflake—featuring schema drift detection and comprehensive 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 Snowflake?

Erathos uses incremental replication to sync tables from PostgreSQL to Snowflake. 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 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 on each run, keeping your PostgreSQL pipeline efficient and Snowflake 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 Snowflake and start syncing immediately — no credit card required.
