Sienge is the leading technology ecosystem in the construction and real estate industry in Brazil. Used by more than 9,000 clients — including 77 of the country's top 100 construction companies —, Sienge centralizes project management, finance, purchasing, contracts, inventory, and post-sales in a single integrated platform. Amazon S3 is AWS's object storage service, the foundation for modern data lakes supporting formats like Parquet and Iceberg.

With Erathos, you can integrate data from Sienge into Amazon S3 in just a few minutes. Our platform exports data in Parquet format, ready for consumption by Athena, Glue, Spark, or any analytical engine in the AWS ecosystem. This allows your team to build the construction data lake they've always wanted — without brittle pipelines and manual maintenance.

### What Sienge data does Erathos sync to Amazon S3?

The integration automatically syncs the main objects from Sienge:

- **Projects** — daily logs, schedules, cost estimates, and physical progress
- **Finance** — accounts receivable, invoices, ledger entries, and cash flow
- **Contracts** — customer data, units, status, and revision history
- **Purchasing** — orders, suppliers, quotes, and purchase orders
- **Inventory** — material movements, balances, and requisitions
- **Units** — real estate properties, developments, delivery status, and post-sales

### Why sync Sienge to Amazon S3?

S3 is the foundation of the modern data lake on AWS. By centralizing Sienge data in S3 using Parquet, you make it accessible to Athena, Redshift Spectrum, EMR, and SageMaker — building advanced analytics for project costs, delay forecasting, and profitability per development without relying on Sienge's native reports.

### How it works

Erathos connects to Sienge via official APIs and exports data in Parquet format directly to your S3 bucket. Syncing is incremental — only new or updated records are processed in each run, organized by date partitions to allow efficient staging and queries. Every single run is tracked with complete observability: runtime, processed rows, errors with context, and instant alerts via Slack or email.

## 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 their tools — like Sienge — to their data lake, without the maintenance cost of in-house pipelines or the opacity of traditional ETL tools. Our customers reduce pipeline maintenance by up to 80%.

### Does Erathos sync Sienge historical data to Amazon S3?

Yes. During the first sync, Erathos performs a full historical load of the Sienge data, exported in Parquet format to S3. From then on, subsequent syncs are incremental — only new or modified records are processed and added to the corresponding partitions.

### How often does Erathos sync Sienge data to Amazon S3?

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 exported in each run, keeping your Sienge pipeline efficient and your S3 costs predictable.

### What happens if a Sienge sync fails?

Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full context — not just 'job failed.' Intelligent retries handle transient errors, and every run is logged so your team can debug in minutes, not hours.

### Is there a free trial available for the Sienge connector?

Yes. Every Erathos connector includes a 14-day free trial. Connect Sienge to Amazon S3 and start syncing immediately — no credit card required.
