Frequently Asked Questions
What is the difference between ETL and Reverse ETL?
ETL / ELT move data into a warehouse (ETL transforms first, ELT transforms after load). Reverse ETL sends modeled warehouse data back out to SaaS apps like Salesforce so teams can act on it. Think “data warehouse as a destination” vs. “data warehouse as a source.”
How can Polytomic do both ETL and Reverse ETL when other tools can't?
Polytomic was designed from the start to do both ETL and Reverse ETL. While they are both "moving data", they require different technical architectures. WIth Polytomic, you can replace a multi-vendor stack with a single contract.
How frequent should my data syncs be?
Higher cadence means more API calls, warehouse credits, and compute, so start with the slowest interval that meets your SLA and tighten only where ROI is clear. Polytomic’s continuous mode runs as fast as every 5 minutes; for most revenue-ops or analytics cases, 15-min, 30-min, hourly, or daily schedules are cheaper and plenty fresh. We can help you determine what's best for your needs.
Why does quality of customer support matter?
When every pipeline fuels dashboards, campaigns, and revenue ops, downtime or mis-configured syncs have a direct cost. Polytomic’s proactive, engineer-led support responds in minutes to your message, not hours or days. We cut spend through proactive tuning of sync cadence and warehouse usage. We ship new connectors and features on request, quickly and reliably.
What is Fivetran?
Fivetran is a data integration platform that automatically syncs data from various sources into your data warehouse for easy analysis.
