Pros
  • Strong reliability handling schema changes and large-scale syncs, per reviewers
  • Broad catalog of 200+ destination integrations
  • Multi-year track record as a G2 category leader before acquisition
  • Federated SQL queries across many disparate data sources without moving or duplicating data
  • Reflections acceleration feature delivers sub-second BI query response times
  • Rated highly for ease of use and fast, direct data exploration by both technical and non-technical users
  • Strong data lake / lakehouse integration and cloud processing scores from reviewers
Cons
  • No longer sold as a standalone product — folded into Fivetran Activations after the May 2025 acquisition
  • Post-acquisition pricing moved to consumption-based Monthly Active Rows, which some reviewers found harder to predict
  • Some users report occasional out-of-memory (OOM) errors without clear diagnostic explanations
  • High resource demands and difficulty maintaining the environment at scale
  • Steep learning curve for advanced features despite a low barrier for basic querying
  • Review volume on major platforms is relatively thin for a company of Dremio's market position
