Role-based Authentication
Prequel now supports role-based authentication for AWS or GCP destinations, including Redshift, Athena, S3, BigQuery, and Google Cloud Storage. This secure method allows customers to grant access directly to a given AWS IAM Role or GCP Service Account rather than sharing credentials. The platform will continue supporting credential-based authentication, and existing connections can be upgraded safely.
Frontend improvements
We’ve enhanced usability by adding the ability to sync and force refresh specific models on a per-destination basis, plus options to edit destination connection details directly in the interface.
Magic link improvements
For teams using magic links, two optional fields were added to the generation flow:
- Create as disabled: Magic link submissions can create destinations as “disabled” for manual validation before backfill starts.
- Redirect after submit: Users can be directed to a specified URI after submitting.
Advanced features
Several power-user features rolled out over the summer:
- Backfill windows: Configure maximum data batch sizes to process backfills in fixed chunks, minimizing resource bursts.
- Max concurrent transfers: A throttling mechanism limits simultaneous transfers (default: 10).
- Broader source query support: Custom query specification for reading source data, useful for partition pruning and predicate pushdown.
Bug fixes
- Duplicate form submission prevention
- Enhanced validation for error-prone fields like
host,region, andbucket_name - Improved SSH tunnel performance and connection stability
