| Source | Best for | Tier required |
|---|---|---|
| CSV upload | One-off analyses, files up to 4 GB | Free + |
| PostgreSQL / MySQL / Snowflake / Azure SQL | Live data in your warehouse | Enterprise |
| Delta Sharing | Databricks UniForm shares with Iceberg metadata | Enterprise |
| Fivetran | Anything Fivetran supports — Databricks (non-UniForm), Redshift, Oracle, BigQuery, 300+ SaaS APIs | Enterprise |
How to choose
One-time analysis on a file you already have
Use CSV upload. No setup, no credentials.
Live data from a SQL warehouse
Use the database connector for Postgres, MySQL, Snowflake, or Azure SQL — direct connection, lowest latency.
Databricks with UniForm enabled
Use Delta Sharing — Iceberg-backed, type-faithful, incremental refresh.
A source not natively supported
Use Fivetran — anything Fivetran can sync, Summand can analyze.
What every source has in common
No matter the source, Summand:- Curates a Parquet copy of your data on first analysis. The source isn’t queried again until refresh.
- Generates a semantic-layer version with the same artifacts (column stats, EBM, surprises, UMAP).
- Enforces the same authorization (grants + visibility) regardless of source.
- Charges the same for analysis — pricing is per-account, not per-source.
Refresh model by source
| Source | Refresh trigger | Notes |
|---|---|---|
| CSV | Re-upload | Immediate. Replaces the file in place. |
| Database (Postgres / MySQL / Snowflake / Azure SQL) | Manual Refresh button | Full table re-read each time. |
| Delta Sharing | Manual Refresh button | Incremental — only changed partitions are re-read. |
| Fivetran | Manual Refresh button | Re-reads Fivetran’s most recent sync output; doesn’t trigger a new Fivetran sync. |
Privacy and credentials
- CSV uploads stream directly to Summand’s encrypted S3 bucket via presigned URLs. The file never passes through any application server.
- Database credentials are encrypted at rest in AWS Secrets Manager. Plaintext is never logged.
- Delta Sharing bearer tokens are stored encrypted in Secrets Manager; rotation is supported from the connector edit page.
- Fivetran holds your source credentials — Summand only sees the Parquet output. Your warehouse password never touches Summand servers.
