Snowflake (Direct Connection)

This is the recommended way to connect Snowflake to Auxia. You create a dedicated read-only role, a key-pair service user, and a warehouse in your own Snowflake account, and grant Auxia SELECT on the tables to ingest. Auxia connects directly and reads on a recurring schedule — read-only, with no tables copied or exported and no scheduled jobs for you to maintain. Before proceeding, review the Source Data Requirements to ensure your tables are ready to be connected with Auxia.

1. Overview

You provision three objects in your account — a warehouse, a service user (key-pair auth), and a read-only role — and grant the role access to the tables you want shared. Auxia authenticates as that user and reads each table directly, on a schedule, using your warehouse for compute. Flow:

Your Snowflake account                                   Auxia
      │
      │  tables / views to ingest
      │       │  GRANT SELECT to a read-only role
      │       ▼
      │   read-only role  +  key-pair service user  +  warehouse
      │       │
      │       │  Auxia connects directly (key-pair auth) and reads
      │       │  on your schedule, using your warehouse
      │       ▼
      │   ───────────────(reads in place, read-only)──────────────>  Auxia platform

Time required: ~15 minutes. Prerequisites:

A role that can CREATE WAREHOUSE, CREATE USER, CREATE ROLE, and GRANT (typically ACCOUNTADMIN).
Each shared table/view should have a timestamp column marking when a row was added/updated (e.g., UPDATE_DATE), so Auxia can read incrementally rather than rescanning the full table.

What Auxia provides: an RSA public key to register on the service user (Auxia holds the matching private key in its secret manager — no password is ever exchanged). Auxia then configures and schedules the connection on our side — the initial historical load and recurring incremental reads — and validates row counts against the source.

2. Create a Warehouse

A dedicated, auto-suspending warehouse for Auxia’s reads keeps compute cost low and isolates it for easy attribution.

CREATE WAREHOUSE IF NOT EXISTS AUXIA_INGESTION_WH
  AUTO_SUSPEND = 60                  -- suspend after 60s idle (per-second billing after a 1-min minimum)
  AUTO_RESUME = TRUE                 -- resumes automatically on the next read
  INITIALLY_SUSPENDED = TRUE;

3. Create a Key-Pair Service User

Auxia uses key-pair authentication (no password). Your Auxia solutions engineer provides the public key to paste in below.

CREATE USER IF NOT EXISTS AUXIA_INGESTION_USER
  PASSWORD = NULL
  RSA_PUBLIC_KEY = '<auxia_public_key>'   -- base64 body only — no PEM markers, no whitespace
  DEFAULT_WAREHOUSE = AUXIA_INGESTION_WH;

4. Create a Read-Only Role and Grant Access

Run the following, repeating the GRANT SELECT line for each table or view you want Auxia to read:

CREATE ROLE IF NOT EXISTS AUXIA_INGESTION_ROLE;

GRANT USAGE  ON WAREHOUSE AUXIA_INGESTION_WH                  TO ROLE AUXIA_INGESTION_ROLE;
GRANT USAGE  ON DATABASE  <your_database>                    TO ROLE AUXIA_INGESTION_ROLE;
GRANT USAGE  ON SCHEMA    <your_database>.<your_schema>      TO ROLE AUXIA_INGESTION_ROLE;

-- Repeat per object to ingest:
GRANT SELECT ON TABLE     <your_database>.<your_schema>.<table> TO ROLE AUXIA_INGESTION_ROLE;

GRANT ROLE AUXIA_INGESTION_ROLE TO USER AUXIA_INGESTION_USER;

5. Send the Details to Auxia

Share the following with your Auxia solutions engineer:

Account URL — e.g. https://<org>-<account>.snowflakecomputing.com
Username (AUXIA_INGESTION_USER), role (AUXIA_INGESTION_ROLE), and warehouse (AUXIA_INGESTION_WH)
Database / schema / table (or view) names to ingest
The timestamp/watermark column for each object (used for incremental reads)
Desired refresh cadence (e.g., hourly or daily) and when source data typically lands

Auxia configures the connection on our side, reads each object incrementally on the agreed schedule, validates row counts, and confirms before go-live.

6. Cost

Reads run on your warehouse, in your account — so warehouse compute and any Snowflake data-transfer-out are billed to you, and Auxia bears no Snowflake cost. A dedicated warehouse that auto-suspends, combined with watermark-scoped incremental reads, keeps this minimal. Auxia advises on warehouse sizing for your data volume during onboarding.
No data is copied or staged on your side — Auxia reads the tables in place; there is nothing to store or clean up.

7. Security & Governance

Read-only, scoped to exactly the tables you GRANT.
Key-pair auth, no password — Auxia holds only the private key (in its secret manager); you register only the public key.
Revocable — drop the role or disable the user to cut off all access immediately.
Rotatable — replace the user’s RSA_PUBLIC_KEY at any time; Auxia coordinates the matching private-key rotation.
Network-restrictable — you can attach a Snowflake network policy to the service user if you want to limit it to Auxia’s egress addresses (ask your solutions engineer).

8. Recommended Practices

Grant least privilege — only the databases, schemas, and tables to be ingested, on a dedicated role.
Use a dedicated, auto-suspending warehouse so Auxia’s read cost is isolated and easy to attribute; size it to your data volume (Auxia will advise).
Ensure a watermark column on each table so reads stay incremental rather than full scans.
Share base tables, not views, where possible — Auxia reads the underlying tables directly.

9. Summary

Step	Action	Owner
1	Provide the RSA public key	Auxia
2	Create the warehouse, service user, and read-only role	You
3	Grant `USAGE` + `SELECT` on the objects to ingest	You
4	Send account URL, username, role, warehouse, and the table list	You
5	Configure and schedule the connection; run the initial and incremental loads	Auxia

10. FAQ

Does Auxia create or modify anything in our environment? No. Auxia reads your existing tables in place — no copies, no exports, no schema changes, and no new pipelines. Who bears the Snowflake cost? You do, but minimally — reads run on a dedicated, auto-suspending warehouse in your account and are scoped to the watermark window. Auxia bears no Snowflake compute. Can we revoke Auxia’s access? Yes, at any time — drop the role or disable the service user. How do we rotate the credential? Replace the user’s RSA_PUBLIC_KEY; Auxia stores the private key by reference and coordinates the rotation, so it does not require reconfiguring the connection.

Prefer not to grant direct access to your account? Two alternatives are available: Secure Data Sharing (you share into Auxia’s account) and GCS Export (you push files to Auxia’s bucket). Discuss the trade-offs with your Auxia solutions engineer.
