Compute Pool Setup

Compute Pool Setup

Create a compute pool for the migration orchestrator to run inside Snowpark Container Services.

Step 1 — Choose a Name

Ask the user:

What name would you like for the compute pool? (e.g., MIGRATION_COMPUTE_POOL)

Step 2 — Create the Compute Pool

Run the following SQL, substituting the user's chosen name:

CREATE COMPUTE POOL <COMPUTE_POOL_NAME>
  MIN_NODES = 1
  MAX_NODES = 1
  INSTANCE_FAMILY = CPU_X64_S
  AUTO_SUSPEND_SECS = 60;

Defaults: CPU_X64_S is sufficient for the orchestrator. The orchestrator itself is lightweight — it coordinates work but does not process data. MIN_NODES = 1 and MAX_NODES = 1 are recommended; the pool scales the number of nodes, not the workers.

AUTO_SUSPEND_SECS = 60 lets the pool go cold ~60s after the orchestrator service suspends, so an idle pool stops billing even if teardown is never run. It stays active while the service is running, and data_infrastructure(mode="up") resumes it before the next wave (a ~30–60s warm-up). Raise it if your migration waves run back-to-back and the warm-up is disruptive.

Step 3 — Verify the Pool Is Active

Run:

DESCRIBE COMPUTE POOL <COMPUTE_POOL_NAME>;

Check that the state column is ACTIVE or IDLE. If the state is STARTING, wait a moment and re-check — pools typically become active within a minute.

If the state is SUSPENDED, run:

ALTER COMPUTE POOL <COMPUTE_POOL_NAME> RESUME;

Then re-verify.

Step 4 — Grant USAGE to the Migration Role

The role that will run the migration needs USAGE on the compute pool:

GRANT USAGE ON COMPUTE POOL <COMPUTE_POOL_NAME> TO ROLE <MIGRATION_ROLE>;

Done

Return to ../SKILL.md; the compute pool name is passed to data_infrastructure(mode="up", compute_pool="<COMPUTE_POOL_NAME>") when bringing the shared infrastructure up (it is persisted for reuse).
