Guides | Atlantis

The guides cover entities, database adoption, approvals, CI, membership, sandboxes, jobs, row TTL, schema history, and dropped-table recovery.

Add a new entity. Declare, plan, apply, generate — with auto-touch, soft delete, and tenant partitioning.
Adopt an existing database. Generate declarations from live tables and baseline without DDL.
Approve a schema change. Rehearse, decide, override; from exit 2 to applied.
Set up CI. Plan on pull requests, apply on merge, no repository secrets.
Manage members and callers. Roles, registration, enrolment, apply policies.
Use the sandbox. Boot, seed, checkpoint, diff, fork — in the console or from an agent.
Declare a background job. Typed jobs with handlers in your own service.
Operate jobs and workflows. Monitoring, the dead-letter queue, workflows, backfills.
Write a long-running handler. Idempotency, leases, checkpoints, resume-from-progress.
Expire rows automatically. Row TTL, and chunk-drop expiry on tenant-isolated tables.
Inspect schema history. History, diff, blame, owners, rollback.
Recover a dropped table. The 30-day parking window and how to use it.
