Supported AWS instances
=======================

When deploying a Lakehouse node, you must choose an instance type from
the ``m6id`` family of instances. Importantly, these instances come with
NVMe drives attached to them.

**Instances are ephemeral.** These NVMe drives are used only for
spill-out space \*while processing queries, and for caching Delta Tables
on disk. All data on the NVMe drives will be lost when the cluster is
shutdown.

**System tables are persisted.** Persistent data in system tables
(users, roles, \*etc.) is stored in an attached block storage device,
and will survive a pause/resume cycle.
