## A note about JupyterHub databases
The default database for JupyterHub is a sqlite database. sqlite is useful for
testing, small deployments, and workshops.
When running a long term deployment or a production system, we recommend using
a database that supports ALTER_TABLE, such as Postgres or MySQL, as it will
simplify future upgrades that may change database fields.
