Arguments

None

Options

Option Description

--[no-]color

Enables or disables color formatting for the output. Color formatting is enabled by default if the terminal supports it (determined using chalk/supports-color). Use --no-color to disable.

--dir

A local directory of .fsl files. Defaults to the directory specified in .fauna-project.

--endpoint

Fauna server endpoint.

--environment

Environment to use from .fauna-project.

--help

Help for the command.

--secret

Authentication secret. Overrides the secret in .fauna-shell.

Use a scoped key to interact with a child database using a parent database’s admin key.

For example, with a parent database’s admin key secret of fn123, you can access a child database by appending the child database name and role: fn123:childDB:admin.

--timeout

Connection timeout in milliseconds.

--url

Database URL. Overrides the url in .fauna-shell.

Examples

Basic example

To check the status of staged schema:

fauna schema status

The response includes a status for the staged schema and a summary of any staged or local changes:

Connected to endpoint: cloud-us
Staged status: ready
Staged changes:

  * Modifying collection `Customer` at collections.fsl:4:1

(use `fauna schema commit` to commit staged changes)
Local changes:

  * Modifying collection `Customer` at collections.fsl:4:1

(use `fauna schema diff` to display local changes)
(use `fauna schema push` to stage local changes)

Run a staged schema change

You typically use the schema status command as part of a staged schema change.

A staged schema change lets you change one or more collection schema without index downtime due to index builds.

To run a staged schema change, you must use the Fauna CLI. You can’t run a staged schema change using FQL schema methods or the Fauna Dashboard.

To run a staged schema change using the CLI:

  1. Make the desired changes to .fsl files in your schema directory.

    You can’t use a staged schema change to delete or rename schema. Instead, delete or rename the schema in a separate unstaged schema change.

  2. Use fauna schema push to stage the schema changes. fauna schema push stages schema changes by default:

    fauna schema push

    A database can have one staged schema change at a time. You can update staged schema using fauna schema push.

    When a database has staged schema, any access or updates done using FQL’s schema commands on related system collections interact with the staged schema, not the database’s active schema.

    For example, when schema changes are staged, Collection.all() returns Collection documents for the staged collection schema, not the database’s Collection documents.

    If a database has staged schema, you can’t edit the database’s active schema using FQL, the Dashboard, or an unstaged schema change. You must first abandon the staged schema change.

  3. Use fauna schema status to check the status of the staged schema:

    fauna schema status

    Possible statuses:

    Staged status Description

    pending

    Changes are being processed. New indexes are still being built.

    ready

    All indexes have been built. Changes are ready to commit.

    failed

    There was an error during the staging process.

  4. When the status is ready, use fauna schema commit to apply the staged schema to the database:

    fauna schema commit

    You can only commit staged schema with a status of ready.

    If you no longer wish to apply the staged schema or if the status is failed, use fauna schema abandon to unstage the schema:

    fauna schema abandon
