database.update()

Learn: Databases and multi-tenancy

Update a child database's metadata and settings.

Signature

update(data: { *: Any }) => DatabaseDef

Description

Updates a child database's metadata and settings, represented as a Database document, with fields from a provided data object.

Fauna stores child databases as documents in the parent database’s Database system collection. Database documents have the DatabaseDef type.

During the update, fields from the data object are copied to the document, creating new fields or updating existing fields. The operation is similar to a merge.

Nested fields

Fields with nested objects in the data object are merged with the identically named nested object in the document.

Remove a field

To remove a document field, set its value in the data object to null.

You can’t use this method to insert or edit the following metadata fields:

  • coll

  • ts
