`delete_payload_index`

Drop an index from a payload field. The field stays in the payload — only the index goes away.

Example

up:
  - op: delete_payload_index
    collection: products
    field_name: category
    schema: keyword          # optional, but needed for auto-rollback

Pass schema: when you want the downgrade to be auto-reversible — revector uses it to reconstruct the matching create_payload_index.

Fields

Field	Type	Required	Description
`collection`	string	yes	Collection that holds the index.
`field_name`	string	yes	Payload field whose index to drop.
`schema`	`PayloadSchemaType`	no	Original field schema. Required for auto-reversibility.

Reversibility

Auto-reversible iff schema: is supplied → recreates the index via create_payload_index.
Without schema:, revector has no way to know the original field type and refuses the auto-downgrade; supply an explicit down:.
