`delete_alias`

Remove an alias. The target collection stays in place.

Example

up:
  - op: delete_alias
    alias: products_v1_legacy

# Spell out the inverse — revector does not record the previous target.
down:
  - op: create_alias
    alias: products_v1_legacy
    collection: products

Fields

Field	Type	Required	Description
`alias`	string	yes	Alias name to remove.

Reversibility

Not auto-reversible — the previous target isn't recorded anywhere, so revector can't know which collection to re-point at on downgrade. Supply an explicit down: that calls create_alias.
