Rename a function

Creating and updating a function requires:

An admin or server key. See Keys and Permissions for details.
The privilege to create/update a function, granted in an Attribute-based access control (ABAC) role.

Problem

You need to change the name of a function within the current database.

Solution

Use the Update function:

Update(
  Function('create_post'),
  {
    body: Query(
      Lambda(
        ['title', 'body', 'author'],
        Create(
          Collection('posts'),
          {
            data: {
              title: Var('title'),
              body: Var('body'),
              author: Var('author'),
            },
          }
        )
      )
    ),
  }
)

{
  ref: Function("create_post"),
  ts: 1624310581310000,
  name: 'create_post',
  body: Query(Lambda(["title", "body", "author"], Create(Collection("posts"), {data: {title: Var("title"), body: Var("body"), author: Var("author")}})))
}

Query metrics:

bytesIn: 268
bytesOut: 362
computeOps: 1
readOps: 0
writeOps: 1
readBytes: 187
writeBytes: 346
queryTime: 18ms
retries: 0

Discussion

After a function has been renamed, any queries that attempt to call the function by its old name fail.
