CREATE BRANCH

Create a new branch that is based on the current one that you are in.

Syntax 
CREATE BRANCH [ IF NOT EXISTS ] <branch_name>
   [ { FROM | AT } { REF[ERENCE] | BRANCH | TAG | COMMIT } <reference_name> ]
   [ IN <catalog_name> ]

Parameters​

[ IF NOT EXISTS ] Optional

When included, the command will run regardless of whether the branch exists and you will receive a summary indicating whether the branch could be created. If this clause is not specified, the command will fail if the branch to be created already exists.

<branch_name> String

The name of the branch that you are creating. If an Arctic catalog is not specified, the branch is created in the catalog specified in the query context.

{ FROM | AT } { REF[ERENCE] | BRANCH | TAG | COMMIT } <reference_name> String   Optional

Specifies the reference from which or at which you want the new branch to be created. When this parameter is omitted, the current reference is used.

  • REF: Identifies a specific branch, tag, or commit.
  • BRANCH: Identifies a specific branch.
  • TAG: Identifies a specific tag.
  • COMMIT: Identifies a specific commit. Commit hashes must be enclosed in double quotes (for example, “ff2fe50fef5a030c4fc8e61b252bdc33c72e2b6f929d813833d998b8368302e2”).

IN <catalog_name> String   Optional
