DROP BRANCH

Remove a branch from an Arctic Catalog.

Syntax 
DROP BRANCH [ IF EXISTS ] <branch_name>
  { AT COMMIT <commit_hash> | FORCE }
  [ IN <catalog_name> ]

Parameters​

[ IF EXISTS ] Optional

When included, the command will succeed regardless of whether the branch existed. If this clause is not specified, the command will fail if the branch to be dropped does not exist.

<branch_name> String

The name of the branch that you are dropping.

AT COMMIT <commit_hash> | FORCE String

Use the AT COMMIT parameter when you want to specify the exact commit hash that the branch is expected to be at. This is helpful to prevent the branch from being dropped if it was modified unexpectedly. Commit hashes must be enclosed in double quotes (for example, “ff2fe50fef5a030c4fc8e61b252bdc33c72e2b6f929d813833d998b8368302e2”). Use the FORCE parameter when you want to drop the branch even if it has been changed.

IN <catalog_name> String   Optional

The name of the Arctic catalog containing the branch that you want to drop. If not specified, the current Arctic catalog in the query context is used.

Examples​

Drop a branch at the specified commit 
DROP BRANCH myBranch
  AT COMMIT "ff2fe50fef5a030c4fc8e61b252bdc33c72e2b6f929d813833d998b8368302e2"
