Description

Syntax proposal: https://docs.google.com/document/d/1jEF4IkWu-2Gzk5ii2Nb0exuEnAUeo98UbiM3i0xtgWQ/edit?usp=sharing

This PR supports @ syntax in INSERT, DELETE, UPDATE, MERGE statements:

    | INSERT INTO qualifiedName ('@' branch=identifier)?
       columnAliases? rootQuery                                        #insertInto
    | DELETE FROM qualifiedName ('@' branch=identifier)?
         (WHERE booleanExpression)?                                    #delete
    | UPDATE qualifiedName ('@' branch=identifier)?
        SET updateAssignment (',' updateAssignment)*
        (WHERE where=booleanExpression)?                               #update
    | MERGE INTO
        qualifiedName ('@' branch=identifier)? (AS? alias=identifier)?
        USING relation ON expression mergeCase+                        #merge

Also, add new syntax to manage branches:

    | CREATE (OR REPLACE)? BRANCH (IF NOT EXISTS)? identifier
        (WITH properties)? IN TABLE qualifiedName                      #createBranch
    | DROP BRANCH (IF EXISTS)? identifier
        IN TABLE qualifiedName                                         #dropBranch
    | ALTER BRANCH source=identifier IN TABLE qualifiedName
        FAST FORWARD TO target=identifier                              #fastForwardBranch
    | SHOW BRANCHES IN TABLE qualifiedName                             #showBranchs

Relates to #12844

awesome PR!
iceberg branching will be so usefull.
Any plan to be embed this in an upcomming release or is it too early ?

ALTER BRANCH source=identifier IN TABLE qualifiedName
        FAST FORWARD TO target=identifier                              #fastForwardBranch

When we want the changes from the branch experiment in main does this correspond to

ALTER BRANCH main IN TABLE test-table
        FAST FORWARD TO experiment
