Take the answer 1：

Need to release the local lock , Otherwise, other normal transactions will be blocked . Grab the local lock first and then get the global lock , This is the read committed isolation level under distributed transactions , This forupdate Not a lock , Yes check lock . Because I got the local lock , If no other transaction owns the global lock , The distributed transaction read down has been committed ,at Other transactions of cannot get the local lock and cannot get the global lock .
