real-world applications, partitioned tables will not have as many partitions as 3 in the test case, but dozens of or even hundreds of. This locking result will exacerbate the lock conflict in the update situation, causing the transaction to be in a lock-wait state. As shown, each transaction has an n row lock, so the possibility of these locking records covering each other is greatly improved, resulting in a decrease in concurrency and reduced effici
