client加锁数量判断

因为有的时候在更新或者删除数据时，sql条件设置不合理的情况下，影响行数很多
在执行buildTableRecords时一次性加载大量数据到内存，导致内存溢出，服务宕机
为了保证服务的稳定性，希望能增加一个配置用于判断加锁数据量，当大于阈值是进行相应的异常中断，防止加载beforImage时内存溢出

Trace the client path around buildTableRecords and the beforeImage loading mentioned in the issue. Identify where a configurable lock-data threshold can be checked, then verify that exceeding it interrupts the operation with an appropriate exception before excessive memory use; the payload names no specific test or file.
