The transaction log is stored as a sequential disk file (or sometimes in a raw partition) and will generally only be written to, not read from, except in the case of rollback or recovery.
事务日志存储为连续的磁盘文件(有时存储在原始分区中)，并且一般只是用于写入而不用于读取，回滚或恢复的情况例外。
By looking at the read and write sequence counts in detail, you can further determine if the access is sequential or random.
通过仔细地观察读写序列计数，可以进一步确定访问是顺序的还是随机的。
