written data volume and the status of the I/O data buffer. although the time interval for non-synchronization is very short, if the power is down or the system crashes during this period, the written data cannot be written to the disk and will be lost. Note: The kernel "writes" the data in the buffer zone to the standard input disk file. Here "write" is not to move the data in the buffer zone to the disk file, but to the disk file, in this case, a backup of the buffer content is retained in the

The 'Log file sync' wait event in the RAC database is more complex than the 'Log file sync' wait event in the Standalone Database, mainly because the RAC database needs to synchronize the SCN to all instances. The 'Log file sync' wait event in the standalone database. When the user session is committed (commit), the user session will notify the LGWR process to wr

Although asynchronous efficiency and performance are good, it cannot guarantee master-slave data consistency (if the master crash, transactions that have been committed will not be transferred to any slave.) from mysql5.5, MySQL introduces the semi-sync function to ensure d

This PR aggregates a lot of small modifications to core, Trie, ETH and other packages to collectively implement the ETH/63 Fast synchronization algorithm. In short, Geth--fast.This submission request contains minor modifications to Core,trie,eth and some other package implementations to implement the ETH/63 fast synchronization algorithm together. In simple terms, Geth--fast.# # Algorithm algorithmThe goal of the Fast Sync algorithm is to exchange pro

Often find good web sites on the Internet, the common practice is that we use favorites to save their own computer. Because the data for your favorites is stored locally, you cannot use Web site addresses that are stored in favorites on your local computer when you are on a business trip or when browsing a Web site using a browser on someone else's computer. In order to solve this problem, people will choose to use the network favorites, network favorites use more trouble. If you use Firefox to

First, IntroductionPt-table-checksum is one of the Percona-toolkit series tools that can be used to detect the consistency of the data in the master and from the database. The principle is to run on the Main library, checksum the synchronized tables and record them. It then compares the checksum of the main table to determine whether the data is consistent . The detection process in blocks, for large tables can be differentiated into multiple blocks, so as to avoid the lock table (according to a
