First, Mysql 5.6 new features....Improvements to replication features⒈ supports multi-threaded replication, (slave-parallel-workers=0 0: Disables multithreading;) it actually turns on the corresponding independent thread for each database. That is, each library has a separate (SQL thread), if the online business, only one database or most of the pressure on the individual database, multi-threaded concurrent

Mysql multi-master unidirectional -- amp; gt; ring synchronization bitsCN.com Principle:MySQL Replication is a master-slave synchronization solution for multiple MySQL databases. it features asynchronization and is widely used in various scenarios that require higher performance and reliability for MySQL. Another technique corresponding to this is the synchronize

After MySQL 5.6, the transaction header records the server UUID, which is very simple to track.Uuiduniversally unique Identifier, globally unique identifier.

group replication can run in two modes. 1. In single-master mode, group replication has the auto-select Master feature, and only one server member accepts updates at a time.2. In multi-master mode, all server members can accept updates at the same time.group replication differs from asynchronous

This article mainly introduces how Yii implements master-slave read/write splitting for multiple databases. it is a very practical technique to implement the separation of master-slave read/write for multiple databases by extending the Yii database class, for more information about how Yii implements master-slave read/write splitting for multiple databases, see t

failed hmaster task, the hbasemaster takes over and allocates hreginserver tasks. When the hreginserver fails, Zookeeper notifies the hmaster to allocate hreginserver tasks. This fully demonstratesHbaseThe forwarding function is effective.: Saliva:1,HbaseThe efficiency of failed Forwarding is relatively slow, and it is not expected to be able to switch and restore in 1-2 seconds. Maybe it is because I have not found any parameters that can speed up the process of failed forwarding and recovery,
