High-Performance MySql evolution (14th): Replication (Replication) bitsCN.com Overview The built-in replication function of Mysql is the basis for building large and high-performance applications. This distribution mechanism replicates data from a Mysql host to another server load balancer instance, and execute it again. During the

Preface The increasing demand for distributed applications requires a better distributed software environment, which constantly promotes the development of distributed technology. Oracle Data replication is a technology that implements a distributed data environment. It creates a distributed data environment by copying data on different physical sites. It is different from distributed databases. In distributed databases, although each data object is

In a federated database system, you can issue command requests to multiple data sources through a single SQL command. Before replicating between DB2 and non-DB2 databases, it is first necessary to ensure that non-DB2 data sources can be accessed by DB2 ESE Version 8 federated database. The federated d

Data Distribution is usually used in high-performance computing (HPC. There are two main data distribution topologies: Replication and partitioning. In a Data Replication environment, a data item usually has several copies, but data consistency should be ensured to a certain extent, so that the end user can only have one copy of data globally. The biggest challenge to using data

1. Preface Similar to the reason for MySQL master-slave replication, although redis reads and writes fast, it also produces a particularly high read pressure. In order to share the read pressure, redis supports master-slave replication. redis master-slave replication can be divided into full synchronization and incremental synchronization based on whether the dat

Master-slave replication configuration for redisI. Principles Redis's master-slave replication function is very powerful. One master can have multiple slave instances, and one slave can have multiple slave instances. In this way, a powerful multi-level server cluster architecture is formed. The following are some features of redis master-slave replication:1. The

If the old system is reformed, then perhaps can refer to. Translated as follows: Apache Tomcat 6.0 how to Realize cluster/session replication

First, let's look at the problems that the database often encounters:The first is the performance problem.1, upward expansion (hardware) scale up the individual itself easily reached the limit2, outward expansion scale outThe second is the question of usability.1. Database service Interruption2. damage to the wrong operation data3. Hardware Failure4. Database Upgrade test encountered bug5. Hacker attacksBased on the above problems, there is a better solution, that is, to implement the master-sla
