The biggest feature of sharding database is that it can be scaled horizontally. However, horizontal scaling is not a horizontal extension of the RAC, and pure sharding DB does not have an HA schema. That is, a shardcat db, multiple Shard node db. No matter who is down, it will cause no use. Let's take a look at the top down and see where there's a single point of failure and how this single point can be solved, We know that the structure of the sharding is as follows, (1). After launching from

In general, partitioning can greatly improve the performance of certain queries and maintenance operations. In addition, partitioning can greatly simplify common administrative tasks, and partitioning is a key tool for building a gigabit data system or a hyper-high-availability system.Partitioning enables you to further subdivide a table, index, or index organization table into segments, which

Not only are internet companies, including operators and financial institutions, already starting to join the trend. As the "O" in the movement of the Oracle database, naturally become the target of criticism, many CIOs and CTO have shown a desire to remove the quick expression.

Oracle RAC runs on top of the cluster, providing the highest levels of availability, scalability, and low-cost computing power for Oracle databases. If one node in the cluster fails, Oracle can continue to run on the remaining nodes. Oracle's main innovation is a technology called cache merging. Cache merging enables nodes in a cluster to efficiently synchronize

Enterprises all over the world are fighting against the high cost of their information technology infrastructure. These high costs are caused by three major factors: excessive computing power, high computing power costs, and high management costs. Grid computing is a new software architecture. It can effectively centralize a large number of low-cost modular memory and servers and create a virtual computing resource that can transparently distribute l
