Distributed database solutions
In the context of the current internet era, business data is growing at a very high pace. Faced with storage and access to massive amounts of data, the traditional relational database solution of single-node storage is experiencing significant challenges. It is difficult to meet massive data in terms of its performance, availability, operation, and maintenance cost:
- Performance: Relational databases mostly use B+ tree indexes. When the amount of data is too large, the increase in the index depth will increase the amount of disk access I/O, resulting in the decline of query performance.
- Availability: As application services are stateless, they can realize low-cost local capacity expansion making the database become the bottleneck of the whole system.It has become increasingly difficult for traditional single data nodes or primary-secondary architectures to bear the pressure of the whole system. For these reasons, databases' availability...
