With the growth of users, business and data, related problems such as backup, performance, migration, upgrade, read-only instance, disk capacity, Binlog delay caused by I/O bottlenecks (storage and network) gradually appear; too many database storage engines The engineering efficiency and operation and maintenance costs have increased significantly due to the type of product, and it is best to have a general product technology architecture that can take into account the needs of different user scenarios. In response to the above-mentioned problems of relational databases in the cloud hosting environment, Alibaba Cloud will launch PolarDB, a self-developed general-purpose cloud database, in late September, which is the first key milestone product in China that can fundamentally solve two major pain points.
Alibaba Cloud PolarDB is the first self-developed general-purpose cloud database in China. It has the same performance as commercial databases, but the price is only 1/10 of the former. The need for continuity, online business expansion, and data security will completely subvert the era of huge profits for commercial databases.
In the product architecture, the support of multi-channel concurrent writing of general distributed database OLTP is abandoned, and the architecture design of one write and multiple reads is adopted, which simplifies the theoretical model that is difficult to take into account in distributed systems, and can meet the application scenarios and performance of most OLTP. Require. In addition to greatly improving OLTP performance and storage capacity, it also further reduces the cost of using commercial-grade databases on the cloud.
So here comes the question:
1. In practical applications, what problems do you still encounter on the database to be solved?
2. In database applications, which indicator or function do you value most?
3. In order to achieve cost-effective, fast read-only expansion and breakthrough of single-machine capacity, what do you think the ApsaraDB for PolarDB needs to do?
