4 Things You Can Do with Alibaba Cloud PolarDB

Product Architecture

PolarDB Features

  • High speed Single Point QBS can easily reach 500,000
    Because PolarDB uses shared distributed storage, performance when adding a new read-only node is quite high, and when sharing data, we don’t have to add a new read-only instance and replicate the data. This reduces overhead from replicating data, as adding a new read-only instance only takes 1–5 minutes. It is also completely unaffected by the size of the data in the database. What’s more, with a single master multiple read structure, we are able to keep latency down to a matter of milliseconds. We can also create backups in seconds. Each of these functions features extremely high performance.
  • Super high capacity
    Using data to a certain point, it seems that once the size reaches around 2TB most databases become useless. Today, PolarDB is capable of providing capacity of up to 100TB, which, from the perspective of relational frameworks, is an enormous amount of data.
  • Automatic scaling according to necessity
    The PolarDB data structure makes full use of the flexibility offered by the cloud, enabling the system to scale flexibly according to changes in the user’s application.
  • MySQL compatibility
    There are already more open source database instances combined than Oracle instances, and this trend is increasing every year. We are already nearing 100% compatibility, and will continue to improve support for SQL standards as quickly as possible.
  • High reliability and availability
    PolarDB uses a one master many slaves framework, which naturally offers high availability. If the master node crashes, it will automatically be directed to the command node. At the same time, the existence of multiple data copies means that the data is naturally more reliable.
