This article mainly introduces what the HotDB infrastructure is like, the article is very detailed, has a certain reference value, interested friends must read it!

Indicator item:

1. No agent and similar third-party groups

Indicator requirements: do not bind software and hardware devices to implement the infrastructure, do not introduce a third-party Agent, and each function is realized by the product itself.

Deviation situation

No deviation

Note: HotDB products do not need to rely on specific versions or change the MySQL source code when using native MySQL, and there is no software dependency; deployment based on general-purpose servers or domestic servers does not require specific hardware devices, and there is no hardware dependency Various functions are implemented by themselves, such as high availability, read-write separation, etc., without the need to introduce third-party Agent (such as MHA, Zookeeper, etc.), to avoid the operation and maintenance risk of introducing third-party components and the situation in which multiple functions cannot be used at the same time. If high availability is enabled, read-write separation cannot be used.

2 、. Computing node, management platform, native * MySQL database architecture * *

Index requirements: distributed transaction database architecture is simple and clear, providing data nodes, computing nodes and management platform suite, a set of management platform can manage multiple sets of data nodes and computing nodes; loose coupling, support the original ecological database.

Deviation situation

No deviation

Description: Hot DB Server architecture consists of data nodes, computing nodes and management platform, the architecture is simple and clear; supports a set of management platform manageable platform can manage multiple sets of data nodes and computing nodes; loose coupling, supports native MySQL database, does not need to modify MySQL code and bundles with it

The details are as follows:

Technical architecture diagram

Computing node: computing node is the core of distributed transaction database HotDB Server cluster architecture, which undertakes all the work related to database services and is the lifeblood of the whole distributed service.

Management platform: distributed transaction database platform, also known as HotDB Management, can easily configure computing node database users, data nodes, table types, slicing rules and other information. At the same time, it can provide intelligent operation and maintenance services such as computing node service status monitoring, abnormal event reminder, report viewing, task management and so on.

Data node: a native My SQL database is used to store business data, and a storage node can be determined by IP, P rot and Database. In addition, there is a virtual data node concept in the HotDB Server cluster architecture, and the data node is used to represent a group of storage nodes with active / standby relationship.

HotDB can manage multiple clusters through one management platform.
