Compared to block storage, object storage is much newer. With object storage, data is bundled with customizable metadata tags and a unique identifier to form objects. Objects are stored in a flat address space and there is no limit to the number of objects stored, making it much easier to scale out.
The granular control that block storage offers makes it an ideal fit for applications that require high performance, such as transactional or database applications.
By itself, a block typically only houses a portion of the data. The application makes SCSI calls to find the correct address of the blocks, then organizes them to form the complete file.
What is Block Storage? Block storage is the oldest and simplest form of data storage. Block storage stores data in fixed-sized chunks called — you guessed it — ‘blocks’.

getChildContext () { return { themeColor: this.state.themeColor } }
static childContextTypes = { themeColor: PropTypes.string }
就必须写 contextTypes 来声明和验证你需要获取的状态的类型,它也是必写的
子组件要获取 context 里面的内容
