You can use RESTful API for storage and access in any place on the Internet. Its capacity and processing capability can be elastically scaled, and multiple storage modes are provided, comprehensively optimizing the storage cost.
Table Store: Provides professional data-persistent storage service and user-oriented real-time read/write operations with high concurrency and low latency.
OSS: Supports backup at an extremely low cost.
Data can be directly written to Table Store.
Data can be directly read from Table Store.
Automatic backup is supported.
Data can be re-written to Table Store through Data Integration (OSSReader and OTSWriter).
Write by whole row
Table Store Stream requires that a whole row of data be written to Table Store each time. Currently, the whole-row data write mode is applied to the writing of time sequence data such as IoT data. Therefore, data cannot be modified subsequently.
Currently, periodic scheduling is used and the scheduling interval is 5 minutes. The plugin has a latency of 5 minutes and the total latency of a synchronization task is 5 to 10 minutes.
