Overview
CloudTable HBase supports cold and hot data separation. Data is classified and stored on different media to save costs without sacrificing functions.
The cold and hot data separation feature supports only HBase 2.4.14 and later versions.
In the cold and hot data separation scenario, hot disks do not support scale-in.
Background Information
- In a big data scenario, business data such as order data or monitoring data grows over time. As your business develops, rarely used data is archived. Enterprises may want to use cost-effective storage to store this type of data to reduce costs.
Principles
CloudTable HBase determines whether the data that is written to a table is cold data based on the timestamp of the data and the time boundary that is specified by users. The timestamp is in milliseconds. New data is stored in the hot storage and is gradually moved to the cold storage over time. You can change the time boundary for separating cold and hot data based on your business requirements. Data can be moved from the cold storage to the hot storage or vice versa.
