Embodiment Construction

[0026] The principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these specific embodiments are described only to enable those skilled in the art to better understand and implement the present disclosure, but not to limit the scope of the present disclosure in any way.

[0027] In storage systems, time series data does not have a general purpose and has its specific access patterns. For example, time-series data almost always arrives in chronological order, writes are almost always added sequentially; time-series data is rarely updated; time-series data is deleted in bulk, starting at the beginning of historical data and It is performed by connected blocks, so efficient batch deletion is important; reading recent data has very low latency and is performed almost in real time; reading is usually performed sequentially in sequence; and multiple reads ...

Abstract

The present disclosure provides a method and apparatus for storing data. The method includes: extracting metric information and metadata associated with the metric information from time series data, wherein the metric information includes a time value and a value at the time value; and storing the metric information in an object storage device, and storing the metadata Data is stored in a database. Compared with the prior art, the present disclosure provides a flexible storage design to ensure scalability of storage capacity and support fast retrieval of data at the same time.

Description

technical field [0001] The present disclosure relates generally to storage technologies, and more particularly to a method and apparatus for storing data. Background technique [0002] Recently, time-series data is becoming larger and larger in cloud systems and data centers, and technologies of virtualization and containerization have increased the number of independent nodes for typical distributed applications and services. [0003] Raw time series data is typically a sequence of data points in a format such as {UUID, measurement, timestamp, value}, which can be written directly to a data storage device such as a database or flat file. Although it has great flexibility, such a design needs to store a lot of redundant information, so it is difficult to query it in an efficient way. Furthermore, analysis tasks will suffer from severe performance issues. [0004] For example, in the specific scenario of using OpenStack as the reference cloud platform, a data point with a f...
