Abstract

Provided are a method and system for managing memory data, a method and system for maintaining data in a memory, and a computer-readable storage medium and a computing device corresponding to the provided methods and systems. The method for managing memory data comprises: setting a data table comprising multiple shards, each shard corresponding to a first-level skip list; setting the first-level skip list to be configured to store a node where a first attribute value of data is used as a keyword and a pointer or an object for indicating a second-level skip list is used as a value corresponding to the keyword; and setting the second-level skip list to be configured to store a node where a second attribute value of the data is used as a keyword and a value corresponding to the keyword comprises at least one attribute value of the data. According to the present disclosure, the time consumed for reading / writing data can be reduced, and the number of data write tasks and / or data query tasks executed simultaneously in the unit time can be increased.

Description

technical field [0001] The present invention generally relates to the field of memory data management and maintenance, and more specifically, to a method and system for managing memory data, a method and system for maintaining data in memory, and corresponding computer-readable media and computing devices . Background technique [0002] Existing databases include relational databases and non-relational databases. Relational databases such as MySQL and SQL Server are mainly used to manage and maintain relational data. Non-relational databases such as Redis and MongoDB are mainly used to manage and maintain non-relational data. Relational data refers to data based on a relational model (Relational Model, RM for short). Non-relational data means data that is not based on a relational model. [0003] In order to process time series data, a time series database (TimeSeries Database, TSDB for short) such as InfluxDB is proposed. In order to manage data in memory, an in-memory...
