Method and device for sending data

Abstract

The invention discloses a method and device for sending data. A specific embodiment of the method comprises the steps that an operation request sent by a user terminal is received, and whether the operation request contains a key word or not is determined, wherein the key word is stored in the form of a preset fixed-length structural body; when it is determined that the operation request contains the key word, the key word is converted into a key word stored in the form of a preset non-fixed-length structural body, and then whether the operation request contains a value corresponding to the key word or not is determined; when it is determined that the operation request does not contain the value, a value which is stored in the form of a preset non-fixed-length structural body and corresponds to the key word stored in the form of the preset non-fixed-length structural body is looked up, the found value stored in the form of the preset non-fixed-length structural body is converted into a value stored in the form of a preset fixed-length structural body, and the converted value is sent to the user terminal. By means of the implementation mode, the memory utilization rate is effectively increased.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of data processing technology, and in particular to a method and device for sending data. Background technique [0002] Key-value (Key-Value) storage databases (for example, Redis storage databases), with their high performance and support for rich data structures, have occupied a large market share in NoSQL (Not Only SQL, non-relational databases) . When all the data in the key-value database is stored in memory, the program itself has made many compromises in memory space for versatility at the system design level in order to support more data structures. In the process of using many businesses, they only use simple String type storage (that is, Key-Value storage). In this application scenario, the key-value database will have too many descriptive data structures occupying memory. Cause low memory utilization, especially when the size of Key (keyword) and...

Problems solved by technology

In the process of using many businesses, they only use simple String type storage (that is, Key-Value storage). In this application scenario, the key-value database will have too many descriptive data structures occupying memory. Cause low memory utilization, especially when the size of Key (keyword) and Value (value) are relatively small, the problem of low memory utilization will become more serious, thus wasting a lot of memory resources of the server

[0003] The existing way to improve memory utilization is usually to package key-value pairs into a Hash function on the business side, but this method requires the business side to modify the business code, which is opaque to users of key-value databases
