Problems solved by technology

[0002] The traditional data service method is to query from the database and then display it on the front-end page. However, some data may not be stored in the database in time when querying, and the results displayed on the page do not contain the latest data, which does not meet the needs of real-time display on the front-end. Data change needs
On the other hand, the amount of data after streaming processing is large, and the quality of the data cannot meet the direct use of the front-end. Before transmission to the front-end, further preprocessing is required to reduce the amount of data and filter out a small amount of data required by the front-end, and Streaming data is not sorted in chronological order, and the stability and accuracy of display is not as good as querying offline data

Abstract

The invention provides a data service method and device which can be used in the field of big data. The method comprises the following steps: acquiring a data demand of a target object; reading streaming data meeting the data demand from the kafka; according to the data demand, processing the streaming data; pushing the processed streaming data to a front end in a websocket mode; querying off-line data meeting the data demand from a database, and caching the off-line data to the front end; integrating the processed streaming data and the queried off-line data at the front end to obtain integrated data; and displaying the integrated data at the front end. According to the invention, data service can be provided for the front end in real time, and efficiency is high.

Description

technical field [0001] The invention relates to the field of big data, in particular to a data service method and device. Background technique [0002] The traditional data service method is to query from the database and then display it on the front-end page. However, some data may not be stored in the database in time when querying, and the results displayed on the page do not contain the latest data, which does not meet the needs of real-time display on the front-end. Data change needs. On the other hand, the amount of data after streaming processing is large, and the quality of the data cannot meet the direct use of the front-end. Before transmission to the front-end, further preprocessing is required to reduce the amount of data and filter out a small amount of data required by the front-end, and Streaming data is not sorted in chronological order, and the stability and accuracy of display is not as good as querying offline data. Therefore, there is a need for a servi...
