Abstract

The invention relates to a big data-oriented data stream type caching method and system. The method comprises the following steps: completing timestamp marking of each item of record information in a data stream arriving at a system to form a time sequence index; selecting the minimum time limited by a pre-configured basic data volume, and performing slicing based on the time sequence index to complete automatic fragmentation processing of a data stream time section to obtain sub-data streams of a plurality of fragments; performing determinant conversion on the data information in the sub-data stream of each fragment according to a pre-configured cacheable data column, completing real-time compression of the same data column, and forming a cache data block; and allocating idle data stream cache resources in a pre-configured data stream cache resource pool according to the size of the cache data block, and writing the cache data block into the data stream cache resources. According to the invention, a high-performance cache mechanism for data access can be provided under the condition of ensuring that the original stream sequence is not changed.

Description

technical field [0001] The invention relates to the technical field of big data processing, in particular to a big data-oriented data streaming caching method and system. Background technique [0002] The existing big data caching method is usually based on the KV form of key-value pairs, which mainly solves the need to quickly read or update the value when the key key is known. This method can only solve the demand for point-like data access and cache, and lacks a simple and effective cache solution for streaming data formed based on time series, which is more common in big data. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a big data-oriented data stream cache method and system, which can provide a high-performance cache mechanism for data access while ensuring that the original stream sequence remains unchanged. [0004] The technical solution adopted by the present invention to solve the technical problem...
