Embodiment

[0042] Such as figure 1 As shown, a distributed fast checklist query system, including:

[0043] The distributed cache service module adopts distributed memory computing technology and a memory-based data management engine as a storage medium for hot data, providing high-speed memory-based data storage and query services; the cache component is completely memory-based data management The engine is dedicated to solving the inherent problems of slow performance, difficult expansion, and high cost of existing databases. The cache component supports distributed cluster deployment, complete ACID consistency, and persistence. For maximum throughput, data is kept in memory (rather than on disk), which effectively eliminates buffer management. The cache component in the cluster environment distributes data to each CPU of the cluster server for processing. Each single-threaded partition executes autonomously, eliminating the need for locks and latches. It also enables a linear incr...

Abstract

The invention relates to a distributed quick list query system and method. The system comprises a distributed cache service module and a distributed disk storage service module. According to the method, hot data and cold data are separated according to the thought of data grading management, wherein a distributed cache component technology is adopted for the hot data to meet high-concurrency low-delay query requirements and improve customer experience; and the cold data is saved into a distributed disk database to provide high-capacity high-compression storage. Through the distributed quick list query system and method, distributed deployment based on x86 can be realized, and dynamic quick expansion can be realized; a service registration / subscription mechanism is supported, and service can be dynamically discovered; the cold data and the hot data are managed separately, the frequently-used hot data is stored into a host memory, and quick query service can be provided. The distributed quick list query system and method can be applied to list query supported by telecom operation and can also be applied to broader fields needing large-scale storage and a quick response to query after expansion; the design thought is ahead of peers in the industry.

Description

technical field [0001] The invention relates to a distributed fast list query system and method. Background technique [0002] For the storage of telecommunications lists, in the past, a non-distributed relational database was generally used. This storage mode is simple and convenient, can provide a combination of more complex query conditions, and supports table association queries very well, and the query response is relatively fast. However, this storage mode has problems such as low compression ratio and difficult expansion. When the data grows massively, it is often difficult to meet the requirements of rapid linear expansion. In the future, it will develop into a distributed deployment column storage database to store massive inventory data. The distributed column storage database can provide a higher compression ratio, and the expansion is relatively simple. However, the column storage database needs to decompress data during data query. , and splicing column data in...
