Problems solved by technology

Every time a sequence is obtained, it is necessary to access the Zookeeper distributed system and create a new persistent sequence node, which is relatively inefficient and does not meet the requirements of the distributed database for rapid response to the sequence.

Abstract

The invention discloses a global sequence generating method and device based on zookeeper. The method comprises the following steps: distributing a plurality of sequence generators, initializing sequences generated by the sequence generators to assign step lengths, loading factors and initial values for the sequences and setting a memory queue; acquiring distributed locks of zookeeper sequence nodes in a zookeeper distributing system; calculating step length sequence values of the zookeeper sequence nodes according to the current values and the step lengths of the zookeeper sequence nodes; releasing the distributed lock of the zookeeper sequence nodes to obtain step length sequence values which correspond to the zookeeper sequence nodes; asynchronously filling the step length sequence values into the memory queue of the sequence generator; and selecting a sequence value form the memory queue as a global sequence, and returning the global sequence. According to the technical scheme, a unique global sequence can be provided, and business requirements are met.

Description

technical field [0001] The invention relates to a database middleware, in particular to a zookeeper-based global sequence generation method and device. Background technique [0002] zookeeper is a distributed, open source distributed application coordination service, an open source implementation of Google's Chubby, and an important component of Hadoop and Hbase. It is a software that provides consistent services for distributed applications. Its functions include: configuration maintenance, domain name service, distributed synchronization, group service, etc. [0003] At present, due to the huge transaction volume of the telecom business system, the distributed database is used as the underlying data storage, so the auto-increment sequence of the database can no longer provide a globally unique sequence. Most of the current distributed auto-increment sequences generate ordered sequences based on Zookeeper's own strong consistency and the sequential characteristics of persi...
