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 zookeeper-based global sequence generation method and device. The method includes: allocating multiple sequence generators, and initializing the sequences generated by the sequence generators to specify step size, loading factor, and initial value for each sequence And set a memory queue; obtain the distributed lock of the zookeeper sequence node in the zookeeper distributed system; calculate the step size sequence value of the zookeeper sequence node according to the current value and the step size of the zookeeper sequence node; release the distributed lock of the zookeeper sequence node, Obtain the step sequence value corresponding to the zookeeper sequence node; asynchronously fill the step sequence value into the memory queue of the sequence generator; and select a sequence value from the memory queue as the global sequence, and return the global sequence. The technical solution of the invention can provide a unique global sequence to meet business requirements.

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...
