1 What is SolrcloudSolrcloud (Solr Cloud) is a distributed search solution provided by SOLR, when you need large-scale, fault-tolerant, distributed indexing and retrieval capabilities when using Solrcloud. When the index data of a system is less than the need to use Solrcloud, when the index is very large, the search request concurrency is very high, then need to use Solrcloud to meet these requirements.　　Solrcloud is a distributed search scheme based on SOLR and

On an introduction to "Building Dubbo distributed Platform-dubbo", combined with Dubbo Basic introduction, today we will learn the installation based on zookeeper registry.Registration Center1. We recommend using the Zookeeper Registration Center client with dubbo-2.3.3 or above version2, Zookeeper is Apache Hadoop sub-project, the strength is relatively good, it

I first recognized zookeeper and made some records. Zookeeper provides a centralized service, including configuration maintenance, service naming, distributed synchronization, and group management. Sub-services are commonly used in distributed applications. Zookeeper Architecture Zookeeper is an open-source Distribute

Observer: Make zookeeper more scalable one, zookeeper Observer1.1 zookeeper roleAfter the introduction, I think we all know that in the zookeeper cluster there are two roles leader and follower. Leader can accept client requests and receive write requests forwarded by other servers, and is responsible for updating the

In a distributed environment, most services allow partial failures and data inconsistency. However, some of the most basic services require high reliability and consistency, these services are the basis for other distributed services, such as naming service and distributed lock. These distributed basic services have the following requirements: High Availability High Consistency High Performance Designing a service that challenges the CAP principle is a challenge and a good research topic. A

Zookeeper is a Distributed , open-source Distributed Applications Coordination Services, is Google the chubby a Open Source implementation, is an important component of Hadoop and HBase.

Zookeeper is one of the many excellent software that the Hadoop ecosystem provides for the open source session. The previous time project used zookeeper, mainly used as a service for registration and discovery using a way similar to Ali's Dubbo. In fact, the Zookeeper feature is more than just this content, it provides a series of very powerful features that will

Zookeeper is not designed for high availability Many systems need to be deployed across data centers for Disaster Tolerance. For cost-effectiveness, we usually allow multiple data centers to work at the same time, instead of setting up n times of redundancy. That is to say, a single data center cannot support full traffic (Can you imagine that Google has only one data center working in the world ). Because the
