Load balancing algorithm in dubbo When there are multiple service providers in dubbo, there is a cluster of services. There are some algorithms for how to allocate service calls in the cluster to select appropriate services to provide services. Polling load balancing algorithm roundrobin loadbalance As the name suggests, polling is t ...

Load balancing -- consistent Hash algorithm Before talking about consistency hash, you need to hash the hash. For hash, you only need the time complexity of O(1), and then you can calculate the result. For example, in our HashMap, the hash algorithm is used to calculate the subscript of the key, but it is similar to hashing the hash value afte ...

1. Background Spring Cloud Ribbon is a client load balancing tool based on HTTP and TCP, which is implemented based on Netflix Ribbon. Through the encapsulation of Spring Cloud, we can easily automatically convert service-oriented REST template requests into client-side load balanced service calls. Although Spring Cloud Ribbon is just a to ...

prefaceEarlier, we studied the principle of RPC. There are many frameworks based on RPC, such as Dubbo. Today, we will deeply analyze Dubbo from its SPI mechanism, service registration and discovery source code and network communication process.Dubbo architecturesummaryDubbo is a high-performance and excellent open source service framework of A ...

The Cluster in Dubbo can disguise multiple service providers as one provider, specifically, disguise multiple invokers in the Directory as one Invoker. The camouflage process includes fault-tolerant processing, load balancing processing and routing processing. This article introduces Cluster related things. First, explain the concepts of fault- ...
