(strength) based on confidence Apriori uses an iterative approach called layered search , which is used to search for "K-set" K-1. First, the entire transaction is scanned to find a set of frequent 1-itemsets, which is recorded as L1. L1 is used to find collection L2 for frequent "2 Itemsets", while L2 is used to find L3. So go on until you can't find the K set. Looking for every LK needs a database scan. The core idea is: Connecting steps and pruning steps. The connection step is a k-2, the pr

Recently tried a little etcd to do the registration discovery of the service "Etcd Service" Download the binary file from Etcd's official website and allocate three machines to do the cluster 10.0.1.98 etcd-001 10.0.1.205 etcd-002 10.0.1.182 etcd-003 Then start the service with a script Etcd--name etcd-002--initial-advertise-peer-urls http://10.0.1.205:2380--listen-peer-urls http://10.0.1.205:2380- -listen-client-urls http://10.0.1.205:2379,http://1

automatic discovery system. Classification of system parameters In a system environment that uses an ANT script for deployment, there are several types of system parameters that are commonly used: Basic parameters of the operating system such as host name, domain name, system user name and password, etc. Application Server Parameters such as Web server installation path, profile path, Java Server installation path, application instance name, We

Objective The previous section explains the knowledge points and simple examples of service registration and discovery in stand-alone mode. In the actual production or in a distributed environment of this microservices architecture, it is necessary to consider the high availability of each component in the event of a failure. In fact, high availability, my simple vulgar understanding is that through the redundancy of the system is highly availab

ETCD is a highly available key-value storage system that is used primarily for shared configuration and service discovery. ETCD is developed and maintained by CoreOS and is inspired by ZooKeeper and Doozer, which is written in the go language and handles log replication through the raft consistency algorithm to ensure strong consistency. Raft is a new consistency algorithm from Stanford, suitable for the log replication of distributed systems, raft to

Everything starts from here. The prism document is a bit harsh on the two concepts, or even self-defeating. I 'd better not read them. We know that in each module, the module class that implements the imodule interface must implement the initialize method of this interface. On the one hand, we must register some custom interfaces and classes that implement this interface, prepare for the subsequent dependency injection. On the other hand, load the view for Region and display it (initialize the v

Recently in the thinking of a problem, the online server run a variety of services, it may be running Nginx, another run is MySQL, the other is to run NFS or other services, etc. Through a certain script fixed write some services to implement monitoring all the server's process resource consumption Zabbix server resources do not say, if the server ran the service is not on the fixed list, the monitoring service can not get the corresponding data.In order to solve this problem, recently in the Za

Service discovery is one of the key principles of micro-service architecture. Trying to configure each client or some form of convention can be very difficult and very fragile. Consul provides service discovery services through HTTP APIs and DNS. Spring Cloud Consul uses the HTTP API for service registration and discovery. This does not prevent non-spring cloud a

This service is now used to be very small, and it is recommended that you use it manually, so that we can use it when we need to use it, If your computer discovers that this service corresponds to the Svchost.exe process using the CPU very much, can turn it off, but it is not recommended to permanently disable it to start, let's learn more about SSDP Discovery service. 1 The process that corresponds to the SSDP
