Label:Elasticsearch has a plug-in module called River that can import data from an external data source into a elasticsearch and index it. The river is a singleton pattern on the cluster, it is automatically assigned to a node, and when the node is hung, the river is automatically assigned to another node. Currently supported data sources include: Wikipedia, MongoDB, CouchDB, RabbitMQ, RSS, Sofa, JDBC, File
First, IntroductionElasticsearch is a Lucene-based search server. It provides a distributed multi-user-capable full-text search engine, based on a restful web interface. Elasticsearch is a popular enterprise-class search engine developed in Java and published as an open source under the Apache license terms. Designed for cloud computing, it can achieve real-time search, stable, reliable, fast, easy to install and use.Second,
First, the cluster roleNodes in a multi-machine cluster can be divided into master nodes and data nodes, using the Zen Discovery (Zen discovery) mechanism in the configuration file to manage different nodes. Zen Discovery is the default discovery mechanism that comes with ES, using multicast to discover other nodes. As soon as you start a new ES node and set the same name as the
, and then stores the index on the Shard.Replicas is a backup,Elasticsearch uses the Push replication mode , when you index a document above the Master Master Shard, The Shard copies the document To all the remaining replica replica shards, these shards will also index this document. I personally think this model is very nice, sometimes the index of a document may produce a large index file, will be very much bandwidth, and only transfer the original

Elasticsearch provides a very comprehensive and powerful rest API that you can use to interact with your cluster. The few things you can do with the API are as follows:
Check your cluster, node, and index health status and statistics
Managing cluster, node, and index data and metadata

Elasticsearch is a very popular full-text search engine, but online tutorials are mostly used for the first time, and there are no advanced usage demos. This encounter need to cross-network segment network problems, their own exploration of the document for a long time, found to be feasible, so began to do an experiment, the final experiment success. Automatic discovery and networking are implemented under cross-network segments.A total of three nodes
