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, 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 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
