Elasticsearch supports two types of protocols:HTTP protocol.Native Elasticsearch Binary Protocol (local Elasticsearch binary protocol): Elasticsearch protocol for inter-node communication developed independently.You can also extend the supported protocols by using plug-ins. There are some official plugins.A second appr

Brief Analysis of the client source code of Elasticsearch, elasticsearchclientProblem It makes us learn with problems more efficient. 1. Can the client automatically discover all nodes in the cluster when only one node is configured in the es cluster? How was it discovered? 2. How does the es client achieve load balanc

The deletion of Elasticsearch is also very flexible, next time I introduce, DeleteByQuery the way. Today, we will introduce a deletion based on the ID.
