client from the node (fromyour embedded node ) Another way is to connect to the cluster by creating a transportclient. Important: Note that we recommend that you use the same version of clients and clusters. Because you may encounter some incompatible issues when mixing different versions. Node Client: Instantiating a node-based client is the simplest

. Requesting the client from the node (fromyour embedded node ) There is also a way to connect to the cluster by creating a transportclient. Important: Note that we recommend that you use the same version number for both the client and the cluster. Because you may encounter some incompatibility issues when mixing different version numbers. Node Client:

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 previous article introduced the client structure of elasticsearch, the client is just a façade, there is an action behind each method to undertake the corresponding Function. But action is not really a function of the implementation, it is just a proxy, its true implementation is transportaction. this article makes a simple analysis of action and Transportact

Elasticsearch provides a rich set of Java calling interfaces by constructing a client representation. In general, the client is divided into two types of cluster information in terms of client and data (index) aspects of the client. These two categories can be divided into o
