, so API interfaces such as cluster and node should deny access to the upper application. At the same time, the-delete of resources that should not be deleted should also be prohibited. The ES cluster is a security guarantee, or it can easily be modified to configure the cluster or delete large amounts of data.

is: int (primary + 3 replicas)/2) + 1 = 3 However, if you only have two nodes, you cannot index or delete any documents because the number of active parts is not enough. Note: The new index has one copy part by default, which means ** requires ** two active parts to meet the quorum requirements. Of course, this default setting will prevent us from performing operations in a single node cluster. To avoid this problem, the specified quantity takes effe

cluster that, as part of a cluster, stores your data and participates in the indexing and searching capabilities of the cluster. A node can be joined to a specified cluster by configuring the cluster name. By default, each node is scheduled to be added to a cluster called "Elasticsearch", which means that if you start several nodes in your network and assume that they can discover each other, they will automatically form and join a "

Elasticsearch is a distributed, restful search and Analysis server, like Apache SOLR, which is also based on the Lucence Index Server, but I think the advantages of elasticsearch contrast SOLR are: Lightweight: Easy to install startup, download files after a command can be started; Schema Free: A JSON object of arbitrary structure can be submitted to the server, and the index structure is specifie

the above structure still does not solve such things as: sorting, aggregation, facet, because we may want to read a lot of unnecessary information.So, another data structure solves this problem: Document Values. This structure is essentially a column-like storage, which optimizes the storage structure with the same type of data.To improve efficiency, elasticsearch can read all of the document value under the index into memory, which greatly increases
