be assigned on the same node.
It allows you to extend the search volume/throughput because searches can be performed in parallel on all replicas.
In summary, each index can be divided into multiple shards. Each index can also be duplicated 0 times (meaning no replicas) or multiple times. Once replicated, each index will have a primary shard (the copied original shard) and a secondary shard (a copy of the primary shard). You can define the number of fragments and replicas based on the ind
are called replication shards, or directly called replication.Reasons for the importance of replication:High availability is provided in the case of fragmentation/node failure. For this reason, it is important to note that replication shards are never placed on the same node as the original/primary (original/primary) shards.Expand your search volume/throughput because the search can run in parallel on all
centralize logging on CentOS 7 using Logstash and Kibana
Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location. It is also useful because it allows you to identify issues across multiple servers by associating their logs within a specific time frame. This series of tutorials will teach you how to install Logstash and Kibana on CentOS, and then how to add more filters to construct your log data.

You can also get some general similarities by analogy to traditional relational databases:关系数据库 ⇒ 数据库 ⇒ 表 ⇒ 行 ⇒ 列(Columns)Elasticsearch ⇒ 索引 ⇒ 类型 ⇒ 文档 ⇒ 字段(Fields)一个Elasticsearch集群可以包含多个索引(数据

6. Shards (partition) and replicas (replication): Each index theoretically can contain a large amount of data, more than the storage limit of a single node, and a single node processing such large data, will significantly limit the storage and search performance, in order to solve this problem, ES will further subdivide the index physically into multiple partitions, and these partitions are
