. As for how a shard is distributed, it is completely managed by Elasticsearch to aggregate and return search requests. These are transparent for users. In a network/cloud environment, failures may occur at any time. When a shard/node is offline or disappears for any reason, A failover mechanism is very useful and Is strongly recommended. For this purpose, Elasticsearch allows you to create one or more copi

Getting started with Elasticsearch-Installation and getting started with elasticsearch Elasticsearch is a real-time distributed search and analysis engine that allows you to explore your data at a speed and scale you have never used before. It is used as a combination of full-text search, structured search, and analysis. -- Authoritative guide

In the process of starting to access ES encountered a variety of wonderful problems.1. On-line various versions of the start-up mode is confusing to know how to start. Simple and rude--execute directly in the bin directory of ES./elasticsearch//display start, CTRL + C can stop, such as to operate, change the terminal./elasticsearch-d background boot, can continue operation at the current terminal//backgroun

available, the write replica fails for some reason, in which case the replica is considered a failure and the Shard is rebuilt on a different node.For read operations, new documents can be searched only after the refresh interval has elapsed. To ensure that the search request returns results that contain the latest version of the document, you can set replication to Sync(the default), which causes the operation to return a write request after both th

Overview replication is usually used to create a copy of the master node to ensure high availability by adding redundant nodes. Of course, replication can also be used for other purposes, such as reading and analyzing data on the slave node. In horizontally Scalable businesses, replication is easy to implement, mainly in the use of the master node for write opera

limits of a single node's hardware. For example, an index with 1 billion documents occupies 1TB of disk space, and either node does not have such large disk space, or a single node processes search requests and responds too slowly. To solve this problem, Elasticsearch provides the ability to divide the index into multiple parts, which are called shards. In a network/cloud environment, failure can occur at any time, when a shard/node is somehow offlin

MySQL replication is divided into master-slave replication and master-master replication. What is master-slave Replication refers to a master server with one or more servers as the slave servers. The slave server does not write any data. The data source is the master server. The purpose of
