elasticsearch replication

Working Mechanism of ElasticSearch Like Solr, ElasticSearch is an enterprise-level search engine that is based on Apache Lucene and has high reliability. Some concepts in ElasticSearch correspond to relational databases. For example, a database is called an index in ES and a table is called a Type in ES. The specific relationship is shown in the table below. Rep

MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. The purpose of the

as quickly as possible.At first I found the solution to use the ElasticSearch River to synchronize the data, and on GitHub to the MongoDB River plugin: Elasticsearch-river-mongodb. However, then I read this blog on the ElasticSearch official online: "Deprecating Rivers", the official has been in the version after 1.5 abandoned river, for the user's migration, wi

But in many cases, our demand is: the current data stored in MySQL, Oracle and other relational traditional database, how to try not to change the original database table structure, the insert,update,delete operation results of these data in real-time synchronization to

each index setting 5 shard and a replica, indicating that the index is stored by 5 logical storage units, each logical storage unit has a replication node for disaster preparedness, note that Shard can only be set when the index is created, and the number of shard is stored on which shard the document is allocated (typically using the hash (document _ID)% Shard num Calculation document is stored on which shard)Installing the main shard and replic sli

1.ElasticSearch Simple DescriptionA.elasticsearch is a Lucene-based search server with distributed multiuser capabilities, Elasticsearch is an open source project (Apache License terms) developed in Java, based on a restful web interface that enables real-time search, Stable, reliable, fast, high performance, easy to install and use, and its scale-out capability is very strong, do not need to restart the se

?? Elasticsearch is inherently support for distributed deployments, and the availability of the system can be improved through cluster deployment. This paper focuses on the cluster node related problems of Elasticsearch, and makes clear that these are the prerequisites for elasticsearch cluster deployment and topological structure design. The configuration file o

container of data. The document is stored in a shard, and then the shards are allocated to the nodes in your cluster. When your cluster is expanding or shrinking. Elasticsearch will proactively migrate shards between your nodes to keep the cluster balanced.The Shard can be either a primary shard (primary shard) or a copy shard (Replica shard). Each document in your index belongs to a separate primary shard, so the number of primary shards determines

Solr: Advantages 1. SOLR has a larger, more mature user, development and contributor community. 2, support the addition of multiple formats of the index, such as: HTML, PDF, Microsoft Office series software format, as well as JSON, XML, CSV and other plain text format. 3, SOLR more mature and stable. 4, do not consider the index to search at the same time, faster. Disadvantages When indexing is established, search efficiency decreases and real-time index search efficiency is not high.

Distributed search Engine ElasticsearchIntroducedElasticsearch is an open source distributed search engine based on Lucene, with distributed multiuser capability. Elasticsearch is developed in Java, provides a restful interface, can achieve real-time search, high-performance computing, while the elasticsearch scale is very strong, do not need to restart the service, basically up to 0 configuration. But at t

Open source real-time log analysis Elk platform can perfectly solve our problems above, elk by Elasticsearch, Logstash and Kiabana three open source tools.

Elk System By default does not contain user authentication function, basically anyone can read and write Elasticsearch API and get data, then how to do the Elk system protection work. Target After reading this tutorial, you can learn to block unauthorized users from accessing the Elk platform to allow different users to access different index methods Here we use elastic Company's shield to complete this job shield what is Shield is a security plugin d
