Introduction If you use elasticsearch to store your logs, this article provides you with some practices and suggestions. If you want to collect logs from multiple hosts to elasticsearch, you have the following options: Graylog2 is installed on a central machine. Then it inserts logs into elasticsearch, and you can use its beautiful search interface ~ Logstash

It requires that all processes/nodes in the system must agree on the value/state of the given data. There are already many consensus algorithms such as raft, Paxos, and so on, mathematically proved to be OK. However,

Elasticsearch is an advanced, high-performance, extensible open-source search engine that provides both structured and unstructured data for full-text search and real-time analysis. It features a RESTful API that can be easily integrated into existing Web architectures using HTTP. Therefore, in the case of high concurrency, we can use Nginx reverse proxy load balancer to multiple Elasticsearch servers. Arch

Elasticsearch is a distributed document storage engine. It can store and retrieve complex data structures in real-time-serialized JSON documents. In other terms, once the document is stored in Elasticsearch, it can be retrieved on any node of the cluster.Of course, we not only need to store data, but also to quickly bulk query. While there are already many NoSQL solutions that allow us to store objects as d

Today, we introduce an open source distributed search engine Elasticsearch.First, Elasticsearch is a Lucene-based search server. It provides a distributed multi-user-capable full-text search engine, based on a restful web interface. Elasticsearch is the second most popular enterprise search engine developed in Java and published as an open source under the Apache license terms. Designed for cloud computing,

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
