retrieve only the most recent directories.Rotation and Optimization Removing old logs becomes abnormal and simple after a time-based directory: $ curl -XDELETE 'http://localhost:9200/old-index-name/' This operation is very fast and close to deleting a small number of files of the same size.

simple restful API, making full-text search simple.However, Elasticsearch is not just lucene and full-text search, we can also describe it like this: Distributed real-time file storage with each field indexed and searchable Distributed real-time analytics search engine Can scale to hundreds of servers, processing petabytes of structured or unstructured data And, all of these features

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 IntroductionElasticsearch is a real-time, distributed search and analysis engine. It can help you deal with large-scale data at an unprecedented rate.It can be used for full-text search, structured search and analysis, and of course you can combine the three.Elasticsearch is a search engine based on the full-text search engine Apache lucene™, which can be said that Lucene is the most advanced and efficient full-featured open source searc

Introduction:For children who have just come into contact with ES, they often do not understand the meaning of the various ES concepts. In particular, the word "index" is more confused with the relational database. In this paper, through the comparison of relational database, the common es in the increment, delete, change, check the operation of graphics and text rendering. Can deepen your understanding of ES. At the same time, it also lists the graphical display under the Kibana.ES Restful

use 3 nodes dedicated to master, and these 3 nodes will not serve any client requests, and there is always only 1 active at any given time.We've figured out how to deal with the consensus in Elasticsearch and now let's see how it handles concurrency.ConcurrentElasticsearch is a distributed system that supports concurrent requests. When a Create/update/delete request arrives at the primary Shard, it is also sent to the Shard copy in parallel. However,
