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
One of my most fulfilling tasks as a developer is optimization: making certain parts of my product kiln run faster. Because even if your product has the best features, or the most appealing interface, it's still worthless if it's slow and unbearable. Last year, my team got an opportunity to optimize the slowest part of the kiln and eventually improve it much faster than before.
This article describes how a good tool called Elasticsearch can help us t
ElasticSearch cluster creation instance
I started to research and search, and set up a simple ElasticSearch search cluster on my own virtual machine. I hope it will be helpful.

Installation, running, and basic configuration of Elasticsearch
Elasticsearch is a superb real-time distributed search and analysis engine. It can help you process large-scale data at an unprecedented speed. It can be used for full-text search, structured search, and analysis. More importantly, it is easy to get started and the api is clear. According to the official introduction, currently Wikipedia, Githu

Premise
With the rapid development of artificial intelligence and big data, fast retrieval of terabytes and even petabytes of big data has become a requirement, and large enterprises have already drowned in the vast stream of data generated by the system. Big Data technologies are already focused on how to store and process these massive amounts of data. Elasticsearch as a rising star in the field of open source, from 2010 to date has been a leap-
