ElasticSearch-Basic Concepts
For articles translated by others, it is very important to master the following basic concepts for learning Elasticsearch. You can try to align the following concepts with MySQL (databases, tables, data rows, fields.
Basic Concepts
Elasticsearch has several core concepts. Understanding these concepts from the very beginning will be of
Full-text search engine Elasticsearch getting started tutorial,
Full-text search is the most common requirement. Open-source Elasticsearch (hereinafter referred to as Elastic) is the first choice for full-text search engines.
It can quickly store, search, and analyze massive data volumes. Wikipedia, Stack Overflow, and Github all use it.
The underlying layer of Elastic is the Open Source library Lucene.
We have started elasticsearch in the previous article, and then we can communicate with elasticsearch, such as inserting data, retrieving data, deleting data, and so on. Elasticsearch provides two ways to communicate with Java APIs and restful APIs. Java API
If you are using the Java,elasticsearch built-in two client,
1. Install Elasticsearch cluster1. Download elasticsearch-2.0.0.tar.gz, perform TAR-ZXVF elasticsearch-2.0.0.tar.gz decompression2. Modify CONFIG/ELASTICSEARCH.YML (be careful not to shelf the first letter with a space, followed by a space after the colon)If you want to configure the cluster to require two nodes on the Elasti
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 API
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 ~

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,
