By adding search data through the rest API, reading the official documentation reveals that Elasticsearch supports dynamic mapping, but there are a lot of questions and listen slowly. This article mainly tells about three points content: 1 Elasticsearch Common REST API 2 Elasticsearch When adding an index, the dynamic mapping error: mapperparsingexception[failed to parse]nested; Jsonparseexception 3 Elasticsearch Adding index data using the bulk command ES REST APIThe 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

the ghost name it. Kibana is mainly used for ES analysis and querying. Elk originally completely can not take him, with ES Head and Bigdesk plug-in is also good, but Kibana management and query is indeed a lot of convenience, people, there are guns with why not use bayonets, silently think of the landlord's former owner.The Nurse-form Druid is logstash,agent just a role logstash assume, and this corresponds to indexer. The agent separately outputs the logs obtained as input to a message agent (

As stated in the previous article, ES can automatically index documents. But here's the problem-- What if the index of the default setting isn't what we want? To know es this search engine is the actual partition with index, index contains different types, different types are logical partitions, each type may contain the same field, if the type of field is the same OK, if different .... That will cause a conflict in the field. This article describes how to set the default index using t

Elasticsearch Snapshot Introductionsnapshots are typically built on a shared file system , In this case there is a snapshot of the node , Other nodes are also visible. , This can be deleted at the same time, (in the latest version of the creation of the warehouse if you do not use the shared file system will prompt you, the other nodes do not find the corresponding warehouse).
