But in many cases, our demand is: the current data stored in MySQL, Oracle and other relational traditional database, how to try not to change the original database table structure, the insert,update,delete operation results of these data in real-time synchronization to

GitHub upgraded their code search in January 2013 and changed it from SOLR to elasticsearch, the current cluster size is 26 index storage nodes and 8 client nodes (responsible for processing search requests).

The loggly Log Management Service uses Elasticsearch as a search engine in many of its core functions. In his article "ElasticSearch vs SOLR", Jon Gifford noted that the field of log management has a higher demand for search technology. In general, it must be able to: Reliable large-scale real-time indexing-for us, processing more than 100,000 log data per second; High-performance, reliable pro

Preface: Elasticsearch is committed to hiding the complexities of distributed systems, and the following operations are done automatically at the bottom:Partition your documents into different containers or shards (shards), they can exist in one or more nodesDistributes shards evenly across nodes to load-balance search for indexesRedundancy of each shard to prevent data loss due to hardware failureRoute requests on any node in the cluster to the node
