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. You can put it in crontab in the middle of the night. Optimizing indices is a good thing to do during off-peak hours. Because it can increase your search speed. W

limits of a single node's hardware. For example, an index with 1 billion documents occupies 1TB of disk space, and either node does not have such large disk space, or a single node processes search requests and responds too slowly. To solve this problem, Elasticsearch provides the ability to divide the index into multiple parts, which are called shards. In a network/cloud environment, failure can occur at any time, when a shard/node is somehow offlin

indexed in Elasticsearch.Elasticsearch opens up a REST API and you'll find many document examples are HTTP calls that you can try using tools such as curl or postman.Of course, the client for this API has been written in many different languages, including. Net, Java, Python, Ruby, and JavaScript.Logstash is an open source data collection engine with real-time processing power. Data can be collected dynamically from different sources, and processed (

Rest interface Now that we have a functioning node (and cluster), the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful rest API that allows you to interact with your cluster using this REST API. Here are a few things you can do with this API: 1, check your cluster, node and index health status and various statistical information2. Manage your clusters, nodes, index data, and

You can use your favorite Web client, and you can even communicate with Elasticsearch via the Curl command. basic usage of Restful APIs:The part of the reque

refer to the multi of ES documents. Update ES also support updates, but the update is done through a provided script. The ES approach is to find the appropriate node for the record by index, then execute the script, and then return to the new index after execution. In fact, a get and reindex process is performed, in which the versioning controls no other update operations (this feature is available after 0.19). The principle of concrete implementation should be related to

This blog provides an easy way for Elasticsearch to index multiple documents. The support of Bulk API can implement batch add, delete, update and so on once request. The bulk operation uses the UDP protocol, and UDP cannot ensure that data is not lost when communicating with the Elasticsearch server.First, Bulk APIWith the bulk command, the REST API _bulk ends with a bulk operation written in the JSON file,
