Elasticsearch get index names

There are multiple ways to list all of the indexes contained in an Elasticsearch cluster. The Elasticsearch list indexes tutorial will explain how to connect to Elasticsearch and list the indexes stored on a cluster, elasticsearch get index names. Note that the methods that will be covered in this tutorial can be used on a Windows, Mac or Linux system. A stable version of Elasticsearch, that still provides long-term support, or LTS, must be installed on the local system to have Elasticsearch list indexes.

In Elasticsearch, an index plural: indices contains a schema and can have one or more shards and replicas. An Elasticsearch index is divided into shards and each shard is an instance of a Lucene index. Indices are used to store the documents in dedicated data structures corresponding to the data type of fields. For example, text fields are stored inside an inverted index whereas numeric and geo fields are stored inside BKD trees. The following example is based on Elasticsearch version 5. All the index names and their basic information can be retrieved using the following command:. It is possible to search multiple indices with a single request.

They are not intended for use by applications. For application consumption, use the get index API. Returns high-level information about indices in a cluster, including backing indices for data streams. These metrics are retrieved directly from Lucene , which Elasticsearch uses internally to power indexing and search. As a result, all document counts include hidden nested documents. To get an accurate count of Elasticsearch documents, use the cat count or count APIs. Optional, string Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are:.

Elasticsearch , a powerful distributed search engine, plays a crucial role in modern applications for its ability to efficiently store and retrieve vast amounts of data. When working with Elasticsearch, administrators often need to monitor and manage the cluster, including obtaining essential information about its indices. Regardless of the method we choose, the response will include information about all the indexes in our Elasticsearch cluster, such as their names, document counts, storage sizes, and more. The v parameter in the URL enables a verbose output that includes column headers for better readability. The output of the code to list all the indexes in Elasticsearch will be a tabular representation of the indices, including their names and various metadata.

You use GET to retrieve a document and its source or stored fields from a particular index. Use HEAD to verify that a document exists. By default, the get API is realtime, and is not affected by the refresh rate of the index when data will become visible for search. In order to disable realtime GET, the realtime parameter can be set to false. This can be especially helpful with large documents where partial retrieval can save on network overhead.

Efficient management of Elasticsearch indices is crucial for maintaining optimal performance and ensuring the smooth functioning of your Elasticsearch environment. In this article, we will discuss some best practices and techniques for managing your Elasticsearch index list. Index templates are a powerful way to ensure consistent settings across multiple indices. They allow you to define settings, mappings, and aliases that will be applied automatically to new indices matching a specified pattern. To create an index template, use the following API call:. Index Lifecycle Management ILM is a feature that allows you to automate the management of indices based on their age and performance.
