ILM is a feature that helps to manage time series data and automates the creation, management and deletion of an Elasticsearch index. It can also automate the creation when an index reaches the optimal size and age/time.
One idea is that In this article, we will briefly discuss how Elasticsearch works internally and explain the basic query APIs. All the data in Elasticsearch is internally stored in Apache Lucene as an inverted index. Although data is stored in Apache Lucene, Elasticsearch is what makes it distributed and provides the easy-to-use APIs.
A frequent query we ran across in our research was “How does Elasticsearch indexing work?”.
During the indexing process, Elasticsearch stores documents and builds an inverted index to make the document data searchable in near real-time. Indexing is initiated with the index API, through which you can add or update a JSON document in a specific index.
We can find out. elasticsearch stores the data in the form of document. The documents are JSON objects that are stored in Elasticsearch index. In other words, the document is considered as a base unit of storage that can be indexed.
What is the use of monitor in Elasticsearch?

Yes, the free and open features of Elasticsearch are free to use under either SSPL or the Elastic License. Additional free features are available under the Elastic License, and paid subscriptions provide access to support as well as advanced features such as alerting and machine learning.
How are monitoring indices retained in Elasticsearch Service?

What is Ilm in SQL Server?
ILM: Manage the index lifecycle edit You can configure index lifecycle management (ILM) policies to automatically manage indices according to your performance, resiliency, and retention requirements. For example, you could use ILM to: Spin up a new index when an index reaches a certain size or number of documents.
