ES Writer
An Elasticsearch writer component is designed to write the data stored in an Elasticsearch index. Elasticsearch writers typically authenticate with Elasticsearch using username and password credentials, which grant access to the Elasticsearch cluster and its indexes.
All component configurations are classified broadly into the following sections:

In Elasticsearch, an index is a collection of documents that share similar characteristics, and each document within an index has a unique identifier known as the index ID. The index ID is a unique string that is automatically generated by Elasticsearch and is used to identify and retrieve a specific document from the index.

Resource types are defined at the time of index creation, and they provide a way to logically separate different types of documents that may be stored within the same index.
