Question

What are the supported ways to import data into Elasticsearch?

A) Using the "import" command in the Elasticsearch console.
B) Indexing documents using the REST API.
C) Sending data via email.
D) Faxing data to a dedicated Elasticsearch fax number.

Answer 1

Importing data into Elasticsearch is typically done by indexing documents through the REST API or the Bulk API. Tools like Logstash and Beats are also used for complex data pipelines, whereas methods like the 'import' command, email, and fax are not supported.

Step-by-step explanation:

When it comes to importing data into Elasticsearch, there are several supported methods. The correct answer to your question is B) Indexing documents using the REST API. This is a common method where you can send JSON-formatted documents to Elasticsearch using HTTP POST or PUT requests. Another popular method is using Elasticsearch's Bulk API, which allows you to index multiple documents in a single request, making it efficient for importing large volumes of data.

Additionally, tools such as Logstash, Beats, and the Elasticsearch Ingest Node can be used for more complex data ingestion pipelines. These tools can transform and enrich data before it is indexed into Elasticsearch. Using the "import" command in the Elasticsearch console, sending data via email, or faxing data to a dedicated fax number are not supported methods for importing data into Elasticsearch.
