Understanding Bulk Indexing
Bulk indexing in Elasticsearch is done using the _bulk API. This API allows you to perform multiple index, update, delete, and create operations in a single API call. Each operation is specified in the request body using newline-delimited JSON (NDJSON).
Bulk Indexing for Efficient Data Ingestion in Elasticsearch
Elasticsearch is a highly scalable and distributed search engine, designed for handling large volumes of data. One of the key techniques for efficient data ingestion in Elasticsearch is bulk indexing.
Bulk indexing allows you to insert multiple documents into Elasticsearch in a single request, significantly improving performance compared to individual indexing requests.
In this article, we will explore the concept of bulk indexing, and its benefits, and provide detailed examples to help you implement it effectively.
