6 Best Elasticsearch ETL Tools in 2022
ElasticSearch is a distributed, open-source, real-time search and analysis system that enables you to go beyond simple full-text search and perform complex operations to access, collect, index, and filter data.
Using Elasticsearch as a data source organizations can extract data for analysis on other BI platforms. And, when using Elasticsearch as back-end storage, organizations require a way to inject data from multiple sources into their Elasticsearch data storage.
In this article, we will list out the 6 best Elasticsearch ETL Tools available to analyze your Elasticsearch data. Read along to learn more about them and decide which of these Elasticsearch ETL tools suit you the best.

What is Elasticsearch?
Elasticsearch is an open-source tool that acts as a distributed engine for search and analytics for all kinds of structured and unstructured data. Elasticsearch can be used to index documents. It is fast, scalable, and it can handle huge quantities of data.
When you load a document to Elasticsearch, it creates a reverse index of all the fields in that document. This data is stored in JSON form and can be queried.
Elasticsearch is frequently used as a part of the ELK (Elasticsearch, Logstash, and Kibana) stack. Logstash provides loading and transformation capabilities. Kibana is used to visualize Elasticsearch data. Elasticsearch has APIs to add documents to the index (Index API), retrieve documents (Get API), query over the index data (Search API), and add additional fields to an index (Get API). Elasticsearch works using a cluster of servers, which can be scaled by adding more servers.
Some important use-cases of Elasticsearch are as follows:
- Application search
- Website search
- Enterprise search
- Logging and log analytics
- Infrastructure metrics and container monitoring
- Application performance monitoring
- Geospatial data analysis and visualization
- Security analytics
- Business analytics

What is ETL?
ETL — Extract, Transform, and Load — simply stands for the transfer and the transformation of data using data pipelines. In general, data is extracted from multiple sources, transformed, and loaded into a data lake or a data warehouse for analytics.
If you are using Elasticsearch then you might need to perform ETL to move the data to a business analytics platform or a Data Warehouse. To achieve this you can select any one of the numerous Elasticsearch ETL Tools available in the market.

Limitations of Manual ETL
- Manual ETL is labor-intensive and takes a very long time to get right.
- Manual ETL also requires heavy technical expertise.
- Data security can be an issue if not managed correctly.
But manual ETL for your Elasticsearch data can be completely avoided using some good Elasticsearch ETL Tools.

2) Logstash
Another important choice among the Elasticsearch ETL Tools is Logstash. It is an Elastic company’s product built to collect, store, and manage data from logs. It is an open-source tool and it can collect data from multiple sources in real-time. But Logstash is not just about data collection from logs. It can transform data using its output plugins, filters, and native codecs.
Logstash processing pipeline has three stages. Input, filters, and outputs, which generate, modify, and ship them respectively. Logstash although is extremely effective, however unlike other Elasticsearch ETL Tools, it requires a level of technical expertise to handle.
3) Apache NiFi
Apache NiFi is an open-source tool used to automate data transfer between software. NiFi has a web-based UI and provides a configuration facility, great design, control, low latency, and dynamic prioritization. NiFi can work on work on several nodes improving processing performance. You can write SQL queries locally in NiFi that process Elasticsearch data. Like Logstash, NiFi is also suitable for programmers with high levels of technical expertise.
4) Apache Spark
Apache Spark is an open-source, large-scale data processing engine. It is one of those Elasticsearch ETL Tools that provides high performance for batch and streaming data. Using Spark, you can transform data, and process it in real-time. Spark supports multiple programming languages and different types of structured or semi-structured data.
5) StreamSets
StreaSets Data Collector is an open-source software using which you can build enhanced data ingestion pipelines for Elasticsearch. These pipelines can adapt automatically to changes in schema, infrastructure, and semantics. It can clean streaming data and handle errors while data is in motion. There can be multiple unwanted changes in data streams called data drifts, which affect the quality of data and StreamSets lets you build reliable pipelines to combat that.
6) CloverDX
You can work with Elasticsearch as a source or as a destination and transform the data using the CData JDBC Driver for Elasticsearch. The JDBC Driver lets you use CloverDX’s transformation components. CloverDX is a Java-based tool for automation of data integration, offering a highly scalable and available, distributed environment.
