Easily move your data from Elasticsearch to Databricks to enhance your analytics capabilities. With Hevo’s intuitive pipeline setup, data flows in real-time. Check out our 1-minute demo below to see the seamless integration in action!

Elasticsearch is one of the top players when it comes to logging or log-based analytics use cases. Although Elasticsearch is known for its efficiency, knowledge of Elasticsearch Domain Specific Language (DSL) is a must. And, if you are struggling with DSL, you might want to replicate your data to Databricks instead.

Databricks supports standard SQL, and its functionalities are on par with Elasticsearch. Databricks can easily handle complex queries.

You can replicate data with the help of CSV files using Python to replicate your data from Elasticsearch to Databricks, or use an automated data pipeline like Hevo to ease the replication process.

Why You Should Integrate Elasticsearch with Databricks?

Elasticsearch to Databricks integration has the following benefits:

  • Streamline Data Processing & Reporting: Leverage Elasticsearch for fast search and Databricks for scalable transformations and reporting.
  • Combine Search with ML Workflows: Use Elasticsearch for querying and Databricks for building machine learning models on the retrieved data.
  • Advanced Analytics on Indexed Data: Analyze Elasticsearch data in Databricks using Spark SQL, visualizations, and complex aggregations.
  • Unify Real-Time & Historical Data: Use Elasticsearch for live data access and Databricks for storing and analyzing historical trends.

Methods to Replicate Data from ElasticSearch to Databricks

You can replicate data from Elasticsearch to Databricks using either of the two methods:

Method 1: Replicating Data from ElasticSearch to Databricks using CSV Files

Export Data from Elasticsearch to CSV: Use Python and Pandas to query Elasticsearch and export the data to a CSV file.

from elasticsearch import Elasticsearch
import pandas as pd

es = Elasticsearch()
response = es.search(index='your_index', body={}, size=100)
docs = pd.json_normalize([hit['_source'] for hit in response['hits']['hits']])
docs.to_csv('output.csv', index=False)

Upload CSV to Databricks: In Databricks, go to the “Data” tab, drag and drop the CSV file, or browse your file system to upload it. Once uploaded, create a table from the CSV.

Modify and Query Data in Databricks: After uploading, modify data types as needed and preview the table by selecting the appropriate cluster.

Challenges Faced While Replicating Data

In the following scenario, using CSV files might not be a wise choice:

  • You will need to perform the entire process frequently to access updated data at your destination to achieve two-way sync.
  • The CSV method might not be a good fit for you if you need to replicate data regularly, since it’s time-consuming to replicate data using CSV files. 

Companies can use automated pipelines such as Hevo to avoid such challenges. Hevo helps you replicate data from databases such as PostgreSQL, MongoDB, MariaDB, SQL Server, etc.

Using an automated data pipeline tool, you can transfer data from Elasticsearch to Databricks.
