Essentia Query

Great, you have a lot of data, but how do you know what to do with it? Being able to explore your data without having to load everything into a database beforehand is a very necessary and useful step in deciding which data should be analyzed and how to analyze it.

With Essentia you can take a subset of your data and run SQL queries on it without loading anything into a database table. By streaming the data from S3 or a local directory directly into the query, you can quickly explore a subset of the files you plan to process before you commit a large amount of your resources to analyzing the full set of data.


First, the Essentia scanner allows you to easily categorize your data so you pick exactly the files you want to explore. Then you can query those files with simple SQL statements that allow you to quickly get an idea of what your files contain and how they might be analyzed.

Essentia also makes it easy to explore the contents of your files by streaming them into a variety of Essentia commands and any UNIX command. Start making use of this versatility to explore your own data and download Essentia for free today.
