Transform Data in Snowflake Data Cloud with Java UDFs in Tellius

It is with excitement that Tellius announces the upcoming availability of Java User Defined Function (UDF) support for Snowflake. This new integration is a result of the continued partnership between Tellius and Snowflake that was first announced in 2019.

With Java UDFs, customers can bring Java functions they built using Tellius transformations and execute them natively within Snowflake’s Data Cloud with Snowflake’s powerful processing engine, for better performance, scalability and concurrency. This greatly expands transformation capabilities and reduces management complexity from hosting external services.

Tellius provides a powerful dual engine architecture. The AI engine (ICE) enables Tellius to apply robust data transformations along with computation of insights and machine learning models. The Fast Query Engine (FQE) is used to support the search and visualization capabilities in Tellius. When organizations have an investment in Snowflake, Tellius can augment that investment by pushing Java UDF transformations built in the AI engine to Snowflake, which becomes a full-function replacement for the FQE. This is a double-impact value proposition as the total cost of operating Tellius goes down while organizations leverage the value of Snowflake compute further. See below for an architecture diagram featuring Snowflake paired with Tellius.

 

 

In the below screenshots, you can see how unstructured data in Snowflake is transformed into usable structured data by removing stop words, using a sample Java UDF executed from Tellius.

The below table in Snowflake contains Products data, with some user comments and a country code for each Product.

Using a Java UDF written in Tellius allows this data to be assigned a correct label based on a country code, as well as a cleaned Comment column to be created. This transformation is done within the Snowflake Data Cloud.

 

Data with the new columns added through Java UDF are connected to Tellius. Analysis can be done on the data, with queries initiated in Tellius pushed down to Snowflake using our Live Query capability. See the Live data that resides in Snowflake, now available in Tellius.

A variety of Java UDFs are available, including:

  1. Remove Stop Words: streamlines the tokenization of text/string-based variables.
  2. Stemming: Offers a stemming algorithm for terms
  3. Country Code Lookup: Ability to recode and standardize country codes 
  4. US State Code Lookup: Ability to recode and standardize state codes 

“With our partners at Snowflake, we are delivering cloud-native data analytics to accelerate business impact from AI and machine learning,” said Ajay Khanna, Founder and CEO of Tellius. “With the addition of Java UDF support, Snowflake customers can extend our integrated data preparation into the Snowflake Data Cloud, allowing for bespoke insights experiences without ever moving data.”

Java UDFs join other unique Tellius features for Snowflake, including writeback capabilities, Tellius Live Query for query pushdown and more. Combining Tellius with Snowflake gives users a flexible, extensible analytics platform, unlocking Snowflake’s Data Cloud for business users and analysts. Now, more users can take advantage of Snowflake enterprise data by applying a Google-like search and AI to surface insights 90% faster than traditional processes.

Java UDFs are currently in customer preview, with full public preview availability coming soon. To try Java UDFs for yourself with Tellius + Snowflake once available, sign up for a free trial at www.tellius.com/free-trial.
