What is Hopsworks?

Hopsworks is a feature store that offers a state-of-the-art solution, making it one of the most feature-rich and versatile feature stores on the market. It provides the highest level of integrability with any other ecosystem, making it easy to use with a wide range of data sources. Additionally, Hopsworks offers Python APIs that are easy to use, providing developers with great flexibility. With its multitude of sources, Hopsworks allows for a seamless feature engineering workflow, making it easy for data scientists to generate training datasets from raw data. Hopsworks is ideal for businesses that require low-latency data processing and support for multiple data sources.

What is Vertex AI?

Vertex AI is the ML platform of Google, and has a feature store that enables organizations to accelerate the development of machine learning models. It provides a fully-managed machine learning platform that simplifies the process of building, training, and deploying models. Vertex AI offers a suite of pre-built algorithms and frameworks for data scientists to be able create end-to-end machine learning pipelines. Being a GCP centric platform there are obvious vendor lock-in risks in using Vertex AI.

How to choose?

While both solutions have their strengths, Hopsworks is a better choice for businesses that require low-latency data processing and support for multiple data sources. Hopsworks allows data scientists to define how features are computed and can read data from multiple sources. Additionally, Vertex AI is less versatile than Hopsworks, making it less suitable for businesses that require low-latency data processing and support for multiple data sources. Vertex also ultimately limits users to the Google ecosystem.

Join Engine

A join engine can help achieve point-in-time correctness for training data.
Big Query

Model-Specific transformations

Does the platform support transformations after the data has been stored in a Feature Table/Group .
N/A

Feature Monitoring

Is there support for identifying (and alerting) when there are anomalous changes in a feature as it is updated over time?
Feature ingestion monitoring with Great Expectations and alerting (email or slack)
Feature ingestion monitoring for feature drift and alerting

Backfill Features

Is there any additional support for specifying a job to fill up a feature table/group with feature values from data source(s) that contains historical data?
Repeated Parameterized Python or Spark Job
Batch Ingestion Job

Ranking and Retrieval Architecture Support

If you are using the feature store to build a personalized recommendation or search system, what support is there for vector DB integration?
Out-of-the-box, with OpenSearch K-NN included. External Vector Databases can be integrated.
External Vector Databases can be integrated, such Vertex Matching Engine
