Welcome To Feldera

In this blog we will provide technical information related to the products and technologies produced by feldera.com. Feldera is an early-stage start-up that builds an incremental streaming query engine. Significant parts of the software

produced by Feldera is available using liberal open-source licenses on github.

We believe that what makes our software valuable is the fact that it brings together in a seamless way several independent technologies:

• (database) query engines
• incremental computation
• streaming computation
  

There certainly are many companies and products that offer one or more of these 3 features. However, most of the existing tools make sacrifices in one of these directions. For example, streaming databases tend to offer restricted query engines, or to support incremental computations only for restricted forms of queries.

We will start this blog with a series of articles explaining how these three seemingly disparate concepts can be unified in a very natural way, and how one can build a tool that provides all these features without compromising in any of these dimensions. In the figure below, IVM stands for Incremental View Maintenance, which is a form of incremental computation provided by databases.
