Actian Avalanche is a hybrid cloud/on-premises, columnar (with compression) data warehouse offering provided as a managed service when in the cloud.
Avalanche is a relatively new offering, having only been released in March 2019. As such it lacks some features that we would like to see, notably geospatial and time-series capabilities, which will be important for some IoT applications. That said, this sort of functionality are on the roadmap and expected to be released in the second half of 2020. Leaving that aside, the product shows significant promise.
