Description of RonDB#

RonDB is designed to be used in a managed cloud environment where the user only needs to specify the type of the virtual machine used by the various node types. RonDB has the features required to build a fully automated managed RonDB solution.

It is designed for appplications requiring the combination of low latency, high availability, high throughput and scalable storage (LATS).

You can use RonDB in a Serverless version on app.hopsworks.ai. In this case Hopsworks manages the RonDB cluster and you can use it for your machine learning applications. You can use this version for free with certain quotas on the number of Feature Groups (tables) you are allowed to add and quotas on the memory usage. You can get started in a minute with this, no need to setup any database cluster and worry about its configuration, it is all taken care of.

You can use the managed version of RonDB available on hopsworks.ai. This sets up a RonDB cluster in your own AWS, Azure or GCP account using the Hopsworks managed software. This sets up a RonDB cluster provided a few details on the HW resources to use. These details can either be added through a web-based UI or using Terraform. The RonDB cluster is integrated with Hopsworks and can be used for both RonDB applications as well as for Hopsworks applications.

You can use the open source version and use the binary tarball and set it up yourself.

You can use the open source version and build and set it up yourself.

This is the commands you can use to retrieve the binary tarball:

# Download x86_64 on Linux
wget https://repo.hops.works/master/rondb-26.02.0-linux-glibc2.28-x86_64.tar.gz
# Download ARM64 on Linux
wget https://repo.hops.works/master/rondb-26.02.0-linux-glibc2.28-arm64_v8.tar.gz

These versions are also available as Docker containers at hub.docker.com under hopsworks/rondb. See https://hub.docker.com/r/hopsworks/rondb/tags for an up to date of which RonDB container images are available. These containers can be used to run RonDB in containers, in Hopsworks they are also used since version 4.0 as containers in the Hopsworks Kubernetes cluster.

The actions to build both x86_64 and ARM64 tarballs have now been fully automated.
