Fantastic
Super easy to deploy and use with data lake formats in S3, everything works out of the box. Super good stuff.
Very good user experience
Following the instructions, I was able to deploy a working environment in ~10 minutes and run queries against the supplied sample S3-based dataset. The CFN-based marketplace experience is flawless. The Dremio UI is intuitive and the query performance is very impressive. If you're looking for a solution that supports running BI applications against data residing in S3 (or other data stores for cross-cloud compatibility) Dremio is definitely worth a look. I appreciate the value. I only ran into one glitch (and this may have been my error) - After you deploy the environment, make sure that you record the public or private URL that points to primary Dremio Web UI for the deployed EC2 instance in your region. Coming back to the environment a few days later following a client reboot, I couldn't figure out how to retrieve the primary endpoints for the Web UI even after exploring the marketplace and AWS console interfaces. (I suspect I missed something)
