1.1B records = 500GB of raw CSV data. This fits into RAM quite easily on a machine like the P2.8xlarge, especially when compression is used (like MapD uses). I'd like to see how well this performs on a dataset that doesn't fit in the RAM.

Its honestly a pretty small dataset for us. MapD can easily do sub-100ms queries on 100B+ records with a single rack.

You can fit a lot of GPU + CPU memory on a small cluster. That RAM goes even further when you use compression like you mentioned.

We're fast at pulling data off of disk but we've never really aimed to be a traditional disk-based data warehouse. There are already great systems for that.

Found elsewhere on the internet: 'On a system with eight Tesla K80s, which might cost somewhere between $60,000 to $70,000, the license for the MapD stack would be “a small multiple” of this hardware cost.'

I guess I'm not playing with this anytime soon.

Is there a bridge for using MapD with Spark interface or somehow combining them? This can be interesting for the clusters with a lot of GPUs and a lot of data to do data manipulations.

That actually sounds amazing, I would totally use that. I am actually hoping that they will create GDAL bindings for geospatial data.

Still not cheap, but you could play with it on an p2.xlarge AWS instance for $4 an hour: https://aws.amazon.com/marketplace/pp/B01M0ZY2OV

Do you have any plans on offering MapD on Google Cloud Platform? (They have their own "Marketplace".)
