I would love to see performance numbers for a GPU data warehouse on a benchmark like TPCDS. My concern is that GPUs are very fast for a few operations, but that these operations aren't the bottleneck for realistic queries, so the overall performance will not be good. I did a TPCDS-based benchmark on Redshift-vs-Snowflake-vs-BigQuery a few weeks ago [1], it could probably be run by BlazingDB without too much trouble since the data is already in GCS in Parquet format.

- arnon 9y agoTPC-DS has some incredibly complex queries that might be too complex for a database that doesn't have very extensive syntax coverage
