Oasis is a data-processing SmartNIC that offloads Parquet decoding into the network datapath as a custom hardware accelerator, and shows that Oasis hides the cost of Parquet decoding behind the network datapath with minimal overhead, overlapping the scan with the remainder of the query execution.

Valk, a performance analysis tool that combines data from multiple profilers, shows that when memory bandwidth is increased, kernels become compute bound, and makes three recommendations to fully utilize the GPUs' potential for relational workloads when the memory wall is removed.
