In the era of 64-core processors, scaling horizontally is meaningless for 99.9% of architecture designs. Latency matters to everyone, always.
Trivial queries taking nearly 1/10th of a second on modern kit is absolutely atrocious, and shows a total lack of awareness of performance as a feature.
The time reported by the REPL can be misleading.
There is work that we definitely need to do on performance as we develop PartiQL. Performance is something we have been considering since inception and we will keep considering as we go forward.
I used to do a lot of BigQuery for analytics. Latency in BigQuery is crap and clearly not it's selling point, we're not talking ms here, we're talking seconds at a minimum. Yet it's a really nice database for it's use cases.
