wlessard_ca··on Fast drilldown dashboards from a single Parquet file
How is this any different from the old OLAP cubes like IRL / Express? The cube is basically an array in memory and super fast, the dashboards based on Group By as well. I was an Express consultant at Oracle, great to see old concepts come back to life if it’s what I think it is.
