George Boole is finally vindicated in Oracle Database 23c!

Even on #Exadata, it will take a while to read 30+ TB from 3 tables. I think there is probably a way to optimize this query from an #OracleDatabase perspective. 🤨

Sometimes #OracleDatabase can seem too fast on #Exadata that you don't think there is a problem:

Really, Bard? At least tell me you're being aspirational or telling me what I want to hear. AFAIK there have never been nor can I find any reference to these #OracleDatabase parameters that could indirectly control behavior on #Exadata. 🙄

An extremely high correlation between GC CR events and poor smart scan performance on #Exadata. Even though the table was COMMITed long before the query.

Each day that goes by when I'm running queries on #OracleDatabase #Exadata, I hope that I will actually run into a case of "Delayed Block Cleanout" that I can confirm wrecks the performance of my query. 🤨

Bloom filters on #OracleDatabase #Exadata can be offloaded IF the datasets are "small enough". What is "small enough"? And what about those ~10 hidden parameters that control bloom filters? Even my biggest Exadata customers can't get a clue from Oracle Development, and it's really ticking me off. 🤬

@berx Well, I guess they want you to run everything on #Exadata. Oracle usually releases their marquee products on Exadata first?
