> Before committing to such spec change, it would be great to have good understanding on how much real-world improvement it would bring, Based on my observations, in addition to standard queries for counting or determining minimum/maximum values in ad-hoc analysis, count/min/max queries are frequently used on dashboards. These queries are either run dynamically or help users create their own queries. Additionally, Agg pushdown can handle a broader range of queries by supporting predicates and groupings by partition columns. > cause it's not like the current file-level metadata is useless for aggregation queries speedup. It's just that eg in Trino it's not utilized to the maximum yet. @findepi do you mean min/max and count from the Iceberg metadata are already used for query planning? though none of them used for the agg pushdown? -- This is an automated message from the Apache Git Service.
