More research is needed on what systems typically support. This would make ADBC more useful in situations where it supplies data to other systems, since then those systems could query statistics using a standard interface and integrate them into query planning. (Interestingly, Spark at least doesn't seem to have this in DataSourceV2 - I suppose the smarts are directly in their JDBC support.) Examples: - Estimated result set size for queries (basically, a semi-standardized EXPLAIN (ANALYZE)) - Parquet-style min/max/null % statistics per column -- This is an automated message from the Apache Git Service.
