    Fix Databricks: databricks query slow with many joins

    This usually indicates avoidable scan, join, or compute overhead in the current SQL shape.

    Why this happens

    Complex join graphs, broad SELECTs, and low-selectivity predicates can drive high cost in Databricks.

    How to fix it

    1. Reduce scanned data early with targeted filters and explicit columns.
    2. Review join predicates and remove unnecessary DISTINCT/UNION operations.
    3. Run an automated lint pass to catch anti-patterns quickly.
