Improve memory accounting and consumption in disk joins

    XMLWordPrintable

Details

    • Bug
    • Status: In Testing (View Workflow)
    • Major
    • Resolution: Unresolved

    • 2026-9, 2026-10
    • Can result in hang or crash
    • Disk joins, that may be triggered during big joins, now respect memory limits. This will prevent OOMs and, subsequently, hangups and crashes.

    Description

      Currently, the memory usage in JoinPartition. is not taken into account, and with a large number of joins, the memory consumption can increase dramatically, making disk-based joins significantly less useful than they could be.
