@gianm Fixed the join issue: node scans shared the caller's `ResponseContext`, so the right side's scanned-row counts made the outer limited Scan return no rows. Each system-table leaf now gets its own response context. Tests: - `NativeSysServerPropertiesQueryTest#testInSubqueryOnSameSystemTable`: your query (`IN` subquery on `sys.server_properties`, `LIMIT 5`), with both planners. - `SystemTableQueryClientTest#testNodeScansDoNotShareCallerResponseContext`: node scans don't update the caller's response context. -- This is an automated message from the Apache Git Service.
