> @yanxinyi View's not getting deleted while parent was dropped has something to do with SYSTEM.TASK? Do we save some intermittent state while dropping view in SYSTEM.TASK? Yes we use the SYSTEM.TASK table for dropping child views asynchronously whenever a drop <parent table/view> cascade command is issued. By setting these configs, we are ensuring that the background TaskRegionObserver thread does not automatically pick up DropChildViewTasks. This prevents race conditions in the test and makes it more deterministic since we already explicitly call runDropChildViewsTask() in the test case wherever cascade drops are issued: https://github.com/apache/phoenix/blob/ba6ad70541d9dae88ab574df3889f5fe2c0ef7fa/phoenix-core/src/it/java/org/apache/phoenix/end2end/ViewMetadataIT.java#L720-L726 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
