## Proposed changes #36235 introduced, index page is not freed in query thread, so saved tracker ptr when alloc page, so that page only needs to be freed before query ends. ``` F20240624 18:44:51.880192 162249 mem_tracker_limiter.cpp:125] mem tracker label: Query#Id=f0511107829e465e-a87a985234018b77, consumption: 94, peak consumption: 636540, mem tracker not equal to 0 when mem tracker destruct, this usually means that memory tracking is inaccurate and SCOPED_ATTACH_TASK and SCOPED_SWITCH_THREAD_MEM_TRACKER_LIMITER are not used correctly. 1. For query and load, memory leaks may have occurred, it is expected that the query mem tracker will be bound to the thread context using SCOPED_ATTACH_TASK and SCOPED_SWITCH_THREAD_MEM_TRACKER_LIMITER before all memory alloc and free. 2. If a memory alloc is recorded by this tracker, it is expected that be recorded in this tracker when memory is freed. 3.
