# Proposed changes
Issue Number: close #xxx
## Problem summary
The mem hook record tracker cannot guarantee that the final consumption is
0, nor can it guarantee that the memory alloc and free are recorded in a
one-to-one correspondence.
In the life cycle of a memtable from insert to flush, the memory free of
hook is more than that of alloc, resulting in tracker consumption less than 0.
In order to avoid the cumulative error of the upper load channel tracker,
the memtable tracker consumption is reset to zero on destructor.
