[GitHub] [doris] xinyiZzz opened a new pull request, #12794: [fix](memtracker) Introduce orphan mem tracker to verify memory tracking accuracy
xinyiZzz opened a new pull request, #12794:
URL: https://github.com/apache/doris/pull/12794
# Proposed changes
Issue Number: close #xxx
## Problem summary
The mem hook consumes the orphan tracker by default. If the thread does not attach other trackers, by default all consumption will be passed to the process tracker through the orphan tracker.
In real time, consumption of all other trackers + orphan tracker consumption = process tracker consumption.
Ideally, all threads are expected to attach to the specified tracker, so that "all memory has its own ownership", and the consumption of the orphan mem tracker is close to 0, but greater than 0.
