Description
Is your feature request related to a problem? Please describe.
no, this is an enhancement
Describe the solution you'd like
We would need to have metrics about Data Skew, something like :
Task.Who 240228 00QA000000fxamQ (Lead)
Task.Who 240227 00QA000000fxbXA (Lead)
Case.Account 111268 001A000000v5ReG (Account)
Case.Account 99528 0011H00001ktMUD
Case.Account 91124 001A000000v6nnW
Describe alternatives you've considered
At Salesforce, internal tools can help but the customers need to have this information on their own
Additional context
1. Record Lock Contention
When a parent record has 10K+ children, any DML operation (insert, update, delete) on a child record requires a lock on the parent record
2. Sharing Recalculation Performance
If the parent record's ownership or sharing changes, Salesforce must recalculate sharing for all 10K+ child records
This causes system delays org-wide
3. Account Data Skew (Most Common)
The most frequent form — one Account with tens of thousands of Contacts, Opportunities, Cases etc.
Severely impacts page load times for the parent Account record
Related lists become slow.
4. Query & Report Performance
Queries filtering on the skewed parent return massive result sets
Reports aggregating child records under the skewed parent are slow or time out
