1. What is Data Skew in Salesforce and how can we avoid this?
Ans:- Data skew happens when more than 10000 child records are related to a single parent record, or more than 10000 records of any object are owned by a single user. Two types of DATA SKEW are there in Salesforce.

• Account Skew (Having more than 10000 records under a single parent account)
