BEST PRACTICES TO FOLLOW WHILE DEBUGGING A BATCH CLASS

Best Practices to follow While debugging a batch class:

• Remove unnecessary code and loops

• Efficient use of collections (Set, Hashmap or List)

• Avoid using loop within loop

• SOQL query should be indexable

• Avoid unnecessary re-initialization of variables

• Use Aggregated SOQL (as Database operations not counted in this limit, avoid arithmetic operations in Apex)

• Check how much time Workflow rules and process builders are taking

• Is there any manage package performing heavy operations in transaction
