Explanation:

The Sforce-Enable-PKChunking header enables you to extract large data sets from Salesforce by using a technique called primary key (PK) chunking. PK chunking splits your query into multiple queries based on the record IDs of the queried object.This reduces the query time and avoids the query timeout issues that can occur with large data volumes
