To prevent large queries from crashing the app server, Data 360 limits Salesforce Object Query Language (SOQL) results to 12-MB. SOQL returns the results up to the size limit with a query more link to paginate through the rest of the results. If a single query result exceeds the size limit, SOQL rejects the query and you can’t retrieve the results.
