You must be aware of the following constraints before configuring the Salesforce Adapter.

• The Salesforce Adapter uses the SalesForceDotCom (SFDC) API for all activities. Therefore, it is subject to any Salesforce API limitations.
• Client applications must adhere to Salesforce’s SOAP API support policy and backward compatibility terms.
• Not all the push topic queries are supported by Salesforce.
• The platform events feature has the following restriction:
  • The maximum number of delivered event notifications within a 24-hour period, shared by all CometD clients:
    • 50,000 for Performance and Unlimited Editions
    • 25,000 for Enterprise Edition
    • 10,000 for Developer Edition
    See Platform Event Allocations.
• SOQL queries do not support the FIELDS() function to fetch data from Salesforce.com. Instead, explicitly specify all the fields needed in the SOQL query to get the data from accounts.
• You cannot use the Salesforce Adapter to publish events to Salesforce. However, you can use the Salesforce REST Adapter to satisfy this requirement.
• The Salesforce Adapter does not support the PushTopic and Generic Events.
