Release Notes

We encourage you to consult the JIRA bug tracking tool for a full list of open issues:




  • the SOQL query using the aggregate function
  • the SOQL query using the TYPEOF expression
  • the SOQL query using alias
  • Some SOQL queries are not supported for the guess schema andthe prefix in the SOQL query is the same as the module name after FROM

    For example, SELECT Account.Name, (SELECT Contact.LastName FROM Account.Contacts) FROM Account is not supported, while SELECT Name, (SELECT LastName FROM Contacts) FROM Account that performs the same function is supported.

  • the SOQL query with multiple modules after FROM

    For example, SELECT Contact.Firstname, Account.Name FROM Contact,Contact.Account is not supported. However, the child-to-parent and parent-to-child relationship queries are supported, so this query can be improved to SELECT Firstname, Account.Name FROM Contact.

  • the SOQL query using toLabel()
  • the field with the underscore character '_' in its name

Talend Data Services Platform

tParallelize in the context of Routes and Data Services Jobs

The tParallelize component is designed for Data Integration Jobs. Do not use it in the context of Data Services Jobs or Routes because it is not thread safe between parallel requests and will cause huge memory and CPU consumption. Use a Route if parallel processing is a requirement.
