Data Integration: known issues and known limitations

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

https://jira.talendforge.org/issues/?filter=29826

Limitation

Description
 
  • 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
Java PSU is not supported. Talend is only supported on Java CPU Versions, not Java PSU.

Some users reported problems using Talend Studio with Java PSU versions (such as jdk8_u92), but when reverting to a Java CPU Version (such as jdk8_u91) the problem was resolved.

Collation limitation with Access Since 6.0, the Access components in Talend Studio support only the General collation mode.

OAuth mode in the Salesforce wizard

 To establish a Salesforce connection using OAuth2 authentication, you need first to execute a Talend Job to obtain your token file and then initialize it in the wizard.
tFileCopy can work only with Java 8 To prevent errors, users should run Jobs containing tFileCopy only on Java 8.

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.

Issue

Workaround
If Talend Administration Center works in clustered mode (two Talend Administration Center instances located on different physical servers but connected to the same database), context values may not be available in task execution details.Some SOQL queries are not supported for the guess schema and guess query features of tSalesforceInput. It is recommended to use shared folder in Job Conductor configuration which are available for all works in cluster mode.
