Google BigQuery V2 Connector

Fixed issues

The following table describes fixed issues:
Issue
Description
DBMI-24787
If you configured a proxy server but then tried to bypass it for Secure Agent communication with Google BigQuery targets by setting task_container.jvm.http.nonProxyHosts property at agent level, ingestion and replications jobs that have Google BigQuery targets might fail. The jobs fail because communication still goes through the proxy, and communications from the proxy are blocked a firewall.

Kafka Connector

Fixed issues

The following table describes fixed issues:
Issue
Description
DBMI-25753
For application ingestion and replication tasks and database ingestion and replication tasks that use a single topic for all writes to the Kafka target, the restart logic examines all Kafka topics instead of only the required topic, which might cause the task to fail if access to all topics is not allowed.
(October 2025)
DBMI-23577

Microsoft Azure Synapse Analytics Database Ingestion Connector

Known issues

The following table describes known issues:
Issue
Description
DBMI-19405
Tests of a Microsoft Azure Synapse Analytics Database Ingestion connection for an application ingestion and replication task or database ingestion and replication task fail with the following error if the user name specified in the connection properties includes a special character such as @ and the target database uses AAD authentication:
Cannot instantiate datasource because of error: Failed to initialize pool: Cannot open server 'noconline.onmicrosoft.com' requested by the login. The login failed. ClientConnectionId: <identifier>
This problem occurs because the Synapse Analytics connector package is missing some .jar files that are required to connect to the target database in this situation.
Workaround: Copy the following jars to the connector package:
  • - activation-1.1
  • - adal4j-1.4.0
  • - jcip-annotations-1.0-1
  • - json-smart-1.3.1
  • - mail-1.4.7
  • - nimbus-jose-jwt-9.40
  • - oauth2-oidc-sdk-5.24.1
The package location is: package-AzureDWGen2MI.xxx\package\dw\thirdparty\informatica.azuredwgen2mi
