Now, the connector allows bulk sampling to proceed by skipping tables with timestamp_ntz, void, and interval issues. (AL-146049)
Azure Synapse Analytics OCF Connector: Version 1.2.6¶
Fixed Issues¶
QLI for Serverless Pool Works Only When Connected to Master Database¶
QLI in Azure Synapse Analytics OCF connector fails to extract queries when connected to any database other than the master database as the queries executed in Azure Synapse are logged only to the master database.
Now, when you execute serverless pool QLI, a new connection is established to the master database to extract queries.(AL-145689)
Databricks on Google Cloud OCF Connector: Version 2.0.3¶
Fixed Issues¶
Bulk Sampling Fails for Column Data Types timestamp_NTZ, Void, and Interval¶
For example, for Databricks on Google Cloud data source, sampling fails with the following error for column data type timestamp_NTZ:
The connector was provided with a list of columns to profile from a table, however the schema of the returned result set did not match those columns.
Now, connector allows bulk sampling to proceed by skipping tables with timestamp_ntz, void, and interval issues. (AL-146052)

Enhancements¶
Removal of ORDER BY Clause in Default Metadata Extraction Queries¶
The ORDER BY clause has now been removed from the default Metadata extraction queries.
Processes subsequent to MDE ensure the extracted objects (Schema, Table, and Column) are mapped to the correct hierarchy. Therefore, it is redundant for the connector to fetch ordered items from the data sources. (AL-149896)
Fixed Issues¶
Metadata Extraction Fails¶
Metadata extraction fails with the following redundant error message:
MissingFormatArgumentException: Format specifier ‘%s
The connector has now modified the error handling to display appropriate error messages during MDE failure. (AL-147543)

Now, the message is displayed only when the daily average query volume exceeds the 500K threshold. (AL-141936)
Fixed Issues¶
Upload Data Fails for Column Data Type timestamp_NTZ¶
For Snowflake data source, the Upload Data action fails with the following error for the column data type timestamp_NTZ:
The uploaded data does not seem to match the selected table
Now, you must ensure that you run MDE before you try the Upload Data action again. (AL-138612)
Custom QLI Query Validation Fails If the ENDTIME Keyword Appears Before the STARTTIME¶
Including the STARTTIME and ENDTIME keywords in the Custom QLI queries is mandatory. However, the connector restricts users from using the ENDTIME keyword before the STARTTIME keyword within a custom query. This results in a validation error for the custom QLI queries that require the ENDTIME keyword to appear before the STARTTIME keyword and the user cannot save it.
Now, the connector allows the users to successfully save the custom QLI query irrespective of the STARTTIME or ENDTIME keyword order. (AL-149456)
March 06, 2024¶
Amazon Redshift OCF Connector: Version 1.8.1¶
Fixed Issues¶
Custom QLI Query Validation Fails If the ENDTIME Keyword Appears Before the STARTTIME¶

Compatible Alation Version - 2022.4 or higher
Enhancements¶
The allowUnderscoresInHost Parameter is Automatically Set in the JDBC URI¶
If you miss setting the allowunderscore parameter in the JDBC URI field on the General Settings tab of the Snowflake data source, the Snowflake OCF connector automatically sets the allowunderscore parameter to true (allowunderscore=true).

SQL Server OCF Connector Version 1.3.7¶
Compatible Alation version: 2022.2 or higher
Fixed Issues¶
Connection Test Fails When Using SSL with NTLM Authentication¶
Fixed an issue when the connection test failed when SSL was enabled with NTLM authentication. The test resulted in the following error:
Caused by: sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
To use SSL with NTLM, basic, or Kerberos authentication, use the following JDBC URL format:
sqlserver://<Host_Name>:<Port_Number>;encrypt=true;hostNameInCertificate=<certificate_name>;
This JDBC URI includes the following additional SSL related parameters:
encrypt=true
hostNameInCertificate=<certificate_name>
You can run the command below to verify your certificate name. In the result, check for the value after CN=. That’s the certificate name.
openssl x509 -noout -subject -in <certificate_name>.crt;
Example:
sqlserver://10.13.82.165:1433;encrypt=true;hostNameInCertificate=abc.corp.net;
