Release notes

The following are the release notes for Striim Cloud 4.2.0.

Changes that may require modification of your TQL code, workflow, or environment

  • Starting with release 4.2.0, TRUNCATE commands are supported by schema evolution (see Handling schema evolution). If you do not want to delete events in the target (for example, because you are writing to a data warehouse in Append Only mode), precede the writer with a CQ with the select statement SELECT * FROM <input stream name> WHERE META(x, OperationName) != “Truncate”; (replacing <input stream name> with the name of the writer's input stream). Note that there will be no record in the target that the affected events were deleted.Handling schema evolution

  • If you are using MSJet, Contact Striim support for additional files required to resolve known issue DEV-37025.

  • MongoDB Reader no longer supports MongoDB versions prior to 3.6.

  • MongoDB Reader reads from MongoDB change streams rather than the oplog. Applications created in earlier releases will continue to read from the oplog after upgrading to 4.2. To switch to change streams:

    1. Export the application to a TQL file.

    2. Drop the application.

    3. Revise the TQL as necessary to support new features, for example, changing the Connection URL to read from multiple shards.

    4. Import the TQL to recreate the application.

  • Databricks Writer's Upload Policy's default eventcount value has been increased from 10000 to 100000 (see Databricks Writer properties).

Resolved issues

The following previously reported known issues were fixed in release 4.2.0:

  • DEV-31993: control characters in DDL statements cause application to halt

Known issues

  • DEV-5701: Dashboard queries not dropped with the dashboard or overwritten on import

    When you drop a dashboard, its queries are not dropped. If you drop and re-import a dashboard, the queries in the JSON file do not overwrite those already in Striim.

    Workaround: drop the namespace or LIST NAMEDQUERIES, then manually drop each one.

  • DEV-8142: SORTER objects do not appear in the UI

  • DEV-8933: DatabaseWriter shows no error in UI when MySQL credentials are incorrect

    If your DatabaseWriter Username or Password values are correct, you will see no error in the UI but no data will be written to MySQL. You will see errors in webaction.server.log regarding DatabaseWriter containing "Failure in Processing query" and "command denied to user."

  • DEV-11305: DatabaseWriter needs separate checkpoint table for each node when deployed on multiple nodes

  • DEV-17653: Import of custom Java function fails

    IMPORT STATIC may fail. Workaround: use lowercase import static.

  • DEV-19903: When DatabaseReader Tables property uses wildcard, views are also read

    Workaround: use Excluded Tables to exclude the views.
