Release Notes 5.2.6

The 5.2.6 release introduces the new query timeout feature. In addition, there are several enhancements and fixes that aim to stabilize Incorta and enhance its performance.

Upgrade considerations

Incorta has implemented an enhancement to address SQLi queries involving user-defined or unresolved joins within Incorta Engine. In scenarios where the Engine cannot identify a suitable query plan, it falls back to Spark and executes the original user-defined query. However, it's important to note that as a result of these improvements, the outcomes of existing queries may vary compared to previous releases. To maintain consistency with previous results, it is recommended to review these queries accordingly.

What’s new?

Query timeout

New configurations are now available in the Cluster Management Console (CMC), Tenant Configurations > Tuning > Query timeout and Query timeout (in minutes), to set a time limit after which running queries will be terminated automatically, releasing the read lock acquired on the related entities and freeing the resources reserved by these queries. These configurations affect querying data in the following scenarios:

  • Creating an insight
  • Rendering a dashboard
  • Sending a dashboard via email or to a data destination
  • Downloading a dashboard as CSV or Excel
  • Previewing a chart as a listing or aggregated table
  • Creating or updating an Incorta Analyzer table or view
  • Exploring the data of a table or view
  • Creating a data notification condition

The system tracks queries that are automatically terminated, and it records them in the system logs. In addition, a message will be displayed if applicable.

Zookeeper logging enhancements

Incorta enhanced the zookeeper logging for better performance. Starting this release, you can find the zookeeper logs in the IncortaNode/zookeeper/logs directory.

Incorta creates three files as follows:

File nameDescription
zookeeper.logIt has the information log level for zookeeper.
zookeeper_trace.logIt has the trace log level.
zookeeper_audit.logIt has the audit log data if it's enabled.
You can enable it by setting the configuration in the IncortaNode/zookeeper/con/zoo.cfg file.

Incorta rolls the zookeeper log files as follows:

  • Incorta creates a separate log file for each day.

  • If the log file size exceeds 1GB, Incorta creates a new log file for the same day and archives the previous one in the following format: <file-name>.<date>.log.gz.

    Note

    If your log files need to be more than 1GB, please contact Incorta Support. If there is more than one archived log file for the same day, override the previous one.

  • At the end of each day, Incorta archives the log file in a .gz format. The naming convention for the archived logs is <file-name>.<date>.log.gz.

  • Incorta keeps an archived log file for 10 days only. Afterward, it deletes the oldest log file automatically.

Enhancements and Fixes

In addition to the enhancement mentioned above, this release introduces other enhancements and fixes that help make Incorta more stable, engaging, and reliable.
