What's new?

The following are the new features in 5.2.9:

• Limit prompt filters dashboard selection
• Analytics and Scheduler separation
• A new adjust offset TMT command
• Engine Concurrent Service Thread Throttling

Limit prompt filters dashboard selection

In this release, Incorta enables the Cluster Management Console (CMC) admin to restrict demanding execution queries by limiting the number of selections in a dashboard prompt filter that a dashboard consumer can apply. This limitation is applicable for the following prompt filter operators:

• In
• Not In
• Contains
• Does Not Contain
• Starts With
• Does Not Start With
• Ends With

You can find the new configuration in the CMC under Default Tenant Configuration > Incorta Labs > Max no. of selections for for string filter operators. The default value for the configuration is -1, which indicates an unlimited number of selections. 0 indicates an unlimited number of selections as well. Any number greater than 0 will indicate the maximum number of selections a dashboard consumer can select in a prompt filter.

For Contains, Does Not Contain, Starts With, Does Not Start With, and Ends With, the Select All option will not be available while creating filters. Instead, it is recommended to enter a custom-optimized string value to enhance filtration performance.

Analytics and Scheduler separation

Incorta has developed a new option to disable the scheduler on an analytics service. By disabling the scheduler, the admin eliminates any competition for resources between the scheduler and user queries. This ensures that the dashboard consumers have a dedicated analytics service solely for their queries.

In previous releases, the scheduler is always enabled on all analytics services. Starting this release, as a CMC admin, you can disable the scheduler while creating or editing an analytics service.

By disabling the Scheduler toggle, background jobs such as sending dashboards, load jobs, and scheduler jobs, run using the dedicated resources as per your infrastructure setup. Knowing that the Send Now feature in dashboards will work normally.

To enable or disable this option, you must apply the following steps:

1. Log into the CMC.
2. Navigate to Clusters > cluster_name > Nodes.
3. Select More Options (⋮ vertical ellipsis icon) next to the needed analytics service and select Edit.
4. Enable or disable the Scheduler option accordingly.
5. Go to the IncortaNode/services/{service-id}/incorta/service.properties file for each analytics service that you have, and add the following properties, making sure to add the port and IP numbers with the info for the analytics service that has the scheduler enabled:
   • local.server.host=<ip_address>
   • local.server.port=<port_number>
6. Restart the service for the change to take effect.

Tips and Tricks

• While setting up your infrastructure, you must keep in mind which analytics URL you share with your users in case you have multiple analytics services that have different scheduler enablement set up. It is recommended to share the URL of which the Scheduler option is disabled to maintain high availability.
• If you have a load balancer in place, make sure to configure it for the services that have the Scheduler option disabled.

A new adjust offset TMT command

Incorta is introducing a new tenant management tool command that aims to adjust the scheduler offset time during daylight saving time.

Command format:

Copy
./tmt.sh -clnm <clustername> -aofs <tenantName> <userName> --dry

For more information, refer to Tenant Management Tool → Adjust Offset Time for Scheduler.

Engine Concurrent Service Thread Throttling

A dashboard’s filtering can slow or be unable to render due to all Engine threads being used concurrently for another dashboard. With this resolution, workers will be throttled or increased based on the number of waiting jobs. Contact Incorta Support to edit the engine.properties file that exists in the Analytics Service directory and enable this feature.
