Are there any videos, demos, or demonstrated use case for using Talend Data Catalog and showing its use and capabilities instead of the learning paths on learning portal?

Setup

We created a Mixpanel connector pointing to our Mixpanel project, configured with:

• Historical backfill start date: 10 Aug 2025 (approximately one year of data)
• Replication schedule: daily

What we observed

We triggered a manual run to load the historical data. That run continued for 24 hours without completing the historical sync, and was still in progress when the next scheduled run was triggered.

The following day's run did not resume from where the previous run stopped. It started again from the beginning and attempted to load the entire year of historical data from scratch. This repeated for several days. On some days the Mixpanel API errored partway through, which also forced the next run to restart from the beginning.

Impact

Across those few days, more than one billion rows were loaded, the large majority of which are duplicates of the same historical data re-ingested on each run. The connector never advanced far enough to reach current data.

What we would like to understand

1. Why does the connector behave this way — specifically, why is progress from an incomplete run not retained, so that each subsequent run restarts from the original start date rather than resuming?
2. What is the recommended way to configure this connector so the historical backfill completes reliably and the pipeline then stays current — without re-ingesting the same data on every run?

Good afternoon, community.

I am creating a report in which I am using a `ValueList` within my dimension—for example: `ValueList('RESULTADO 2026', 'VS 2025', 'VS KPI 2026')

And in my measure, I include this formula:

=If(
ValueList(
'RESULTADO 2026',
'VS 2025',
'VS KPI 2026'
) = 'RESULTADO 2026',

Num(Sum({<Mes=,Año = {'$(vAñoActual)'},fecha = {"<=$(vMaxFechaActual)"}>} Numero_Entradas),'#,##0'),

If(
ValueList(
'RESULTADO 2026',
'VS 2025',
'VS KPI 2026'
) = 'VS 2025',

Num((Sum({<Mes=,Año={'$(vAñoActual)'},fecha = {"<=$(vMaxFechaActual)"}>} Numero_Entradas) - Sum({<Mes=,Año={'$(vAñoAnterior)'},fecha = {"<=$(vMaxFechaAnterior)"}>} Numero_Entradas))
/Sum({<Mes=,Año={'$(vAñoAnterior)'},fecha = {"<=$(vMaxFechaAnterior)"}>} Numero_Entradas),'0.0%'),

Num((Sum({<Mes=,Año={'$(vAñoActual)'},fecha = {"<=$(vMaxFechaActual)"}>} Numero_Entradas)/Sum({<Mes=,Año={'$(vAñoActual)'},fecha = {"<=$(vMaxFechaActual)"}>}Total_Presupuesto)),'0%')
)
)

If I don’t select a specific month, my results appear correctly in the report. However, if I select a month—for example, September—the data for September is displayed correctly, but the data for the preceding months is shown as percentages instead of the correct values.
The measure I am using represents a cumulative total from January to September.
How can I ensure that, when I select a specific month, the data for the unselected months is also displayed correctly?

I have attached images showing how my report looks.

I look forward to your suggestions.
Thanks.

Hi all,

In Qlik Cloud Analytics I created a data alert that triggers when the supplier changes for an item-warehouse combination. The alert works, but the View in application link in the notification fails to apply the selection.

Setup

• The alert is created from a master dimension that is a plain field (no expression), and it has measures Sum(SupplierChanged), Only([Previous Supplier]) and Only([New Supplier]).
• The alert is split by that dimension under Show by dimension.
• Condition: Supplier Changed Flag greater than 0. Schedule: when data changes.
• The notification itself is correct: it lists the key and the old and new supplier.

Problem
Clicking View in application opens the app and shows:
“A field you are trying to make a selection in could not be found. The selection has not been applied.”

Link generated from the alert - .../sheet/<sheetId>/bookmark/<bookmarkId>/select/[ItemWarehouseKey]/400000021000001-1CH

What I tested

• Editing the first link to remove [ ] so it ends /select/Item%20Warehouse%20Key/400000021000001-1CH opens the app with the key selected correctly. The field and data are fine.
• Recreating the alert from scratch, with a plain-field master dimension and with a field name without spaces, did not remove the brackets.
• Test with brackets and no =: [fails]
• Test without brackets: [works]

Questions

1. Does the data alert link support a selection on a field when the alert is split by a master dimension or table dimension? Is it expected to include =[ ] or [ ] in the link?
2. Is there a way to make the alert write the plain field name in the link?
3. Is this a known limitation or a bug?

Hi Qlik Community, 

¡IMPORTANT!

If you are on QAP and leverage anonymous authentication, do NOT upgrade to May 2026 Initial Release.

We have upgraded one of our TEST environments and noticed this issue:

even if the Virtual Proxy is configured to Allow Anonymous Users, they are being prompted for authentication.

So, please check your virtual proxy configuration before upgrading, or wait for the fix.

The Virtual proxies that are configured as Always anonymous users are working as expected.

Hi Support,

In the GetTableStatuses QEM API call which monitors Replicate tasks, there are 3 metrics returned in the response body called cached_insert_count, cached_update_count and cached_delete_count.  

I'd just like to understand the meaning of these metrics further. Do the counts represent the inserts/updates/deletes that have been picked up from the source and are yet to be applied to the target (i.e. in flight changes)? Or are they a historical count of all cached inserts/updates/deletes?

Thanks,

Nak

Hello everyone,

I’ve been thinking about the possibility of converting some of the scripts I use in various apps into semantic models. It is possible to convert a data-loading script that results in a data model into a semantic model?

I do'nt know if it is possible (yet?), at least I haven't found it...but it would be amazing.

Thanks in advance

Hi all,

we are experiencing an issue with a Qlik Replicate Full Load from MariaDB to SQL Server.

The source table is very large, containing approximately 7.6 billion rows.

The load fails while Replicate tries to create the primary key/unique index on the target table:

Stream component 'st_1_TargetEndpoint' terminated
Stream component failed at subtask 1, component st_1_TargetEndpoint

Error executing data handler
