Incremental data loading with Azure Data Factory and Azure SQL DB

Here is a super easy way to tell ADF to only query for row updates from your Azure SQL Database sources without needing any set-up. Let ADF handle the watermark and query for you using "Enable incremental extract".

Another question on this feature: Is it possible to dynamically via "Copy Data" using the incremental load feature. In this video it show how it can be done on a source via Data Flow but I would like to use Copy Data in a Pipeline with the ability to only copy new data. Possible?

great new feature wonder how it would perform with a large volume of data

Super new feature !!! Does this applies to all data sources ? Or it is specific to Azure sql database as source ?

[agratu]

My source is JSON (Mongo) and Destination is SQL tables (for each array in JSON I am creating a separate table). In this case how to do incremental load for each table ?

[cjchinmay]

this was great ! I had one question: We are working on a project where we have CDM as a source and SQL server as the target. After the initial load, how can we implement incremental load for the same for the CDM format?

@azure data factory, Do we have a video as MongoDB as source and incrementally load to azure datalake for powerbi to consume. Need near to realtime data or every 10mins, Not all data but only load changed/new data to azure datalake

I neglected to ask. Would this work for Serverless SQL Pool views?

[VikingGuard]

In dataflow is there any limits on number of columns?

[ramyakumari]

If we don't have last modified date or time stamp column, how to find out updated columns?

[NicolasJohnson]

Where is the timestamp stored? What if you use a dynamic/generic source?

[Cheyenne]

I love the feature. What if we need to do a full reload. How can we reset the date?

[benediktbuchert]

When is the incremental loading reset? Does it happen if I do a change to the flow or pipeline? Can I reset it manually?

[NeumsFor]

Boy would it be great if this could be expanded to handle and
incremental integer value like a Kimball Audit a compound business key that auto generated an ordered, correlated subquery....not unlike the what is in the SSIS Operational and tuning guide. Of course there would need to be options to work through with the latter.

By doing that it would also facilitate checkpoint restart within a data flow. Two birds with one stone, but it could get complex.

Lol it doesnt work for incremental load from gen2 to staging

[dylanmccullough]

fantastic. When was this feature released?
