Is it possible to concatenate two datasets in AWS QuickSight?

0

I have several datasets uploaded from xlsx files that have matching column names. Is it somehow possible to concatenate/unify these datasets into one?

I tried to do this in Datasets > Edit Dataset > Add data, but there the only option for merging several datasets together was a join operation.

Example: if I have a dataset with M -rows and N-columns and another one with M2 Rows and N columns, I would like that the final dataset after concatenation would be M + M2 rows and N columns

Can you clarify if you are trying to join theses on Analysis o datasource section?

  • Well I do not really mind if the concatenation is done on analysis or dataset level. Example: if I have a dataset with M -rows and N-columns and another one with M2 Rows and N columns, I would like that the final dataset after concatenation would be M + M2 rows and N columns

  • please post this type of answers as comments to the question.

you can use calculated fields for that - it can be done on analysis or dataset level https://docs.aws.amazon.com/quicksight/latest/user/adding-a-calculated-field-analysis.html

  • How does this help me? I do not want to add any new fields to the dataset, but I want to basically row-join two datasets. Example: if I have one dataset with M rows and N columns and another with M2 rows and N columns, I would like the final dataset after concatenation to have M + M2 rows and N columns.

  • the user is asking for the ability to make a Union between 2 datasets, not to add a concatenate function as calculated field.

Your best bet might be to create Athena tables for each dataset, use Athena to create a 'view' that is a union all, then import that view into QuickSight.
