Hi @Marek_Bisztyga,
Welcome to MongoDB community!
Compass allows you to use a sample mode in the aggregation builder therefore you should be able to construct your pipeline in compass and use the “export” button in the end.
Only in 4.4 you can add the allowDiskUse is allowed in find.
The {allowDiskUse: true} should be added to the query/aggregate command used on the already defined view therefore it cannot be done as part of the agg builder.
Hope that helps.
Best
Pavel
