Solved! Go to Solution.
@ganes There are a number of techniques for this but will depend heavily on what you are doing. For example, you could create aggregation tables so that you are not hitting the source system as often. You could try DirectLake in Fabric. You could also apply query reduction. Have you turned on "assume referential integrity" for relationships? You could also consider using a composite model. Or, you could use some third-party like AtScale and solve it that way.
