Optimising The Performance Of Power Query Merges In Power BI, Part 3: Table.Join And SortMerge

When you merge data from two queries in the Power Query Editor the M code generated uses the Table.NestedJoin function. There is, however, another M function that can be used to merge data: Table.Join. The interesting thing about this function is that has a parameter that Table.NestedJoin doesn’t have: the joinAlgorithm parameter allows you to specify the algorithm used by the Power Query engine for the merge.

Before we go any further, I don’t want you to go and change your reports if you’re not going to get any benefit from doing so. Use Performance Analyzer (as shown here) to determine which visuals on your report are the cause of slow performance – there’s no point redesigning visuals that are fast anyway.

Business Central – How to make it go FAST!

Microsoft in late January and early February published a series of pages on Microsoft Docs dedicated to performance with Business Central (On-premise, Cloud).
