Faster (more scalable) DataSet.Merge?

Question

We use strongly typed DataSets in our application. When importing data we use the convenient DataSet.Merge() operation to copy DataRows from one DataSet to another.

Answer 1

You've probably already tried this, but just in case:

DataSet.Merge takes an array or DataRows as a parameter.

Have you tried batching the merge, i.e. doing the following?

dataSet1.Merge(lines.Select(line=>ImportRow(line)).ToArray());

However, it's quite possibly the case that you cannot improve performance - maybe you can avoid the need to Merge in the first place somehow - such as by doing the merge in the DB, as Sklivvz suggests.
