Do we have an In Memory Table something similar to the FeatureHolder but takes a dynamic schema?
Or is there a writer that can take dynamic schema without specifying a disk destination?

Perhaps the InlineQuerier is what you're looking for? It'll take input features (dynamic schema of course) and builds SQLite tables out of them upon which you can execute SQL queries and get the results back as FME features.
