Hi, Can you please confirm if there is any update regarding the hash tables use cases, as in [1] it is specified that Hash tables are used in Joins and for the Solution set in iterations (pending work to use them for grouping/aggregations)?
I am interested in the pending work progress and also if you consider to add an implementation where Joins and Solution Set in delta iterations (and CoGroup) can rely on a hybrid implementation where the engine can use also disk if not enough memory available when working with these hash tables.
