>            Priority: Minor
> The inverted index tests take up the majority of the time spent in the Hyracks tests
(~25min out of 33min). Taewoo looked into this and discovered that the reason is at least
partially because of the parameters in AccessMethodTestsConfig . Those parameters are not
taking into account that queries on an inverted index will be far more expensive, because
they are all point lookups. It just uses roughly the same number of operations as the BTree/RTree
> We may want to lower the number of operations, or perhaps there is some other performance
improvement that may ameliorate this situation.
