WebMar 4, 2024 · There is a similar thread, the user found that if he has an Int64 column with 225 000 rows, Vertipaq still uses a value encoding, but if it is ~ 240 000+ rows it uses dictionary encoding. Maybe it is the same logic for decimal columns. And he gave a solution: you can give a hint to the Vertipaq Analyzer, that it should use Value instead of Hash.

WebAfter all, for each value inserted into the parallel hashmap, we have to do some extra work (steps 1 and 2 below): compute the hash for the value to insert. compute the index of the target submap from the hash) insert the value into the submap. The first step (compute the hash) is the most problematic one, as it can potentially be costly.
