Moderately related, I have been working on a 'dictionary building' vector grouping strategy for string columns from my work related to vectorizing expressions, which I think is solving more or less the same problem (since string expressions also cannot use the dictionaryId as the grouping key). I think that might also be able to solve the lookup problem, though I haven't really thought about it very much yet in the context of lookups. I've been busy with some other stuff so haven't touched the code in over a month, but I think I should have a chance to wrap it up maybe next week, assuming testing goes as I hope. In the meantime, I'll try to think a bit more about lookups and if my work would truly be applicable here. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
