Use MOSdestroy trick for that. Make dictionary variable-sized so it can always compress. We are going to use vheap for this. dictionary encoding should use the ordered property of its dictionary in the algebraic operators -decouple estimation completely from compression: there should be two runs: one for estimating the blocks and one to actual compress according to the estimations. Test null semantics mosaic.select (c,nil:any_1, nil:any_1,true,true,(true|false)) is not working correctly: should result in c == nil or c!=nil(anti). Use bit vectors more aggressively in mosaic_delta --- then resolve test mosaic_delta_timestamp --- and possibly other compression techniques as well. Somehow force mosaic to only use specified compressions even if inefficient. This poses a design problem for dictionary compression though. Be sure alignment is correct. Use asserts for this. -fix layout call. +Check MOSanalysis and its test. +Fix/check/test MOSlayout. Add test for float/double delta compression: check if the hardcoded compression expression are correct. See also (2) Add asserts on type degeneration for bit => bte daytime => lng timestmap => lng date => int. Fix the task-factor array. See if we can re-introduce landmark stuff somehow. -Fix/check/test MOSlayout. benchmark Do estimation before mosaic heap creation.That saves a potential heap extend. _______________________________________________ checkin-list mailing list checkin-list@monetdb.org https://www.monetdb.org/mailman/listinfo/checkin-list
