This patch improves the transformencode optimizer by adding a sample-based estimation of the recode/partial recode map sizes. We fallback to full column recode build tasks if the partial maps do not fit in the memory. Future commits will fine tune the task graph with 1) column-specific build blocks counts and 2) serialized column-build tasks -- both based on the memory estimates. -- This is an automated message from the Apache Git Service.
