Hi all, As we discussed in [1], we need to decide whether to automatically filter out rows that are entirely null in the result set during a scan by the storage engine.
There are three reasonable options: [a] keep table model same as tree model ( automatically filter out rows that are entirely null ) [b] table model don't automatically filter out rows that are entirely null, but keep the tree model same as before. [c] table model and aligned time series in tree model don't automatically filter out rows that are entirely null, but keep nonAligned time series in tree model same as before Personally, I prefer [c], because in the storage engine, table model shares the same things as aligned time series in tree model, [b] will break it up while scanning. Feel free to vote for the option you personally want to choose. [1] https://lists.apache.org/thread/40gk1k1q3styjsf4s95ydlm5f2l2lcr4 Best regards, -------------------------- Yuan Tian
