Description
When the snapshot query is planned, there are cases to look up completion time based on instant time, which can be a performance bottleneck, especially there are huge number of files, and large number of instants to look up, in both archived and active timeline. We should see if this can be improved by storing the completion time of each file in the FILES partition in the metadata table to avoid expensive lookup every time. When the completion time of each file in the FILES partition is stored in MDT, we only need to do filtering based on the information from MDT only.
