Change subject: [rowset_metadata] add min/max encoded keys update during restart ...................................................................... [rowset_metadata] add min/max encoded keys update during restart We can cache the encoded min/max keys in rowset metadata to help bootstrap tablets without having to fully initializing the CFileReaders for the key columns of each rowset. However, we can only update the min/max encoded keys during insert or update operations right now. This means that if we didn't save the min/max encoded key before, we won't have the opportunity to use this feature to accelerate bootstrap in the future. Considering that we will read the min/max key values during the bootstrap process, we can set the min/max encoded keys in the metadata at the same time. I added a small case to ensures we can get the same keys from the bootstrap process at startup.
