   1. If this is a Two-Phase read query, and we need to delay the release of 
BetaRowsetReader by holding references in QueryContext. This is necessary to 
avoid data loss during the second phase reading, where some stale rowsets may 
be swept and result in missing data.
   2. For rowsets that have been moved to the unused rowsets, they are also 
needed in second phase reading.
