Subj:   Re: Perf Issues in Empty partition Scan
 
From:   Walter, Todd

1. Collect stats on PARTITION each time new partitions are populated. This will give the optimizer information it needs to estimate how much data will come from the open ended range.

2. There is no cost to reading the empty partitions with a scan. There is no data , no structure, nothing to read so it costs nothing.
