This has to do with the fact that currently, SQL Server doesn't support an efficient combination of parallel order-preserving index operation prior to a parallel batch mode Window Aggregate operator. It's curious the optimizer chose one strategy for the demand intervals and another for the supply intervals.

Shift-left speeds up development efficiency and reduces costs by detecting and addressing software defects earlier in the development cycle before they get to production. Likewise, shift–right is the practice of performing testing, quality, and performance evaluation into production under real-world conditions.

However, performance test execution and evaluation shouldn’t be a manual process and certainly shouldn’t be limited to dedicated testing teams. Zero-downtime deployment strategies such as blue/green or canary releases introduce built-in recovery mechanisms to reduce the impact of defects on production users.

Using a connection pool in each module is hardly efficient: Even with a relatively small number of modules, and a small pool size in each, you end up with a lot of server processes. Our tests show that even a small number of clients can significantly benefit from using a connection pooler. The architecture of a generic connection-pool.
