Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged. Table-valued functions use a table variable, which can be used to cache and replay results in suitable circumstances. Spools are the least costly way to cache partial results.

Cache Your Images. A website’s performance can suffer if frequently accessed images are not cached, as many requests will be made to images that have already been loaded in the user’s system. But not only does it cache the original image, but it also stores all the transformations and combinations we make from it.

The general idea is to cache and replay results, saving repeated executions of inner-side operators wherever possible. When a spool is able to replay cached results, this is known as a rewind. You may find it helpful to think of a spool rebind as a cache miss, and a rewind as a cache hit. Lazy Table Spool. Rule Matching.
