SQL Server will ship Azure SQL Database Edge: [link]. As you can imagine, with a code base as large and vast as SQL Server, there is always room for improvement. For example, Azure SQL Database Edge can already use TSQL Predict Machine Learning (ML) and Column Storage. Reduce the number of partitions and size of the cache.

For each database that has pages in the buffer pool, there is a hash list of pages, in page ID order, that’s quickly searchable to determine whether a page is already in memory or whether a physical read has to be performed. And the more pages in memory for a database, the longer the scan would take. ) ; GO.

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.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? It’s much easier to reach performance goals when the code base is fresh or is just being refactored.
