With Luminary’s 21 years of experience in the digital space, my experience of 17 years in the CMS space as well as our focus on Headless since 2016, here are my two cents on what you should look out for. From a developer perspective, not only static assets need to be cached on a CDN. Look out for: Caching of images and content via CDN.

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.

A reminder of the plan ( click to enlarge ): This is the first point in the process so far that an in-flight execution plan is available (SQL Server 2016 SP1 onward) in sys.dm_exec_query_statistics_xml. Additional parallel workers will be started to run the additional parallel tasks contained in branches B, C, and D. Starting Sequence.

Aurora Parallel Query response time (for queries which can not use indexes) can be 5x-10x better compared to the non-parallel fully cached operations. The second and third run used the cached data. It does not use any cache (ie: innodb buffer pool) either. This query is 100% cached. Test data and versions.

I presented this analysis of response time distributions talk in 2016 — at Microxchg in Berlin ( video ). > system.time(wait1 <- normalmixEM(waiting, mu=c(50,80), lambda=.5, Changes in behavior of the system from minute to minute is going to change the height of each peak, as the workload mix and cache hit rates change.

In September of 2016 we started noticing random failures when building Chrome – 3 out of 200 builds of Chrome failed when protoc.exe, one of the executables that is part of the build, crashed with an access violation. This was starting to look like a Windows file cache bug. failure rate. sync.exe after linking exes: 0% failure rate.

In the latest (October 2016) revision of Intel’s Instruction Extensions Programming Reference , Intel has disclosed a fairly dramatic departure from these “traditional” approaches. Notes on notation: C[i][j] is invariant in the innermost loop, so I refer to the values in the accumulator as elements of the C array.
