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.

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. All functionality and integrations would also have a tight dependency which in turn results in a large, cumbersome monolithic code base.

From SQL Server 2016 onward, FastLoadContext is enabled by default ; the trace flag is not required. For more background, see the Data Performance Loading Guide and the Tiger Team notes on the behaviour changes for SQL Server 2016. FastLoadContext can be disabled on SQL Server 2016 using documented trace flag 692. The sqllang!CUpdUtil::FOptimizeInsert

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.

Because of its history and for being sort of a fork of an old blogging platform called “b2” (more details here ), it’s largely written in a procedural way (using function-based code).

This was a keynote presentation at the “2nd International Workshop on Performance Modeling: Methods and Applications” (PMMA16), June 23, 2016, Frankfurt, Germany (in conjunction with ISC16 ). Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

For this page to be done loading it needs to be responsive to user input — the “interactive” in “Time to Interactive” Browsers process user input by generating DOM events that application code listens to. Any DOM or UI created in JS is not available for use until the script runs. Execute the script.

In the latest (October 2016) revision of Intel’s Instruction Extensions Programming Reference , Intel has disclosed a fairly dramatic departure from these “traditional” approaches. With 2 FMA units that have 5-cycle latency, the code must implement at least 2*5=10 independent accumulators in order to avoid stalls.

Let’s say we wanted to reuse some of the code from our previous project in our next one. While static libraries allowed us to reuse source code, static linkage does not allow us to reuse memory for executable code between different processes.

A component is simply a set of pieces of HTML, JavaScript and CSS code put all together to create an autonomous entity. Hence, the API can be implemented on any language (which is one of the beauties of GraphQL: being a specification and not an actual implementation has enabled it to become available in a myriad of languages.).
