Hardware considerations The first thing we have to consider here is the resources that the underlying host provides to the database. Global memory caches are static in size as they are defined solely by the configuration of the database itself. Let’s take a look at each common resource.

I can see from the screenshot above that TTFB is my most stable metrics—no one page appears to have particularly expensive database queries or API calls on the back-end. The whole point of the exercise that follows is to allow me to move quickly, spotting patterns from afar, and not having to do any slow or meticulous work yet.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

Today marks the 10 year anniversary of Amazon's Dynamo whitepaper , a milestone that made me reflect on how much innovation has occurred in the area of databases over the last decade and a good reminder on why taking a customer obsessed approach to solving hard problems can have lasting impact beyond your original expectations.

Application performance monitoring focuses on specific metrics and measurements; application performance management is the wider discipline of developing and managing an application performance strategy. Causes can run the gamut — from coding errors to database slowdowns to hosting or network performance issues. APM’s many forms.

Performance is one of the essential aspects of a database management system. One way to verify a column’s number of distinct values is by querying the pg_stats view in our database. One of the most effective ways to tackle performance improvement is having the proper indexes for the table columns. Next is the table definition.

There are many possible failure modes, and each exercises a different aspect of resilience. Next you record what effect you expect your mitigation strategy to have, which should drop its RPN and then let you focus on the new highest RPN, until there aren’t any high values left. that are used across multiple applications.

The deployment of connection-aware routing reduced query-load on backend databases by 17%, compared to a baseline implementation using Social Hash alone. Our solver employs a local search algorithm using the “best single move” strategy. We looked at this before when we studied Facebook’s Social Hashing algorithm.

In addition to that, software is increasingly dependent on other software to provide its functionality, be it WebServices, HTTP APIs, databases, or even external devices such as sensors. Its strategies for flow control are either stop-and-wait (i.e., HTTP, TCP, FTP, MQTT, JMS), databases (i.e., The need for flow control.
