Distributed systems are composed of multiple systems that are wired together to provide a specific functionality. Systems that operate at a cloud scale can get expected or unexpected surges of traffic from one or multiple callers and are expected to perform in a predictable manner. This article analyzes the effects of traffic surges on a distributed system.

Huge pages make PostgreSQL faster; can we implement it in Kubernetes? Modern servers operate with terabytes of RAM, and by default, processors work with virtual memory address translation for each 4KB page. OS maintains a huge list of allocated and free pages to make slow but reliable address translation from virtual to physical. Please check out the Why Linux HugePages are Super Important for Database Servers: A Case with PostgreSQL blog post for more information.

In my previous article ‘ Data Validation to Improve Data Quality ’, I shared the importance of data quality and a checklist of validation rules to achieve it. Those validation rules alone may not guarantee the best data quality. In this article, we focus on the best practices to employ while building the data pipelines to ensure data quality. 1. Idempotency A data pipeline should be built in such a way that, when it is run multiple times, the data should not be duplicated.

Observability platforms are akin to the immune system. Just like immune cells are everywhere in human bodies, an observability platform patrols every corner of your devices, components, and architectures, identifying any potential threats and proactively mitigating them. However, I might have gone too far with that metaphor, because till these days, we have never invented a system as sophisticated as the human body, but we can always make advancements.

Much has already been said about the importance of automated tests: they provide a great safety net when modifying system components, alerting to issues much earlier in the development lifecycle. As a result, bugs are prevented from ever reaching production environments. When we're working with legacy code that has very low automated test coverage (or no test coverage at all), building automated tests can be difficult and frustrating.

MongoDB is a schemaless database that is extremely flexible. When you create a collection, you don’t have to specify a structure in advance, providing field names and data types. Just start inserting JSON documents, and MongoDB will store them, no matter which fields and data types you provide. As a consequence, a collection can store completely different documents.
