However, this blog is written from the database perspective; hence, I would not prefer to dive into those scenarios as they are very high-level programming concepts. In this section, I will focus on a scenario in the PostgreSQL database that causes segmentation fault. At present, this is in the development phase.

Data powers everything, and unlike coal and coal combustion, data and databases aren’t going away. In this blog, we’ll focus on the elements of database backup and disaster recovery, and we’ll introduce proven solutions for maintaining business continuity, even amid otherwise dire circumstances.

Additionally both commercial and open source tools based on the specifications also continued to use TPC-C and TPC-H to describe these workloads. A full understanding of why this is important requires some knowledge of the evolution of database hardware and software. But why is this important?

To make data count and to ensure cloud computing is unabated, companies and organizations must have highly available databases. A basic high availability database system provides failover (preferably automatic) from a primary database node to redundant nodes within a cluster. HA is sometimes confused with “fault tolerance.”

Unfortunately, using certain open source database software as part of an HA architecture can present significant challenges. Despite all its upside, PostgreSQL software presents such challenges. This blog highlights considerations for keeping your own PostgreSQL databases highly available and healthy.

Every database system has to ensure durability and reliability. ” This acts as a step to ensure durability by recovering lost data from the same journal files in case of crashes, power, and hardware failures between the checkpoints (see below) Here’s what the process looks like. These checkpoints are stored in WiredTiger.wt

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.”

This discussion focuses on hardware, software and operational failure modes. When there’s three ways to succeed, we still have two ways to succeed when a failure is present, and if data is corrupted, we can tell which of the three is the odd one out. There is no need to retry and no extra time taken when a failure is present.

As OS and hardware deployed base integrate these components, the set of what most computers can do is expanded. This is often determined by hardware integration and device replacement rates.

Rather than listing the concepts, function calls, etc, available in Citus, which frankly is a bit boring, I’m going to explore scaling out a database system starting with a single host. I won’t cover all the features but show just enough that you’ll want to see more of what you can learn to accomplish for yourself.
