What is Greenplum Database? Intro to the Big Data Database

Scalegrid

Greenplum Database is a massively parallel processing (MPP) SQL database that is built and based on PostgreSQL. It can scale towards a multi-petabyte level data workload without a single issue, and it allows access to a cluster of powerful servers that will work together within a single SQL interface where you can view all of the data. In this blog post, we explain what Greenplum is, and break down the Greenplum architecture, advantages, major use cases, and how to get started.

A Short on How Zoom Works

High Scalability

Zoom scaled from 20 million to 300 million users virtually over night. What's incredible is from the outside they've shown little in the way of apparent growing pains, though on the inside it's a good bet a lot of craziness is going on. Sure, Zoom has made some design decisions that made sense as a small spunky startup that don't make a lot of sense as a defacto standard, but that's to be expected. It's not a sign of bad architecture as many have suggested.

DevSecOps: Recent experiences in field of Federal & Government

Dynatrace

Dynatrace news. Introduction. For Federal, State and Local agencies to take full advantage of the agility and responsiveness of a DevOps approach to the software lifecycle, Security must also play an integral role across lifecycle stages. Modern DevOps permits high velocity development cycles resulting in weekly, daily, or even hourly software releases. But outdated security practices pose a significant barrier even to the most efficient DevOps initiatives.

Difference Between Black-Box, White-Box, and Grey-Box Testing

DZone

You can never be sure about the quality of your in- development software unless you test it first. Conducting a thorough analysis of whether your software meets all the requirements, whether it is secure, responsive, complete, and easy to use is crucial to avoiding technical debt and making sure your software is well received after the release. And this is exactly what testers do for you. Software testing is a process of investigation.

Fundamentals of table expressions, Part 2 – Derived tables, logical considerations

SQL Performance

Last month I provided a background to table expressions in T-SQL. I explained the context from relational theory and the SQL standard. I explained how a table in SQL is an attempt to represent a relation from relational theory. I also explained that a relational expression is an expression operating on one or more relations as inputs and resulting in a relation. Similarly, in SQL, a table expression is an expression operating on one or more input tables, and resulting in a table.

Tracking Web Vitals for a better user experience

Speed Curve

Google recently announced an initiative called 'Web Vitals', which focuses on three performance metrics they consider essential for improving the user experience: Largest Contentful Paint (LCP). First Input Delay (FID). Cumulative Layout Shift (CLS). With the exception of FID, all of these metrics are available in both LUX (our RUM tool) and Synthetic. FID requires a real user for calculation and therefore is only available in LUX.

SQL Plan Management With TiDB: A Review

DZone

The SQL execution plan is a critical factor that affects SQL statement performance. The stability of the SQL execution plans heavily influences the entire cluster's performance. If a relational database's optimizer chooses a wrong execution plan for a query, it usually has a negative impact on the system; for example, operations might take longer to respond or the database might get overloaded. We've done a lot of work on optimizer stability for TiDB.
