Column by your name: The analytics database that skips the rows
These days, every company looking at analyzing their data for insights has a data pipeline setup. Many companies have a fast production database, often a NoSQL or key-value store, that goes through a data pipeline.The pipeline process performs some sort of extract-transform-load process on it, then routes it to a larger data store that the analytics tools can access. But what if you could skip some steps and speed up the process with a database purpose-built for analytics?On this sponsored episode of the podcast, we chat with Rohit (Ro) Amarnath, the CTO at Vertica, to find out how your analytics engine can speed up your workflow. After a humble beginning with a ZX Spectrum 128, he’s now in charge of Vertica Accelerator, a SaaS version of the Vertica database. Vertica was founded by database researcher Dr. Michael Stonebreaker and Andrew Palmer. Dr. Stonebreaker helped develop several databases, including Postgres, Streambase, and VoltDB. Vertica was born out of research into purpose-built databases. Stonebreaker’s research found that columnar database storage was faster for data warehouses because there were fewer read/writes per request. Here’s a quick example that shows how columnar databases work. Suppose that you want all the records from a specific US state or territory. There are 52 possible values here (depending on how you count territories). To find all instances of a single state in a row-based DB, the search must check every row for the value of the state column. However, searching by column is faster by an order of magnitude: it just runs down the column to find matching values, then retrieves row data for the matches. The Vertica database was designed specifically for analytics as opposed to transactional databases. Ro spent some time at a Wall Street firm building reports—P&L, performance, profitability, etc. Transactions were important to day-to-day operations, but the real value of data came from analyses that showed where to cut costs or increase investments in a particular business. Analytics help with overall strategy, which tends to be more far-reaching and effective. For most of its life, Vertica has been an on-premises database managing a data warehouse. But with the ease of cloud storage, Vertica Accelerator is looking to give you a data lake as a service. If you’re unfamiliar, data lakes take the data warehouse concept—central storage for all your data—and remove limits. You can have “rivers” of data flowing into your stores; if you go from a terabyte to a petabyte overnight, your cloud provider will handle it for you. Vertica has worked with plenty of industries that push massive amounts of data: healthcare, aviation, online games. They’ve built a lot of functionality into the database itself to speed up all manner of applications. One of their prospective customers had a machine learning model with thousands of lines of code that was reduced to about ten lines because so much was being done in the database itself. In the future, Vertica plans to offer more powerful management of data warehouses and lakes, including handling the metadata that comes with them.

Gen Z doesn’t understand file structures
It’s not news that, as Cassidy says, “remote has grown wildly fast”—but Remote has gone from about 25 employees in March 2020 to 900 now (a 3,500% increase).Ceora explains to Matt (oh, sweet summer’s child) what it means to get ratioed on Twitter.Inspired by a great read, the team discusses how Gen Z, having grown up without floppy disks, file folders, or directories, thinks about information.This week’s Lifeboat badge goes to user 1983 for their answer to the question Why can I not use `new` with an arrow function in JavaScript/ES6?.

China’s only female Apache member on the rise of open source in China
SphereEX builds distributed data systems, making it easier for organizations to load balance massive data stores across multiple servers. Now that open-source software has taken over Western software, it’s China’s turn. Even big companies like Baidu and Bytedance are opening up their projects. Trista is the only female Apache member in China, which is both an honor and a demonstration of how much work needs to be done to support women in STEM. This episode’s Lifeboat badge shoutout goes to swati kiran for her answer to Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/node-sass/build'.

A collaborative hub for infrastructure as code
On this sponsored episode of the podcast, we talk with Marcin Wyszynski, founder and CEO at Spacelift. Marcin says Spacelift aims to be for infrastructure-as-code what GitHub is to git. It centralizes everything about your IaC system: it runs code, deploys within CI/CD pipelines, tracks the progress of your infrastructure, and gives you insight into who made what changes and why. Today it works with the IaC tools already out there: Terraform, Cloud Formation, and Pulumi, with plans to add support for services like Ansible and Kubernetes in the future. Like a lot of programmers, Marcin got into coding through games. Once he ran through the limited number of Commodore 64 games at his local shop in Poland, he learned to program his own. But he never thought of programming as a career, so when it came time to pick a college major, he followed a group of his peers into sociology. Sociology, with its heavy focus on statistics, brought him back to programming. He landed his first job at Google reviewing copy for Ads, which lasted until he could automate himself out of it. Google gave him increasingly technical roles until he moved into an SRE position handling tape backups, a job that is mostly very boring until it becomes extremely exciting. After that, it was a stint at Facebook spinning up point-of-presence clusters around the world, then CTO at a startup that didn’t catch on as he’d hoped. With this wealth of experience under his belt, he went into consulting. As a consultant, he had his bag of best practices, open-source tools, processes, and scripts that he brought with him, but he also built bespoke pieces of technology for every single one of his clients. One need his clients had in common was a way to manage the code that defined their infrastructure. During Marcin’s career, there were many times when he built the thing he needed: games, automation, scripts. When his consulting clients would leave for a new organization, they would reach out to ask if he could provide them with the solution he had built for infrastructure as code. Realizing that he had created something which addressed a pain point common to many companies, he decided to turn this solution into a new company: Spacelift. Spacelift aims to take the heavy lifting out of infrastructure-as-code, automate it, and make it auditable. When a change gets made, everyone can see it and comment on it. From the product manager to the junior dev, everyone knows what’s going on, even if an infrastructure change doesn’t fit the original architecture docs. Plus, the SRE team no longer need to go on archeological expeditions to find a database secretly running and costing the company five figures a month. To learn more about Spacelift, check out their website at https://spacelift.io/, where you can start a free trial and see it in action.
