Summary Transactional databases used in applications are optimized for fast reads and writes with relatively simple queries on a small number of records. Data warehouses are optimized for batched writes and complex analytical queries. Between those use cases there are varying levels of support for fast reads on quickly changing data. To address that need more completely the team at Materialize has created an engine that allows for building queryable views of your data as it is continually updated from the stream of changes being generated by your applications. In this episode Frank McSherry, chief scientist of Materialize, explains why it was created, what use cases it enables, and how it works to provide fast queries on continually updated data.

Summary Building clean datasets with reliable and reproducible ingestion pipelines is completely useless if it’s not possible to find them and understand their provenance. The solution to discoverability and tracking of data lineage is to incorporate a metadata repository into your data platform. The metadata repository serves as a data catalog and a means of reporting on the health and status of your datasets when it is properly integrated into the rest of your tools. At WeWork they needed a system that would provide visibility into their Airflow pipelines and the outputs produced. In this episode Julien Le Dem and Willy Lulciuc explain how they built Marquez to serve that need, how it is architected, and how it compares to other options that you might be considering. Even if you already have a metadata repository this is worth a listen to learn more about the value that visibility of your data can bring to your organization.

Business decisions today are tactical and strategic at the same time. How do you respond to a competitor’s price change? Or to specific technology changes? What new products, markets, or businesses should you pursue? Decisions like these are based on information from only one source: data. With this practical report, technical and non-technical leaders alike will explore the fundamental elements necessary to embark on a data analytics initiative. Is your company planning or contemplating a data analytics initiative? Authors Brett Stupakevich, David Sweenor, and Shane Swiderek from TIBCO guide you through several analytics options. IT leaders, product developers, analytics leaders, data analysts, data scientists, and business professionals will learn how to deploy analytic components in streaming and embedded systems using one of five platforms. You’ll examine: Analytics platforms including embedded BI, reporting, data exploration & discovery, streaming BI, and data science & machine learning The business problems each option solves and the capabilities and requirements of each How to identify the right analytics type for your particular use case Key considerations and the level of investment for each analytics platform

Summary With the constant evolution of technology for data management it can seem impossible to make an informed decision about whether to build a data warehouse, or a data lake, or just leave your data wherever it currently rests. What’s worse is that any time you have to migrate to a new architecture, all of your analytical code has to change too. Thankfully it’s possible to add an abstraction layer to eliminate the churn in your client code, allowing you to evolve your data platform without disrupting your downstream data users. In this episode AtScale co-founder and CTO Matthew Baird describes how the data virtualization and data engineering automation capabilities that are built into the platform free up your engineers to focus on your business needs without having to waste cycles on premature optimization. This was a great conversation about the power of abstractions and appreciating the value of increasing the efficiency of your data team.

Summary The practice of data management is one that requires technical acumen, but there are also many policy and regulatory issues that inform and influence the design of our systems. With the introduction of legal frameworks such as the EU GDPR and California’s CCPA it is necessary to consider how to implement data protectino and data privacy principles in the technical and policy controls that govern our data platforms. In this episode Karen Heaton and Mark Sherwood-Edwards share their experience and expertise in helping organizations achieve compliance. Even if you aren’t subject to specific rules regarding data protection it is definitely worth listening to get an overview of what you should be thinking about while building and running data pipelines.

Summary As data engineers the health of our pipelines is our highest priority. Unfortunately, there are countless ways that our dataflows can break or degrade that have nothing to do with the business logic or data transformations that we write and maintain. Sean Knapp founded Ascend to address the operational challenges of running a production grade and scalable Spark infrastructure, allowing data engineers to focus on the problems that power their business. In this episode he explains the technical implementation of the Ascend platform, the challenges that he has faced in the process, and how you can use it to simplify your dataflow automation. This is a great conversation to get an understanding of all of the incidental engineering that is necessary to make your data reliable.

We’d love to hear from you.Just a heads up that we’ll be switching formats from two times a week to two to three times a month as we transition to a longer form podcast that will include interviews with some very special guests.DateWithout further ado, this is your Data Dump for Friday, Nov. 1, 2019.My Chemical Romance’s Reunion Shows Scary Good NumbersHope you had a very spooky and safe Halloween.There’s no trick here: For early 2000s pop-punk nostalgists and emo aficionados, My Chemical Romance dropped a very special treat.The eye shadow-laden foursome announced their reunion on the most costume-heavy day of the year, and the internet was all about it.If you were sitting there thinking the emo/pop-punk thing was just a fad, think again, because MCR’s numbers show otherwise. Sure, it’s been six years since their break-up, but their numbers have been steadily climbing since we started tracking their data.In March 2018, the band was at 4.9M Spotify Monthly Listeners, 2.7M Followers, and a Spotify Popularity Index of 78 out of 100.As of Halloween, they’re at 6.7M Spotify Monthly Listeners, 4.3M Followers, and a Spotify Popularity Index of … drum roll please: 78!Those stats are pretty stunning — six years of effective inactivity, and MCR has managed to maintain their streaming numbers.If we look at their Neighboring Artists and filter by genre cluster, things get more impressive. Paramore, who are just above them in terms of Cross-Platform Performance rank, are at the same Spotify popularity level.However, Paramore released an album just two and a half years ago, and they were releasing new music videos as recently as last year.To be fair, MCR has had help from frontman Gerard Way’s award-winning comic books — one of which has a Netflix adaptation — in addition to his and other members’ side projects and the band’s 2016 reissue of 2006’s The Black Parade.However, with a band that hasn’t really had a frontline release for six years and is still maintaining their metrics, a Halloween announcement of their December reunion can only mean one thing right?There’s nowhere to go but up.Already, we see a daily Spotify Monthly Listener change from -891 to 7.4K, a daily Twitter Follower gain from 51 to 46K, a daily Instagram Follower gain from 140 to 12.7K, and a daily YouTube Channel Views gain from about half a million to just under a million.Now, that’s scary good, so bravo, My Chemical Romance, bravo.OutroThat’s it for your Daily Data Dump for Friday, Nov. 1, 2019.

Summary Despite the fact that businesses have relied on useful and accurate data to succeed for decades now, the state of the art for obtaining and maintaining that information still leaves much to be desired. In an effort to create a better abstraction for building data applications Nick Schrock created Dagster. In this episode he explains his motivation for creating a product for data management, how the programming model simplifies the work of building testable and maintainable pipelines, and his vision for the future of data programming. If you are building dataflows then Dagster is definitely worth exploring.

Interview

Introduction How did you get involved in the area of data management? Can you start by explaining what Dagster is and the origin story for the project? In the tagline for Dagster you describe it as "a system for building modern data applications". There are a lot of contending terms that one might use in this context, such as ETL, data pipelines, etc. Can you describe your thinking as to what the term "data application" means, and the types of use cases that Dagster is well suited for? Can you talk through how Dagster is architected and some of the ways that it has evolved since you first began working on it?

What do you see as the current industry trends that are leading us away from full stack frameworks such as Airflow and Oozie for ETL and into an abstracted programming environment that is composable with different execution contexts? What are some of the initial assumptions that yo

Highlights  This week, two huge artists let the track lists of their upcoming albums slip and a couple of other big names released music videos. Let’s see if they reaped any data rewards. Mission   Good morning, it’s Rutger here at Chartmetric with your 3-minute Data Dump where we upload charts, artists, and playlists into your brain so you can stay up on the latest in the music data world.We’re on the socials at “chartmetric” — that’s Chartmetric, one word and no “S.” Follow us on LinkedIn, Instagram, Twitter, or Facebook, and talk to us! We’d love to hear from you.DateThis is your Data Dump for Friday, Oct. 25, 2019.Track List Reveals and Music Videos: Stunts or Bumps?Coldplay and Miley Cyrus let the track listings for their respective upcoming albums drop this week, while Doja Cat and Selena Gomez released some music video eye candy to promote their upcoming album releases.We’re not saying the strategies are mutually exclusive by any means, but what are the actual gains from each, from a data perspective?Coldplay, who cheekily revealed the track list of their upcoming album by posting a classified ad in North Wales’ Daily Post, have been pretty good about staying in the spotlight, but amidst collabs and side projects, they’ve still managed to put together a double album called “Everyday Life,” which is due out Nov. 22.So far, the sneaky announcement has garnered tons of press, helped along by the release of “Arabesque” and “Orphans,” two tracks from each album.It probably didn’t cost them very much, either.While the effect seems relatively negligible now due its two-day freshness, across most platforms, they’re showing signs of an upward trajectory.They’ve gained some 30K Spotify followers, 5K Insta followers, 2K Twitter followers, and 8.5K Wikipedia views. They’ve also increased their Spotify popularity by a point, which is not insignificant in just a day or two’s work.Clearly, Coldplay had a lot of intention behind their track list leak, but Miley Cyrus’ situation is a bit murkier.During a livestream on Instagram on Sunday, viewers spotted a whiteboard behind Miley with a bunch of, well, presumably track names scrawled all over it.It doesn’t look staged, but then again, her upcoming album isn’t exactly a secret, so there could be a bit of guerilla marketing going on there.Seeing as she hasn’t released anything “tangible” this week, her metrics are a bit more stagnant, which is not to diminish her No. 10 rank across eight platforms, according to our Cross-Platform Performance ranking system.Two artists who have some audiovisual tangibility to show are former Disney star Selena Gomez and LA-based rapper Doja Cat.Gomez’s “Look at Her Now” music video has bumped her up in terms of fan acquisition on Spotify, Instagram, Twitter, SoundCloud, and YouTube, but her streams and views aren’t seeing a huge lift … yet.She did just release two new singles within a day of each other, so those follower gains are likely to bump up her listener and views gains in the coming days.Star-on-the-rise Doja Cat was trending hard on Twitter following her music video/single drop of “Rules” and her streaming numbers are climbing and climbing.Just six months ago, Doja was at 1.9M Spotify Monthly Listeners.That number started accelerating in August, from 2.6M to 3.7M, and just this month, she’s gone from 4.6M to nearly 6M. Combined with her half-a-million-Spotify-followers-and-climbing, her Spotify popularity score is edging near the upper echelons of the streaming world.With the kind of attention that Doja’s powerfully provocative video is getting, there’s some definite streaming staying power there.So, while album track list leaks don’t appear to be particularly indicative of a data bump on their own, combined with a double-single release — especially if you’re Coldplay — they can be a relatively inexpensive strategy for generating a lot of attention.There’s nothing like a really cool music video to train and sustain all eyes on an artist, though.OutroThat’s it for your Daily Data Dump for Friday, Oct. 25, 2019.

Summary The scale and complexity of the systems that we build to satisfy business requirements is increasing as the available tools become more sophisticated. In order to bridge the gap between legacy infrastructure and evolving use cases it is necessary to create a unifying set of components. In this episode Dipti Borkar explains how the emerging category of data orchestration tools fills this need, some of the existing projects that fit in this space, and some of the ways that they can work together to simplify projects such as cloud migration and hybrid cloud environments. It is always useful to get a broad view of new trends in the industry and this was a helpful perspective on the need to provide mechanisms to decouple physical storage from computing capacity.

HighlightsPeloton’s recent IPO has us wondering about the most popular fitness playlists on Spotify and Deezer, so slap on some cross-trainers and fire up those Bluetooth earbuds.Mission   Good morning, it’s Jason here at Chartmetric with your 3-minute Data Dump where we upload charts, artists, and playlists into your brain so you can stay up on the latest in the music data world.We’re on the socials at “chartmetric” — that’s Chartmetric, one word and no “S.” Check us out on LinkedIn, Instagram, Twitter, and Facebook!DateThis is your Data Dump for Wednesday, Oct. 16, 2019.Music + Fitness: Shaping Up Spotify and Deezer’s Top Workout PlaylistsPeloton, the indoor fitness brand best associated with its high-energy, online-class guided cycling experiences, went public on Oct. 7th, but closed its first day 11% under its initial public offering price, according to CNN.Competitor SoulCycle pulled out of IPO-ing last year, and maybe it has something to do with the music issues Peloton is now facing: a $300M lawsuit from a group of music publishers.Whether they’re using IP legitimately or not, there’s a lot at stake when it comes to music’s intimate relationship to fitness, according to music/tech journalist Cherie Hu’s latest newsletter.And it’s definitely illustrated by Spotify’s most popular workout playlists, six of which are in the Top 100 in terms of Follower count:Beast Mode is the most popular context-based fitness playlist on the Swedish platform, and the 9th most followed overall at 6.5M Followers.Post Malone is currently getting the most unique monthly listeners from four playlist slots he’s currently sitting in, acquiring 891K MLs.Reggaeton king J Balvin and American DJ/producer Marshmello are in the #2 and #3 slots with 592K and 577K Beast Mode-specific MLs respectively.Almost 20% of the current list is tagged as EDM, and more than 30% if you include Brostep.More than half of the current list are American artists, with the second most-represented country being high-energy Dutch electronic artists like Armin van Buuren, Hardwell and R3HAB...but still comprising only 13% of the list.Spotify’s Motivation Mix at 4.4M Followers and the simply-titled Workout playlist at 3.3M are the next most popular fitness lists there, but an interesting juxtaposition may be Deezer’s most popular fitness playlist, Rock Workout.That’s right: the #1 list to work out to on the French streaming platform is based around the rock genre, which is very different from Spotify’s top workout mixes, which are usually hip-hop, pop or dance-based.Rock Workout has 342K fans and currently a 70-track count, compared to Beast Mode’s 200 track count.Up until mid-May this year, Beast Mode only held 50 tracks at once, and though the amount of slots open up in the playlist, they do a great job of keeping things fresh, with a 100% 28-day ratio, meaning that the entire list has changed in the past month.With Rock Workout, only 3% of the list has changed in the past month, even though it’s less than ¼ of Beast Mode’s track count, featuring artists such as Linkin Park, Nickelback and AC/DC.Other Deezer workout playlists like Rap & Sport and Motivation Hits at 324K fans each feature much of the same pop/hip-hop/EDM fare you may expect...but it just goes to show that not all sweat beads to the same drummer.Outro That’s it for your Daily Data Dump for Wednesday, Oct. 16, 2019.

Highlights  UK singer-songwriter and producer prodigy Labrinth has created a hallucinatory experience with his soundtrack of HBO’s new show Euphoria, and with data as our guide, we’re going to try to navigate the psychedelic experience with you.Mission   Good morning, it’s Rutger here at Chartmetric with your 3-minute Data Dump where we upload charts, artists, and playlists into your brain so you can stay up on the latest in the music data world.We’re on the socials at “chartmetric” — that’s Chartmetric, one word and no “S.” Follow us on LinkedIn, Instagram, Twitter, or Facebook, and talk to us! We’d love to hear from you.DateThis is your Data Dump for Friday, Oct. 11, 2019.Take a Psych Trip Through Labrinth’s ‘Euphoria’Besides collaborating with Sia, Diplo, and Beyonce in recent years, Timothy Lee McKenzie, better known by his stage name, Labrinth, just scored — literally and figuratively — his first TV series, HBO’s Euphoria.According to Rolling Stone, “His soundtrack ... hums with soft electricity, perfectly complementing the journey of the main character, Rue, a teenager caught in limbo between the euphoria of a drug high and the harsh consequences of addiction.”It’s rare that a TV show soundtrack generates high — if any at all — demand, but according to McKenzie himself, “If I put a post up, the first message is ‘Where’s the album? Where’s the soundtrack?!’ So I’m like, ‘OK, don’t worry.’ We’re working on getting ‘em what they need.”And he and the HBO team did just that, releasing the soundtrack last Friday.Though his early April releases of “SIN” and LSD, his Sia/Diplo collab, accounted for his highest Spotify Follower gains this year, at 5K and 3K, respectively, Euphoria has him at a 2K increase.That said, on Insta and Wikipedia, an early single drop from the soundtrack on Aug. 3 gave Labrinth his most significant spikes with a 5K follower increase and 3.5K views, respectively.It’s an interesting strategy for artists, labels, and managers to think about, because not only are there upfront fiscal upsides from synchronizations, but there are also the inherent promotional upsides couched in the television and video streaming industry’s massive marketing budgets. That’s not to say that it limits a series to only one artist, of course.Euphoria’s official Spotify playlist, which includes every track used in Season 1, ranges from Solange to Lizzo, Blood Orange to Randy Newman and much, much more.Unfortunately, an individual curator seems to have ripped the official Euphoria playlist and pawned it off as their own, outperforming the official playlist by about 3 to 1 in terms of follower count.Which just goes to show — albeit unscrupulously — that understanding and anticipating trends and listener behavior can go a long way toward building audiences in the streaming era.  OutroThat’s it for your Daily Data Dump for Friday, Oct. 11, 2019.

Summary The process of exposing your data through a SQL interface has many possible pathways, each with their own complications and tradeoffs. One of the recent options is Rockset, a serverless platform for fast SQL analytics on semi-structured and structured data. In this episode CEO Venkat Venkataramani and SVP of Product Shruti Bhat explain the origins of Rockset, how it is architected to allow for fast and flexible SQL analytics on your data, and how their serverless platform can save you the time and effort of implementing portions of your own infrastructure.

Interview

Introduction How did you get involved in the area of data management? Can you start by describing what Rockset is and your motivation for creating it?

What are some of the use cases that it enables which would otherwise be impractical or intractable?

How does Rockset fit into the infrastructure and workflow of data teams and what portions of a typical stack does it replace? Can you describe how the Rockset platform is architected and how it has evolved as you onboard more customers? Can you describe the flow of a piece of data as it traverses the full lifecycle in Rockset? How is your storage backend implemented to allow for speed and flexibility in the query layer?

How does it manage distribution, balancing, and durability of the data? What are your strategies for handling node and region failure in the cloud?

Highlights  Rolling Stone, Music Ally, and others were particularly interested in a surprising data point from Part 2 of 6MO, our first-ever Global Music Industry Data Report. What’s that all about?

We’d love to hear from you.DateThis is your Data Dump for Friday, Oct. 4, 2019.6MO Global Music Industry Data Report, Part 2: Platform-Playlist AnalysisThe domination by North American artists of the top streaming playlists was of particular interest to many major music publications as soon as we dropped 6MO.Obviously, it was to us too, but there was another trend that intrigued us in the Platform-Playlist Analysis section, or Part 2, of our Global Music Industry Data Report.That trend? The Top 5 genre differentiators on Amazon Music, Apple Music, Deezer, and Spotify’s Top 30 playlists.What exactly do we mean by genre differentiators and how did we get there?Well, we pulled geographic and genre metadata tags for every artist included on each of those 120 playlists, filtering out personalized and artist-specific ones, and then, we calculated the distribution for each platform set. What we found is that virtually across the board, Pop and Hip-Hop & Rap take the Top 2 spots in terms of artist genre distribution for all four of those streaming platforms on June 30, 2019.Generally speaking, those genres account for about half of the market share on those top playlists for those platforms.Where things get interesting is in the No. 3, No. 4, and No. 5 spots, because that’s where the platforms begin to diverge from one another. This is what we mean by genre differentiators in the Top 5 for each platform.On Amazon Music, for instance, Country makes the Top 5, which is not the case for any other platform. On Apple Music, R&B/Soul fills that role, on Deezer, it’s Latin & Carribean, and on Spotify, it’s Folk, Traditional, and World.Surprising? Maybe not, if you’ve had that hunch all along.It is both satisfying and also illuminating to see it borne out in the data, however — and that’s what we’re all about. If you want to see where Indie or any geographic region outside of North America stacks up, dig in to 6MO more here.OutroThat’s it for your Daily Data Dump for Friday, Oct. 4, 2019.
