Combining Transactional And Analytical Workloads On MemSQL with Nikita Shamgunov
56:55 Share

SummaryOne of the most complex aspects of managing data for analytical workloads is moving it from a transactional database into the data warehouse. What if you didn’t have to do that at all? MemSQL is a distributed database built to support concurrent use by transactional, application oriented, and analytical, high volume, workloads on the same hardware. In this episode the CEO of MemSQL describes how the company and database got started, how it is architected for scale and speed, and how it is being used in production. This was a deep dive on how to build a successful company around a powerful platform, and how that platform simplifies operations for enterprise grade data management.Preamble

• Hello and welcome to the Data Engineering Podcast, the show about modern data management
• When you’re ready to build your next pipeline you’ll need somewhere to deploy it, so check out Linode. With private networking, shared block storage, node balancers, and a 40Gbit network, all controlled by a brand new API you’ve got everything you need to run a bullet-proof data platform. Go to dataengineeringpodcast.com/linode) to get a $20 credit and launch a new server in under a minute.
• You work hard to make sure that your data is reliable and accurate, but can you say the same about the deployment of your machine learning models? The Skafos platform from Metis Machine was built to give your data scientists the end-to-end support that they need throughout the machine learning lifecycle. Skafos maximizes interoperability with your existing tools and platforms, and offers real-time insights and the ability to be up and running with cloud-based production scale infrastructure instantaneously. Request a demo at dataengineeringpodcast.com/metis-machine) to learn more about how Metis Machine is operationalizing data science.
• And the team at Metis Machine has shipped a proof-of-concept integration between the Skafos machine learning platform and the Tableau business intelligence tool, meaning that your BI team can now run the machine learning models custom built by your data science team. If you think that sounds awesome (and it is) then join the free webinar with Metis Machine on October 11th at 2 PM ET (11 AM PT). Metis Machine will walk through the architecture of the extension, demonstrate its capabilities in real time, and illustrate the use case for empowering your BI team to modify and run machine learning models directly from Tableau.

• Your host is Tobias Macey and today I’m interviewing Nikita Shamgunov about MemSQL, a newSQL database built for simultaneous transactional and analytic workloads

Interview

• Introduction

• How did you get involved in the area of data management?

• Can you start by describing what MemSQL is and how the product and business first got started?

• What are the typical use cases for customers running MemSQL?

• What are the benefits of integrating the ingestion pipeline with the database engine? 

• What are some typical ways that the ingest capability is leveraged by customers?

• How is MemSQL architected and how has the internal design evolved from when you first started working on it?
