Peloton: Uber’s Unified Resource Scheduler for Diverse Cluster Workloads

By Min Cai & Mayank Bansal

Cluster management, a common software infrastructure among technology companies, aggregates compute resources from a collection of physical hosts into a shared resource pool, amplifying compute power and allowing for the flexible use of data …

The Future Of The Application Stack

Containers are eating the world. If you have built and deployed an application in production over the last few years, the odds are that you have deployed your code in containers. You might have created and deployed individual containers (Docker, Linux LXC, etc.) directly in the beginning, but quickly switched over to a container orchestration technology like Kubernetes (K8s) or Swarm when you needed to coordinate multi-node deployments and high availability (HA). In this container-driven world, what will the future of the application stack look like? Let’s start with what we need from this “future” application stack.

What Do We Need From This Future Application Stack?

This Week in Data With Colin Charles 51: Debates Emerging on the Relicensing of OSS

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

There has been a lot of talk around licenses in open source software, and it has hit the database world in the past weeks. Redis Labs relicensed some AGPL software to the Commons Clause (in their case, Apache + Commons Clause; so you can’t really call it Apache any longer). I’ll have more to say on this topic soon, but in the meantime you might enjoy reading Open-source licensing war: Commons Clause. This was the most balanced article I read about this move and the kerfuffle it has caused. We also saw this with Lerna (not database related), and here’s another good read: …

On Innovation. Interview with Scott McNealy

“We made it a point to hire really smart, visionary people and then let them do their work.
I wanted to delegate and let people be in charge of things. My own decision-making process was to decide who got to decide. To make decisions, you have to first outline the problem, and if you hire really great people, they’re going to know more about the problem they’re dealing with than you ever will.”–Scott McNealy

I have interviewed Scott McNealy. Scott is a Silicon Valley pioneer, most famous for co-founding Sun Microsystems in 1982. We talked about Innovation, AI, Big Data, Redis, Curriki and Wayin.

This Week in Data with Colin Charles 42: Security Focus on Redis and Docker a Timely Reminder to Stay Alert

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Much of last week, there was a lot of talk around this article: New research shows 75% of ‘open’ Redis servers infected. It turns out, it helps that one should always read beyond the headlines because they tend to be more sensationalist than you would expect. From the author of Redis, I highly recommend reading Clarifications on the Incapsula Redis security report, because it turns out that in this case, it is beyond the headline. The content is also suspect. Antirez had to write this to help the press (we totally need to help keep reportage accurate).

Not to depart from the Redis world just yet, but …

On RDBMS, NoSQL and NewSQL databases. Interview with John Ryan

“The single most important lesson I’ve learned is to keep it simple. I find designers sometimes deliver over-complex, generic solutions that could (in theory) do anything, but in reality are remarkably difficult to operate, and often misunderstood.”–John Ryan

I have interviewed John Ryan, Data Warehouse Solution Architect (Director) at UBS.

RVZ

Q1. You are an experienced Data Warehouse architect, designer and developer. What are the main lessons you have learned in your career?

John Ryan: The single most important lesson I’ve learned is to keep it simple. I find designers sometimes deliver over-complex, generic solutions that could (in theory) do anything, but in reality are remarkably difficult to operate, and often misunderstood. I believe this stems from a lack of understanding of the …

On Apache Ignite, Apache Spark and MySQL. Interview with Nikita Ivanov

“Spark and Ignite can complement each other very well. Ignite can provide shared storage for Spark so state can be passed from one Spark application or job to another. Ignite can also be used to provide distributed SQL with indexing that accelerates Spark SQL by up to 1,000x.”–Nikita Ivanov.

I have interviewed Nikita Ivanov,CTO of GridGain.
Main topics of the interview are Apache Ignite, Apache Spark and MySQL, and how well they perform on big data analytics.

RVZ

Q1. What are the main technical challenges of SaaS development projects?

Nikita Ivanov: SaaS requires that the applications be highly responsive, reliable and web-scale. SaaS development projects face many of the same challenges as …

A roughneck walk down database alley

via GIPHY I was just responding to some Disqus comments on a recent blog post. Admittedly it had a provocative title Will SQL databases just die already. What do you think? Join 34,000 others and follow Sean Hull on twitter @hullsean. A reader pointed out that some No-SQL databases do support joins. Huh? My face … Continue reading A roughneck walk down database alley →

What engineering roles are most in demand at startups?

via GIPHY I was just reading over StackOverflow’s 2017 Developer survey. As it turns out there were some surprising findings. Join 33,000 others and follow Sean Hull on twitter @hullsean. One that stood out was databases. In the media, one hears more and more about NoSQL databases like Cassandra, Dynamo & Firebase. Despite all that … Continue reading What engineering roles are most in demand at startups? →

JSON Support in PostgreSQL, MySQL, MongoDB, and SQL Server

Updated 2/10/2017

If you've been watching the evolution of database technologies over the past few years, you've seen how quickly JSON has quickly cemented its position in major database servers. Due to its use in the web front-end, JSON has overtaken XML in APIs, and it’s spread through all the layers in the stack one step at a time.

Most major databases supported XML in some fashion for a while, too, but developer uptake wasn’t universal. JSON adoption among developers is nearly universal today, however. (The king is dead, long live the king!) But how good is JSON support in the databases we know and love? We’ll do a comparison in this blog post.
