Feed: Planet MySQL; Author: MySQL Performance Blog; You got yourself a Kubernetes cluster and are now testing our Percona Kubernetes Operator for Percona XtraDB Cluster. Everything is working great and you decided that you want to increase the number of Percona XtraDB Cluster (PXC) pods from the default 3, to let’s say, 5 pods. It’s just a matter of running the following command: kubectl patch pxc cluster1 --type='json' -p='[{"op": "replace", "path": "/spec/pxc/size", "value": 5 }]'kubectl patch pxc cluster1 --type='json' -p='[{"op": "replace", "path": "/spec/pxc/size", "value": 5 }]'Good, you run the command without issues and now you will have 5 pxc pods! ...

Feed: SAS Blogs. Author: Chris Hemedinger. If your work environment is like ours here at SAS, you're seeing more of your data and applications move to the cloud. It's not yet a complete replacement for having local files on your desktop machine, but with cloud storage and apps -- like Microsoft OneDrive -- I can now access my work documents from any browser and any device, including my smartphone. I can update now my spreadsheets while waiting in the dentist office. Oh joy. For those of us who use SAS to read and create Microsoft Excel documents, cloud-based files can ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A smashing new RcppSimdJson release 0.1.0 containing several small updates to upstream simdjson (now at 0.4.6) in part triggered by very excisting work by Brendan who added actual parser from file and string—and together with Daniel upstream worked really hard to make Windows builds as well as complete upstream tests on our beloved (ahem) MinGW platform possible. So this version will, once the builders have caught up, give everybody on Windows a binary—with a JSON parser running circles around the (arguably more feature-rich and possibly easier-to-use) alternatives. Dave just tweeted a benchmark snippet ... Read More

Feed: Redis Labs. Author: Kyle Davis. I am personally guilty of describing streams in the wrong way—I’ve defined it as a “series of hashmap-like elements, ordered by time, under a single key.” This is incorrect. The last bit regarding time and key are OK, but the first bit is all wrong.  Let’s take a look at why streams are misunderstood and how they actually behave. We’ll evaluate the good and the bad of this misunderstanding and how it could affect your software. Finally, we’ll examine a few non-obvious patterns that take advantage of the little-known properties of Redis Streams.  Background ... Read More

Feed: AWS Compute Blog. Author: James Beswick. Many web applications experience high levels of traffic and spiky load patterns. The goal of load testing is to ensure that the architecture and system design works for the amount of traffic expected. It can help developers find bottlenecks and unexpected behavior before a system is deployed to production. This post uses the Ask Around Me application as an example to show how to test load in a serverless architecture.In Ask Around Me, users ask and answer questions in their local geographic area. The expected hourly load is 1,000 new questions, 10,000 new ... Read More

Feed: Teradata Blog. Over the past few years, the adoption of cloud object store services like AWS-S3 and Azure Blob has exploded largely because these services are simple to use, low maintenance, cost effective, and scale easily. If you are like most Teradata customers, you’ve also been experimenting with cloud object stores to determine how they can best fit into your enterprise IT ecosystem and support your business. Indeed, you may have even gone so far as to develop an entire corporate data lake strategy based on cloud object stores.Wherever you are on the cloud object store adoption curve, I’m ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; The Percona Kubernetes Operator for Percona XtraDB Cluster(PXC) comes with ProxySQL as part of the deal. And to be honest, the behavior of ProxySQL is pretty much the same as in a regular non-k8s deployment of it. So why bother to write a blog about it? Because what happens around ProxySQL in the context of the operator is actually interesting.ProxySQL is deployed on its own POD (that can be scaled as well as the PXC Pods can). Each ProxySQL Pod has its own ProxySQL Container and a sidecar container. If you are curious, ... Read More
