Redis Cluster is the native sharding implementation available within Redis that allows you to automatically distribute your data across multiple nodes without having to rely on external tools and utilities. At ScaleGrid, we recently added support for Redis Clusters on our platform through our fully managed Redis hosting plans. In this post, we’re going to introduce you to the advanced Redis Cluster sharding opportunities, discuss its advantages and limitations, when you should deploy, and

In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant. I reported that it can be fruitful to compute the remainder directly, instead of first computing the quotient (as compilers are doing when the divisor is a constant).

How browsers schedule and execute scripts can impact the performance of web pages. While techniques like , (and others) influence script loading, knowing how browsers interpret them can also be helpful. Thanks to Kouhei Ueno , we now have an up to date summary of script scheduling in Chrome.

instant.page is a pretty cool project from Alexandre Dieulot. Alexandre has been at this idea for half a decade now, as InstantClick is his and is essentially the same exact idea. The idea is that there is a significant delay between hovering over a link and clicking that link. Say it takes you 300ms of delay. That 300ms could have been spent preloading the next page.

Over the last decade, QA has moved from the periphery to become a priority for every business that produces software and apps. This focus has sparked much debate about whether development and testing should shift left or right. But both of these approaches fail to take into account how a customer uses the product. It's time for a new shift.

Years ago I was recruiting a replacement for myself in a leadership position, and I interviewed a Canadian man. I remember being impressed with the candidate’s thoughtfulness and people skills. After a while I asked him, “what is something you’ve learned from leadership?” His response was, “I’ve learned that treating people fairly is different from treating them equally.

To continue on my trend of MongoDB with Node.js material, I thought it would be a good idea to use one of my favorite Node.js frameworks. Previously I had written about using Express.js with Mongoose , but this time I wanted to evaluate the same tasks using Hapi.js. In this tutorial we’re going to develop a simple RESTful API using Hapi.js , Joi and Mongoose as the backend framework, and MongoDB as the NoSQL database.

Failing fast has become a common trope by now. It makes a lot of sense in some contexts. Fear of failing causes many problems, the biggest of which is being afraid to try something new. Even if a new thing only has a 1% chance of teaching you something useful, not trying gives you a 0% chance of learning something useful. Fear of failing prevents long term success.

Compressability. What space savings should you expect when running databases with default compression in a Nutanix cluster? When we ran the TPCx-HCI benchmark on our cluster we realized about 2:1 savings from compression alone. The TPCx-HCI benchmark mimics a database consolidation setup, meaning that there are many databases per host. The uncompressed data size was about 45TB.
