Feed: Planet PostgreSQL. A customer recently asked if our Percona Distribution for PostgreSQL Operator supports the deployment of a standby cluster, which they need as part of their Disaster Recovery (DR) strategy. The answer is yes – as long as you are making use of an object storage system for backups, such as AWS S3 or GCP Cloud Storage buckets, that can be accessed by the standby cluster. In a nutshell, it works like this: The primary cluster is configured with pgBackRest to take backups and store them alongside archived WAL files in a remote repository; The standby cluster is ...

Feed: SAS Blogs. Author: Rick Wicklin. Recall that the binomial distribution is the distribution of the number of successes in a set of independent Bernoulli trials, each having the same probability of success. Most introductory statistics textbooks discuss the approximation of the binomial distribution by the normal distribution. The graph to the right shows that the normal density (the red curve, N(μ=9500, σ=21.79)) can be a very good approximation to the binomial density (blue bars, Binom(p=0.95, nTrials=10000)). However, because the binomial density is discrete, the binomial density is defined only for positive integers, whereas the normal density ... Read More

Feed: R-bloggers. Author: Franklin Parker. Summary Bitcoin is a hot topic at the moment, and understandably so. Few other assets have the potential to move 10% to 20% in a day. It is that volatility which as attracted so many investors (and that capital inflow has likely fueled subsequent gains). But, that level of volatility also belies our intuition about the return behavior of financial assets. In this analysis, I want to look at the return distribution which best describes Bitcoin. Better understanding the return distribution can help us to update our intuitions on the asset’s movements, and the role ... Read More

Feed: Planet MySQL; Author: Marco Tusa; I decided to write this article after a discussion with other colleagues.  We were wondering how and if the Percona Distribution for MySQL Operator(PDMO) could help a starting business or a new project inside an enterprise.  We were also wondering how it behaves in relation to already well established solutions, like Amazon RDS or Google SQL.  In fact, we often see analysis and benchmarking covering huge datasets and instances with very high levels of resources . But we tend to forget that any application or solution started as something small, and it is important ... Read More
