Feed: Planet PostgreSQL. Debezium is a popular Open Source change data capture (CDC) solution. It’s based on a set of well-established components (Kafka, Kafka Connect, ZooKeeper) and used successfully in production by companies like Dehlivery or BlaBlaCar. However, the setup is not as straightforward as one may think, and you may encounter some obstacles. In this post, I will share some tips originating from hooking up Debezium to a quite big and busy OLTP Postgres database. Originally, Debezium was connected to a Postgres DB using a wal2json or decoderbufs plugins. Don’t use them – as native logical replication became available ... Read More

Feed: AWS Big Data Blog. Many organizations are processing and analyzing clickstream data in real time from customer-facing applications to look for new business opportunities and identify security incidents in real time. A common practice is to consolidate and enrich logs from applications and servers in real time to proactively identify and resolve failure scenarios and significantly reduce application downtime. Internet of things (IOT) is also driving more adoption for real-time data processing. For example, a connected factory, connected cars, and smart spaces enable seamless sharing of information between people, machines, and sensors. To help ingest real-time data or streaming ...

Feed: AWS Compute Blog. Author: Benjamin Smith. Today, AWS is introducing Synchronous Express Workflows for AWS Step Functions. This is a new way to run Express Workflows to orchestrate AWS services at high-throughput. Developers have been using asynchronous Express Workflows since December 2019 for workloads that require higher event rates and shorter durations. Customers were looking for ways to receive an immediate response from their Express Workflows without having to write additional code or introduce additional services. What’s new? Synchronous Express Workflows allow developers to quickly receive the workflow response without needing to poll additional services or build a custom ... Read More

Feed: Planet MySQL; Author: Vitess; IntroductionIn this blog, I would like to explore Vitess Operator for Kubernetes. This post demonstrates the sample implementation of Vitess in Kubernetes topology. I also explore common DBA tasks by demonstrating how they are handled in the Vitess ecosystem. Vitess, out of the box, comes with a lot of tools and utilities that one has to either incorporate or develop to manage MySQL topology. Let’s take a look at the capabilities of Vitess in these areas and demonstrate how they are performed under the operator realm.PrerequisitesGKE AccountKubectlMySQL ClientInstall vtctlclient locallygo get vitess.io/vitess/go/cmd/vtctlclientDownload the Operator example ...

Feed: Planet PostgreSQL. At most of the places I've worked, the primary language used was not what I gravitated to naturally. If you're going to ask for a language of choice personally, it's python. I appreciate the explicit nature, that it's often pseudocode that can execute and it has a rich ecosystem of libraries (though that’s most languages these days). But as much as anything I latched onto Django in its early days. If you're not familiar with Django it's a popular framework for web apps written in Python. What I loved about it in particular was one of its ... Read More
