Apache Kafka® Schema Registry is now available on the Instaclustr Managed Platform
Instaclustr is pleased to announce the availability of Schema Registry support as an add-on for Kafka offering on the Instaclustr Managed Platform. When using Apache Kafka, there is an implicit assumption that developers of Kafka clients (Producers and Consumers) ensure the implementation takes care that the format of the messages being written to and read...

Announcing New Instance Type (i3s) and SSD Based Storage for Apache Kafka® on AWS
Since the launch of Instaclustr Managed Kafka, we have gained broad production experience managing Apache Kafka across a wide range of use cases. With more production clusters, we are learning more about Kafka and how best to tune and optimise it for performance, scale, and reliability. Part of the learning was that Kafka is being...

Anomalia Machina 10: Final Results with Apache Kafka® and Apache Cassandra®
In this tenth and final blog of the Anomalia Machina series we tune the anomaly detection system and succeed in scaling the application out from 3 to 48 Cassandra nodes, resulting in some impressive numbers: 574 CPU cores (across Cassandra, Kafka, and Kubernetes clusters), 2.3 million writes/s into Kafka (peak), 220,000 anomaly checks per second...

Anomalia Machina 9: Anomaly Detection at Scale
In the previous blog, we deployed the Anomalia Machina application in a production-like Kubernetes environment. In this blog, we test it out and see many anomalies it can detect at scale on small Kafka and Cassandra Instaclustr production clusters. Coming towards the end of our epic odyssey we now have a final challenge to overcome....

Speculative Query Executions with GoCql
What are speculative query executions? Speculative query executions in Cassandra are an interesting solution for some use cases, such as faulty/slow/unresponsive nodes or network issues. This kind of execution allows a client to launch a DB request for multiple endpoints at the same time and let these requests compete for the winning response. This would...

Anomalia Machina 8: Production Application Deployment With Kubernetes
In the previous blog we explored deploying the Anomalia Machina application on Kubernetes with the help of AWS EKS. In the recent blogs (Anomalia Machina 5 and Anomalia Machina 6), we enhanced the observability of the Anomalia Machina Application using two Open Source technologies: Prometheus for distributed monitoring of metrics such as throughput and latency;...

SLAs – Watch Out for the Shades of Gray
The Service Level Agreement (SLA) is an integral part of an MSP’s (Managed Service Provider) business. Its purpose is to define the scope of services that the MSP offers, including: guarantees on metrics relevant to their business and technology customer responsibilities issue management compensation commitment when MSPs fail to deliver on the SLA. It should...

Upgraded Compute Intensive Node Sizes for AWS Clusters
Last year, Instaclustr upgraded its support for high throughput, compute intensive nodes on top of the AWS platform. This involved switching away from the aging c3 instance types and onto the newer c5d instance type. The new c5d instances provide better performance, better compute power and is better value for money than the c3 instances....
