We are pleased to welcome Abuli Palagashvili, who was selected to participate in Google Summer of Code (GSoC) on Apache Cassandra this year. He will be working primarily on CASSANDRA-16451.

As the project looks to the future, we are adding a roadmap page to the new /[Apache Cassandra project website,window=_blank]. The community is also looking towards new features, and you can take a look at the features that developers plan to work on here.

If you weren’t able to make the Cassandra World Party, we have uploaded a playlist of all the recorded lightning talks, which include such gems as Making Cassandra Easy, Raising the Bar on Q&A, which covers all the testing and CI we do on the project, and why Target chose Cassandra and the key takeaways from that move.

We anticipate announcing ARM platform support for the release of 4.0 GA and are looking into how to create ARM-specific releases in a way that enables the project to store GPG private keys that complies with ASF Release Distribution Policy.

Huawei Cloud has provided six arm64 servers, which have been instrumental in getting the build and tests running on arm64. This is a huge contribution to the community and the PMC would like to say a big and public "thank you" for the initiative from all of us.

On May 11, Grafana released Apache Cassandra Datasource for Grafana for visualizing time-series data.

When Grubhub and Seamless merged, the company set out to build a new platform. One of those important decisions was deciding to use Apache Cassandra as the primary persistent data store for Grubhub’s backend services: “Our goal was to build a highly scalable, highly available system that could scale to meet traffic, handle various network and infrastructure outages as well as our growing business needs.” - William Blackie

Home Depot has been on an accelerated digital transformation through the pandemic, moving to an architecture that connects logistics, delivery, supply chain, customers, digital channels, and associates. One key effort involved using Apache Cassandra to stand up curb side apps quickly. “Some of the tenants of that One Home Depot journey has been creating a set of common services, a common API, a common compute environment. There will be shared decisions between all our different channels. As we’ve developed these common services, we have been able to really reconcile what a customer sees online, what an associate gets to see in store, and how to connect it all together.” - Fahim Siddiqui
