snowcast - like christmas in the distributed Hazelcast world

snowcast is an auto-configuration, distributed, scalable ID generator on top of Hazelcast

snowcast is an auto-configuration, distributed, scalable ID generator on top of Hazelcast. Since snowcast is not an official Hazelcast project, Hazelcast will not offer any kind of commercial support for it, it is one of my private spare time projects!

Why this project?

While working on a side project I came across the need for a scalable ID generator. A couple of possible solutions were available but non of those as fast as possible but I found a few interesting ideas, one of them will be shown in this blogpost. As mentioned above, this is just my private project. I give support on best effort and I love to help and share the code. All source code is available under Apache License 2, same as almost all of my open source projects
