Pros
The community but it's declining
Cons
1- Abandoning Open Source: Key features like the CP Subsystem are now locked behind Enterprise Edition, alienating developers. 2- Lack of Innovation: Minimal progress, with features stuck in beta and old tech repackaged instead of improved. 3- Leadership Instability: Frequent leadership changes prioritize short-term sales over innovation. 4- Market Decline: With weak OSS support and stagnant development, Hazelcast is losing relevance. 5- Low Morale: Engineers feel disengaged due to the lack of open-source involvement and product stagnation. 6- Version Transparency Issues: Hazelcast quietly replaced version 5.5.3 with 5.5.4, raising concerns about stability and communication. Final Verdict: Hazelcast has moved away from open-source and innovation, prioritizing paywalled features. If you need cutting-edge, community-driven technology, look elsewhere.
