Hazelcast

Hazelcast is a real-time data platform that helps businesses accelerate their applications with data caching, data integration, and distributed computing. Hazelcast provides in-memory computing capabilities for high-performance, low-latency applications, exposing a REST API for managing maps, queues, cluster state, configuration, and health.

Hazelcast publishes 5 APIs on the APIs.io network, including Cluster API, Configuration API, Health API, and 2 more. Tagged areas include Data Caching, Distributed Computing, In-Memory Computing, Real-Time, and REST.

Hazelcast’s developer surface includes documentation, getting-started guide, support, engineering blog, and 7 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hazelcast: open an issue to ask a question, or submit a pull request to add artifacts.
