The JCache connector is mostly equivalent to the map connector, the main difference being that the JCache connector is compliant with the JCache standard API. As a sink, since JCache doesn’t support entry processors, only the default variant is available.
This connector is included in the full and slim distributions of Hazelcast.
If you use Hazelcast Enterprise, you can set up permissions to restrict clients' access to these data structures. For details, see Client Security.
