+== Compare editions

+The open source module `io.vertx:vertx-hazelcast` is based on an AP data structure, IMap. If you require consistency over availability, you will need to use the `com.hazelcast:vertx-hazelcast-enterprise` module, which is based on CP data structures in the xref:cp-subsystem:cp-subsystem.adoc[CP Subsystem]. This requires an {enterprise-product-name} license.

+TIP: You can request a trial license from link:https://hazelcast.com/get-started/[].

+NOTE: SharedMap is implemented with IMap in both modules. Using CPMap would impact license costs and performance. You can still use CPMap directly using the Hazelcast API (not via Vert.x SharedData wrappers) if you have an {enterprise-product-name} license.
