C++ Client

API docs
6.0-SNAPSHOT 5.5 5.4 5.3 5.2 5.1 5.0
For the latest C++ API documentation, see Hazelcast C++ Client docs.

You can use the native C++ client to connect to Hazelcast cluster members and perform almost all operations that a member can perform. Clients differ from members in that clients do not hold data. The C++ client is by default a smart client, i.e., it knows where the data is and asks directly for the correct member. You can disable this feature (using the client_config::set_smart_routing method) if you do not want the clients to connect to every member.

The features of C++ clients are listed below:

  • Access to distributed data structures (imap, iqueue, multi_map, etc.).

  • Access to transactional distributed data structures (transactional_map, transactional_queue, etc.).

  • Ability to add cluster listeners to a cluster and entry/item listeners to distributed data structures.

  • Distributed synchronization mechanisms with fenced_lock, counting_semaphore and latch.

See Hazelcast C++ client’s own GitHub repo for information on setting the client up, installing and compiling it, its serialization, query support and available APIs. You can also find code samples for this client in this repo.
