Getting Started with a Hazelcast Client
Hazelcast has clients in Java, .NET, Python, C++, Go, Node.js and Memcache. You can use these clients to communicate with cluster members.
For documentation and code samples for each client, see the following:
You can also check out the REST API for simple operations:
Additional tools are available to help operate and manage Hazelcast Platform clusters: * Management Center * Platform Operator * Command Line Client (CLC)
Feature Comparison for Hazelcast Clients
Not all features are available in all clients.
To find out which features are available in each client, see the clients page.
After selecting the language you need, you can find the table showing supported features on the selected language.
Maximum Number of Client Connections Per Member
The maximum recommended number of clients per member is 100.
By default, members have core count * 20 threads that handle all the requests.
For example, if a member has 4 cores, it will have 80 threads available to handle requests.
Serialization in Client/Server Mode
In client/server topologies, you can serialize your data on the client side before sending it to a member. For example, you can serialize data in JSON and add it to a map. This option is useful if you plan on using Hazelcast to store your data in binary. Clients can handle serialization without the members needing to know how to do so.
For details about why you need to serialize data and the options for doing so, see Serialization.
