Distributed Map
Distributed Map is the most widely use data structure within Hazelcast IMDG. You can store objects directly from your application and get them back using the key or via SQL like queries. Everything is stored in memory with replicas spread across the cluster. Adding cluster members expands the space available for data. The example you can see here is in Java, but the API is similar across other languages. The Distributed Map can also recognise JSON values and allows querying on its elements.
