Interface HazelcastConfigurer

All Known Implementing Classes:
JdbcHazelcastConfigurer
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface HazelcastConfigurer
Strategy interface for building a Hazelcast Config programmatically.

The default implementation is JdbcHazelcastConfigurer, which configures Hazelcast with a JDBC data source for persistence. In standalone mode an embedded H2 database is used automatically; in clustered mode an external JDBC URL must be supplied.

Advanced users can implement this interface to supply a fully custom Hazelcast configuration. Those who prefer file-based configuration can delegate to HazelcastConfigLoader.load(String, java.util.Map) inside their implementation to base it on a YAML or XML descriptor.
