This package contains the MapReduce API definition for Hazelcast.
All map reduce operations running in a distributed manner inside the
active Hazelcast cluster. Therefor Mapper
,
Combiner
and Reducer
implementations need to be fully serializable by Hazelcast. Any of the
existing serialization patterns are available for those classes, too.
If custom KeyValueSource
is provided above
statement also applies to this implementation.
For a basic idea how to use this framework see Job
or Mapper
, Combiner
or
Reducer
.
