List Connector
A list is a simple data structure which is ordered, and not
partitioned. All the contents of the IList
will reside only on one
member.
Installing the Connector
This connector is included in the full and slim distributions of Hazelcast.
Permissions
Enterprise Edition
If security is enabled, you can set up permissions to restrict clients' access to these data structures. For details, see Client Authorization.
List as a Source or Sink
The API for it is very limited, but is useful for simple prototyping:
IList<Integer> inputList = hz.getList("inputList");
for (int i = 0; i < 10; i++) {
inputList.add(i);
}
Pipeline p = Pipeline.create();
p.readFrom(Sources.list(inputList))
.map(i -> "item-" + i)
.writeTo(Sinks.list("resultList"));
List isn’t suitable to use as a streaming sink because items are always appended and eventually the member will run out of memory. |
