NoSQLSubscriberId (Oracle NoSQL Database API)

java.lang.Object
- oracle.kv.pubsub.NoSQLSubscriberId

```
public class NoSQLSubscriberId
extends java.lang.Object
```
Object to represent a subscriber id in a subscription group. When user creates a subscription group with multiple subscribers, each covering a disjoint subset of shards, user need to specify the NoSQLSubscriberId for each subscriber in that group.
In addition to the checkpoint table name, the index consists of two parts, 1) the total number of subscribers in the group, and 2) the index of the given subscriber. The index must be fall in the range between 0 inclusively, and the total number of subscribers exclusively. For example, assume a subscription group with 3 subscribers, each covering a portion of the shards in source store, the index of the 3 subscribers should be 0, 1 and 2, respectively.
