PartitionHub.ConsumerInfo

All Known Subinterfaces:

PartitionHub.ConsumerInfo

Enclosing class:

PartitionHub
```
public static interface PartitionHub.ConsumerInfo
```
Sequence of all identifiers of current consumers.
Use this method only if you need to enumerate consumer existing ids. When selecting a specific consumerId by its index, prefer using the dedicated consumerIdByIdx(int) method instead, which is optimised for this use case.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`long`	`consumerIdByIdx(int idx)`	Obtain consumer identifier by index
`java.util.List<java.lang.Object>`	`getConsumerIds()`
`int`	`queueSize(long consumerId)`	Approximate number of buffered elements for a consumer.
`int`	`size()`	Number of attached consumers.

- Method Detail
  - consumerIdByIdx
```
long consumerIdByIdx(int idx)
```
    Obtain consumer identifier by index
  - getConsumerIds
```
java.util.List<java.lang.Object> getConsumerIds()
```
  - queueSize
```
int queueSize(long consumerId)
```
    Approximate number of buffered elements for a consumer. Larger value than other consumers could be an indication of that the consumer is slow.
    Note that this is a moving target since the elements are consumed concurrently.
