- Method Detail
  - earliest
```
reactor.core.publisher.Mono<ChangeIdentifier> earliest()
```
    Returns the change identifier for the earliest available change.
    
    Returns:
    
    change identifier
  - current
```
reactor.core.publisher.Mono<ChangeIdentifier> current()
```
    Returns the change identifier for the last committed transaction.
    
    Returns:
    
    change identifier
  - query
```
reactor.core.publisher.Flux<ChangeEvent> query(ChangeIdentifier from)
```
    Returns the changes that happened to the database after the given change identifier. The returned Flux completes when we reach the end of change stream.
    
    Parameters:
    
    from - change identifier to query changes from.
    
    Returns:
    
    change events
  - stream
```
reactor.core.publisher.Flux<ChangeEvent> stream(ChangeIdentifier from)
```
    Returns the changes that happened to the database after the given change identifier. The returned Flux does not complete, and continues querying for new changes until the Flux subscription is closed.
    Change Data Capture feature currently does not support streaming, and this method mimics streaming through polling.
    
    Parameters:
    
    from - change identifier to query changes from.
    
    Returns:
    
    change events
