- Method Detail
  - getStatus
```
String getStatus()
```
    The database history starts in STOPPED state. Upon start it transitions to RECOVERING state. When all changes from stored history were applied then it switches to RUNNING state.
    Maps to DatabaseHistoryMetrics.DatabaseHistoryStatus enum.
    
    Returns:
    
    database history component state
  - getRecoveryStartTime
```
long getRecoveryStartTime()
```
    Returns:
    
    time in epoch seconds when recovery has started
  - getChangesRecovered
```
long getChangesRecovered()
```
    Returns:
    
    number of changes that were read during recovery phase
  - getChangesApplied
```
long getChangesApplied()
```
    Returns:
    
    number of changes that were applied during recovery phase increased by number of changes applied during runtime
  - getMilliSecondsSinceLastAppliedChange
```
long getMilliSecondsSinceLastAppliedChange()
```
    Returns:
    
    elapsed time in milliseconds since the last change was applied
  - getMilliSecondsSinceLastRecoveredChange
```
long getMilliSecondsSinceLastRecoveredChange()
```
    Returns:
    
    elapsed time in milliseconds since the last record was recovered from history
  - getLastAppliedChange
```
String getLastAppliedChange()
```
    Returns:
    
    String representation of the last applied change
  - getLastRecoveredChange
```
String getLastRecoveredChange()
```
    Returns:
    
    String representation of the last recovered change
