  - getPipelineReductions
```
int getPipelineReductions()
```
    Returns the number of pipeline reductions an optimizer was able to do. If an optimizer cannot optimize the pipeline at all, then 0 should be returned.
    
    Returns:
    
    The number of pipeline reductions an optimizer was able to do
  - getSqlWhileCount
```
int getSqlWhileCount()
```
    Returns the number of while predicate expressions in the SQL query.
    
    Returns:
    
    the number of while predicate expressions in the SQL query
  - getSqlOrderCount
```
int getSqlOrderCount()
```
    Returns the number of order by columns in the SQL query.
    
    Returns:
    
    the number of order by columns in the SQL query
  - getSqlSkipCount
```
int getSqlSkipCount()
```
    Returns the number of skip statements (0 or 1) in the SQL query.
    
    Returns:
    
    the number of skip statements (0 or 1) in the SQL query
  - getSqlLimitCount
```
int getSqlLimitCount()
```
    Returns the number of limit statements (0 or 1) in the SQL query.
    
    Returns:
    
    the number of limit statements (0 or 1) in the SQL query
  - getSqlCount
```
default int getSqlCount()
```
    Returns the sum of getSqlWhileCount(), getSqlOrderCount() , getSqlSkipCount() and getSqlLimitCount().
    
    Returns:
    
    the sum of getSqlWhileCount(), getSqlOrderCount() , getSqlSkipCount() and getSqlLimitCount()
  - of

static Metrics of(int pipelineReductions,
                  int sqlWhileCount,
                  int sqlOrderCount,
                  int sqlSkipCount,
                  int sqlLimitCount)
```
    Creates and returns a new Metrics.
    
    Parameters:
    
    pipelineReductions - number of pipeline reductions that were made
    
    sqlWhileCount - the number of while predicates
    
    sqlOrderCount - the number of columns to sort by
    
    sqlSkipCount - the number of skip statements (0 or 1)
    
    sqlLimitCount - the number of limit statements (0 or 1)
    
    Returns:
    
    a new Metrics
  - empty
```
static Metrics empty()
```
    Returns an empty metrics. This can be used by optimizers that are unable to optimize the current stream.
    
    Returns:
    
    Returns an empty metrics
