- Method Detail
  - getPartitionInfo
```
public abstract TimePartitionInfo getPartitionInfo(long instant)
```
    returns the directory where this instant shall be written. This is likely to be expensive operation - since instant has to be converted into a calendar taking into accounts leap seconds and all the rest.
    
    Parameters:
    
    instant -
  - parseDir
```
public abstract TimePartitionInfo parseDir(String dir)
```
    Parses a string of the shape "A/B/..." into a PartitionInfo. It is used by the storage engines to parse the partitions from disk at startup. Returns null if the given string does not match the expected directory.
  - getInstance
```
public static TimePartitionSchema getInstance(String schema)
```
  - getName
```
public String getName()
```
    name for the partitioning schema (YYYY/DOY, YYYY/MM, etc)
    
    Returns:
