public interface ShardSpec
```
A Marker interface that exists to combine ShardSpec objects together for Jackson. Note that this is not an extension API. Extensions are not expected to create new kinds of ShardSpecs.

- Method Detail
  - createChunk
```
<T> PartitionChunk<T> createChunk(T obj)
```
  - getPartitionNum
```
int getPartitionNum()
```
    Returns the partition ID of this segment.
  - getNumCorePartitions
```
int getNumCorePartitions()
```
  - getStartRootPartitionId
```
default int getStartRootPartitionId()
```
    Returns the start root partition ID of the atomic update group which this segment belongs to.
    
    See Also:
    
    AtomicUpdateGroup
  - getEndRootPartitionId
```
default int getEndRootPartitionId()
```
    Returns the end root partition ID of the atomic update group which this segment belongs to.
    
    See Also:
    
    AtomicUpdateGroup
  - getMinorVersion
```
default short getMinorVersion()
```
    Returns the minor version associated to the atomic update group which this segment belongs to.
    
    See Also:
    
    AtomicUpdateGroup
  - getAtomicUpdateGroupSize
```
default short getAtomicUpdateGroupSize()
```
    Returns the atomic update group size which this segment belongs to.
    
    See Also:
    
    AtomicUpdateGroup
  - getLookup
```
ShardSpecLookup getLookup(List<? extends ShardSpec> shardSpecs)
```
  - getDomainDimensions
```
List<String> getDomainDimensions()
```
    Get dimensions who have possible range for the rows this shard contains.
    
    Returns:
    
    list of dimensions who has its possible range. Dimensions with unknown possible range are not listed
  - possibleInDomain
```
boolean possibleInDomain(Map<String,com.google.common.collect.RangeSet<String>> domain)
```
    if given domain ranges are not possible in this shard, return false; otherwise return true;
    
    Returns:
    
    possibility of in domain
  - getType
```
default String getType()
```
    Get the type name of this ShardSpec.
  - sharePartitionSpace
```
default boolean sharePartitionSpace(PartialShardSpec partialShardSpec)
```
    Returns true if this shardSpec and the given PartialShardSpec share the same partition space. All shardSpecs except OverwriteShardSpec use the root-generation partition space and thus share the same space.
