OverwriteShardSpec (druid-processing 28.0.0 API)

All Superinterfaces:

ShardSpec

All Known Implementing Classes:

NumberedOverwriteShardSpec
```
public interface OverwriteShardSpec
extends ShardSpec
```
ShardSpec for non-first-generation segments. This shardSpec is allocated a partitionId between PartitionIds.NON_ROOT_GEN_START_PARTITION_ID and PartitionIds.NON_ROOT_GEN_END_PARTITION_ID.

- Method Detail
  - getNumCorePartitions
```
default int getNumCorePartitions()
```
    The core partition concept is not used with segment locking. Instead, the AtomicUpdateGroup is used to atomically overshadow segments. Here, we always returns 0 so that the PartitionHolder skips checking the completeness of the core partitions.

  - withAtomicUpdateGroupSize
```

  - withAtomicUpdateGroupSize
```
OverwriteShardSpec withAtomicUpdateGroupSize(short atomicUpdateGroupSize)
```
  - sharePartitionSpace
```
default boolean sharePartitionSpace(PartialShardSpec partialShardSpec)
```
    Returns true if this shardSpec and the given PartialShardSpec share the same partition space. This shardSpec uses non-root-generation partition space and thus does not share the space with other shardSpecs.
