SSTableMetadata (apache-cassandra API)

```
public class SSTableMetadata
extends java.lang.Object
```
Metadata for a SSTable. Metadata includes: - estimated row size histogram - estimated column count histogram - replay position - max column timestamp - compression ratio - partitioner - generations of sstables from which this sstable was compacted, if any - tombstone drop time histogram An SSTableMetadata should be instantiated via the Collector, openFromDescriptor() or createDefaultInstance()
