Examples of Tablespace

com.splout.db.common.Tablespace
A tablespace is made up by:
- A {@link PartitionMap}
- A {@link ReplicationMap}
- A version string
- A creation date
The Tablespace entity is necessary for safely storing each tablespace's information in memory and atomically updating it, for instance in {@link com.splout.db.qnode.QNodeHandler}.

Examples of com.splout.db.common.Tablespace

      replicationEntries.add(repEntry);
    }
    // A valid partition map is complete: first min is null and last max is null.
    partitions.get(0).setMin(null);
    partitions.get(partitions.size() - 1).setMax(null);
    return new Tablespace(new PartitionMap(partitions), new ReplicationMap(replicationEntries), 0l, 0l);
  }
