### Question:
MemStore extends DataStoreBase<K, T> { @Override public void deleteSchema() { if (!map.isEmpty()) { map.clear(); } }  @Override String getSchemaName(); @Override boolean delete(K key); @Override long deleteByQuery(Query<K, T> query); @SuppressWarnings("unchecked") @Override Result<K, T> execute(Query<K, T> query); @SuppressWarnings("unchecked") @Override T get(K key, String[] fields); @SuppressWarnings("unchecked") @Override boolean exists(K key); @Override Query<K, T> newQuery(); @SuppressWarnings("unchecked") @Override void put(K key, T obj); @Override /** * Returns a single partition containing the original query */ List<PartitionQuery<K, T>> getPartitions(Query<K, T> query); @Override void close(); @Override void createSchema(); @Override void deleteSchema(); @Override boolean schemaExists(); @Override void flush(); @SuppressWarnings("rawtypes")
  static ConcurrentSkipListMap map; }### Answer:
@Test @Ignore("MemStore has no concept of a schema") public void testDeleteSchema() throws Exception {}
