如何從cassandra會話中獲取密鑰空間名稱

Question

當我創建會話時，將keyspace_name用作API cluster.connect（keyspaceName）的輸入。是否/ api在哪里可以從會話中獲取keyspace_name？

會話創建

String cKeyspace="inventory_flip"
Session session = cluster.connect(cKeyspace);

如何從現有的cassandra DB會話中獲取密鑰空間？

session.getXXXXX?

Answer 1

public interface Session extends Closeable {

  /**
   * The keyspace to which this Session is currently logged in, if any.
   *
   * <p>This correspond to the name passed to {@link Cluster#connect(String)}, or to the last
   * keyspace logged into through a "USE" CQL query if one was used.
   *
   * @return the name of the keyspace to which this Session is currently logged in, or {@code null}
   *     if the session is logged to no keyspace.
   */
  String getLoggedKeyspace();
