public interface DatabasePipelineCommands

  • Method Details

    • select

      Response<String> select(int index)
      Select the DB with having the specified zero-based numeric index.
      Parameters:
      index - the index of db
      Returns:
      OK

    • dbSize

      Response<Long> dbSize()
      Return the number of keys in the currently-selected database.
      Returns:
      The number of keys

    • swapDB

      Response<String> swapDB(int index1, int index2)
      This command swaps two Redis databases, so that immediately all the clients connected to a given database will see the data of the other database, and the other way around.
      Parameters:
      index1 -
      index2 -
      Returns:
      OK

    • move

      Response<Long> move(String key, int dbIndex)
      Move the specified key from the currently selected DB to the specified destination DB. Note that this command returns 1 only if the key was successfully moved, and 0 if the target key was already there or if the source key was not found at all, so it is possible to use MOVE as a locking primitive.
      Parameters:
      key - The specified key
      dbIndex - Specified destination database
      Returns:
      1 if the key was moved, 0 if the key was not moved because already present on the target DB or was not found in the current DB

    • move

      Response<Long> move(byte[] key, int dbIndex)
      Binary version of MOVE.

    • copy

      Response<Boolean> copy(String srcKey, String dstKey, int db, boolean replace)
      Copy the value stored at the source key to the destination key.
      Parameters:
      srcKey - The source key.
      dstKey - The destination key.
      db - Allows specifying an alternative logical database index for the destination key.
      replace - Removes the destination key before copying the value to it, in order to avoid error.

    • copy

      Response<Boolean> copy(byte[] srcKey, byte[] dstKey, int db, boolean replace)
      Binary version of COPY.

      Response<String> migrate(String host, int port, String key, int destinationDB, int timeout)
      Migrate Command Atomically transfer a key from a source Redis instance to a destination Redis instance. On success the key is deleted from the original instance and is guaranteed to exist in the target instance.
      Parameters:
      host - Target host
      port - Target port
      key - Migrate key
      destinationDB - Target db
      timeout - The maximum idle time in any moment of the communication with the destination instance in milliseconds.
      Returns:
      OK on success, or NOKEY if no keys were found in the source instance

      host - Target host
      port - Target port
      destinationDB - Target db
      timeout - The maximum idle time in any moment of the communication with the destination instance in milliseconds.
