# Terminology:
# Explicit disk column : A column that has 'storage disk' definition.
# Implicit disk column : A column that has default storage and thus inherits
# its storage from the table having 'storage disk' definition.

#
# This test tests the following cases :
#   Moving column data between disk and memory will be performed
#     with copy algorithm
#   Create a table and an index on a column having explicit and implicit disk
#     columns

# Create logfile group
CREATE LOGFILE GROUP lg1
  ADD UNDOFILE 'lg1_undofile.dat'
  INITIAL_SIZE 1M

# Create tablespace using the logfile group
CREATE TABLESPACE ts1
  ADD DATAFILE 'ts1_datafile.dat'
  USE LOGFILE GROUP lg1
  INITIAL_SIZE 10M
  ENGINE ndb;


## Move columns between memory and disk storage and
##  verify whether the copy algorithm is used.
