Jonathan Hseu updated CASSANDRA-649:
------------------------------------
Description:
Here's an example using my python library ( http://github.com/vomjom/pycassa ):
>>> import pycassa
>>> connect = pycassa.connect()
>>> cf = pycassa.ColumnFamily(connect, 'Test Keyspace', 'Test Super',
>>> super=True)
>>> cf.insert('key1', {'2': {'sub3': 'val3', 'sub4': 'val4'}})
>>> cf.get('key1')
{'2': {'sub4': 'val4', 'sub3': 'val3'}}
>>> cf.get('key1', super_column='2')
{'sub4': 'val4', 'sub3': 'val3'}
>>> cf.multiget(['key1'])
{'key1': {'2': {'sub4': 'val4', 'sub3': 'val3'}}}
>>> cf.multiget(['key1'], super_column='2')
{'key1': {'sub4': 'val4', 'sub3': 'val3'}}
>>> list(cf.get_range())
[('key1', {'2': {'sub4': 'val4', 'sub3': 'val3'}})]
>>> list(cf.get_range(super_column='2'))
[('key1', {'2': {'sub4': 'val4', 'sub3': 'val3'}})]
In the last case, I expected:
[('key1', {'sub4': 'val4', 'sub3': 'val3'})]
If the super_column argument is supplied, then all of these make a ColumnParent
with:
cp = ColumnParent(column_family=self.column_family, super_column=super_column)
Or basically, in the KeySlice returned by get_range_slice(), if super_column
was set in the passed in the ColumnParent, the columns member of the KeySlice
should be a list of respective SuperColumn.columns and not a list of
SuperColumn.
Another way to describe the problem:
get_slice(), multiget_slice(), and get_range_slice() all return:
list<ColumnOrSuperColumn> in their return values in some way or another.
If super_column is set in the ColumnParent then:
1. get_slice() and multiget_slice() return the list of SuperColumn.columns each
wrapped in a ColumnOrSuperColumn
2. The KeySlice in get_range_slice() returns a list of ONE SuperColumn wrapped
in a ColumnOrSuperColumn

> multiget_slice() when super_column is set in ColumnParent
