for the function get_slice, there is an argument *offset*. what does that
do? whatever value i pass to it, the cassandra server receives it as the
argument *limit*?
this is the python code:
>>> client.get_slice(tablename='Table1', key='1', columnParent='Standard1',
start='', finish='', isAscending=True, *offset=-1*, count=1000)

this is the debug log from cassandra.
DEBUG - weakreadlocal reading SliceFromReadCommand(table='Table1', key='1',
columnFamily='Standard1', isAscending='true', *limit='-1'*, count='1000')

you can see that i passed the value -1 to offset and in the cassandra server
log, it is received as the argument limit.
offset and limit mean different things right? is this a problem in python
client? or am i missing something here?
thanks
