Stick with cql3 going forward. Last i checked, there is no further dev on
thrift. I had worked with Thrift based c* api for 2 years in Python based
pycassa and experience was not very satisfactory. I had not done comparisions
between pycassa and cql so cant say. Cql isvery simple any way.—

know how to fetch the timestamps. Are you just looking for python code to

By the way, there's a pycassa-specific mailing list here:

Hey folks,
I am dealing with a legacy CFs where super_column has been used and python
client pycassa is being used. An example is given below. My question here
is, can I make use of include_timestamp to select data between two
returned timestamps e.g between 1393516744591751 and
Hey Folks,
Does pycassa get column_start takes greater than equal to option? What I
know so far is, you have to exact column or super_column value for
column_start and column_finish to work. In my case, column is value of
epoch time.
I am in process of setting 2 node cluster with C* version 2.0.4. When I
started each node, it failed to communicate thus, each are running separate
and not in same ring. So started looking at the log files are saw the

I am used to working with CCM for testing. For production, I depend on
installing cassandra manually. Is there a proven tool to install and manage
multinode cassandra cluster? If you have any experience, please let me know.
Thank you Michael. I am trying out Priam as we speak and will post an
update of my experience with different tools. Again. Thank you. -- K

Try sstable2json and json2sstable. But it works on column family so you can
fetch all column family and iterate over list of CF and use sstable2json
tool to extract data. Remember this will only fetch on disk data do
anything in memtable/cache which is to be flushed will be missed. So run
