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.—

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 1393516772131811.
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.
Hi Michael - Yes, 7000, 7001, 9042, 9160 are all open on EC2.
Issue was seeds address and listen_address were 127.0.0.1 and private_ip.
This will help anyone

Hey Folks - I am burning the midnight oil fast but cant figure out what I
am doing wrong? log files has this. I have also listed both seed node and
node 2 partial configurations.

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
message below:

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.
Hey folks,
I used create_column_family to create a CF but made a typo and I need to
use alter_column_family to drop that column and re-create with correct
name? Can you help with the syntax?
here is what I use for alter_column_family:
SYSTEM_MANAGER.alter_column_family('Narrative','Instagram_Tag
ts: 45, favorite: 34,
screen_name:'newname'}.
.
}
Is there something wrong with it? Here 1234555665_53323232 and
2344555665_53323232 are super columns. Also, If I have to represent this
data with new composite comparator, How will I accomplish that?
Please let me know.
Regards.

Hi Folks - I have having issue fetch data using pycassa get() function. I
have copied the CF schema and my code is below. This query returns me just

Hey Folks,
I have a row like this. 'twitter_row_key' is the row key and
411186035495010304 is column. Rest is values for 411186035495010304 column.
See below.

Hey Folks,
So I am creating, column family using pycassaShell. See below:
validators = {
'approved': 'BooleanType',
'text': 'UTF8Type',
'favorite_count':'IntegerType',
'retweet_count': 'IntegerType',
'expanded_url': 'UTF8Type',
'tuid': 'LongTy
What are the all possible values for cf_kwargs ??
SYSTEM_MANAGER.create_column_family('Narrative','Twitter_search_test',
comparator_type=UTF8Type, )
- Here I want to specify, Column data types and row key type. How can
I do that ?

I have worked with Pycassa before and wrote a wrapper to use batch mutation
& connection pooling etc. But
http://wiki.apache.org/cassandra/ClientOptions recommends
now to use CQL 3 based api because Thrift based api (Pycassa) will be
supported for backward compatibility only. Apache site recommends
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
compactio
