Currently these are two different types of query, using a key range is

You could build a custom secondary index where column=value is the key and
startKey and endKey are column names. Then call get_count() with a

: Query on delete a column inside a super column
Hi,
Thanks for the reply,
The remove method
$cassandraInstance-remove('cache_pages_key_hash', 'hash_1' )
which will remove the whole key, But I don't want to do that, I need to remove
one column inside that key
Can you please tell me how to use

For examples(described in Python):
Schema:
# columnfamily name
resources = [
# key
'foo': {
# columns and value
'url': 'foo.com',
'pushlier': 'foo
where the key equals
mmalone).
See the get_range_slices() method in the thrift service.

filters ( like show me
only likes from a given user). This would include range query to support
pagination. So this would mean indices on a few columns like the feed id,
feed type etc.
