Hi all,
I am using Astyanax and Hector client within an application but right now I
am hitting a dependency issue [1] related to Guava version being used by
Hector and Astyanax which makes Maven headache. I have taken it out as

Hi all,
I am trying to migrate some some Hector's RangeSlicesQuery to Astyanax, but
the only method I have found is getKeyRange[1] which in turn has four
parameters startKey,endKey, startToken, endToken, and count.
The thing is that I am not sure what are the startToken and endToken
parameters u
Hey Shamim,
Why do you say that Java-Driver has better performance over Hector or
Astyanax? Is there any reasons for this?
Thanks.

Sorry to hijack into this email thread, but what are the use
cases/benefits of using the new binary protocol? and why doesn't
Cassandra offer a drive as a project driver?

Hi all,
I am using some composite keys to get just some specific composite
columns names which I am using as follows:

and default_validation_class = 'UTF8Type';

I am facing some problems while retrieving a some events from a column

The thing is that now I want to find out the latest event and I don't

Hi there,
I am sorry to get into this thread with more questions but isn't the
gossip protocol in charge of making the read_repair automatically
anytime a new node comes into the ring? I mean if a node is down, then
we get that node up and running again, wouldn't it be synchronized
automatically?
but I don't recall any API available (Hector or
> otherwise) which allows you to search based on the timestamp value.

Hi all,
I am trying to get all columns from a certain number of records I am
fetching. I am using the RangeSlicesQuery to achieve this, but it
forces me to set how many columns I want to be retrieved.
RangeSlicesQuery rangeSlicesQuery = HFactory

Hi all,
I have started playing around with Cassandra and I am not sure which
Avro data types Cassandra supports. Is there any type of documentation
or could anyone please help me on this doubt of mine?
Thanks!
