Adding to conversation...
there are 3 great open source options available
1. Calliope http://tuplejump.github.io/calliope/
This is the first library that was out some time late last year (as i
can recall) and I have been using this for a while, mostly very stable,
uses Hadoop i/o in Cassandra
2. "still uses thrift for minor stuff" --> I think that the only call using
thrift is "describe_ring" to get an estimate of ratio of partition keys
within the token range
3. Stratio has a talk today at the SF Summit, presenting Stratio META. For
the folks not attending the conference, video should
Ok.
DataStax , Startio are required mesos, hadoop yarn other third party to
get spark cluster HA.
What in case of calliope?
Is it sufficient to have cassandra + calliope + spark to be able process
aggregations?
In my case we have quite a lot of data so doing aggregation only in memory

Hi Oleg,
I am the creator of Calliope. Calliope doesn't force any deployment
model... that means you can run it with Mesos or Hadoop or Standalone. To
be fair I don't think the other libs mentioned here should work too.
The Spark cluster HA can be provided using ZooKeeper even in the standalone

What are you referring to when you say memory store?
RAM disk? memcached?
Thanks,

Thanks for this new version that seems to bring a lot of new interesting
features and improvements !
Definitely interested in trying new counters and incremental repairs.
Congrats.
PS: I am also quite curious to know what is still inside the heap :D. Maybe
key cache ? So what is recommended heap

One question. Where can users get a java Datastax driver to support this
version? If so is it released?

jbellis talked about incremental repair, which is great, but as I understood,
repair was also somewhat responsible for detecting and repairing bitrot on
long-lived sstables.
If repair doesn't do it, what will?

Do you have some crazy workload where you do a huge amount of delete or
something? Replaying a commitlog should not take longer th
Ok is it part of the release or needs to be downloaded from Datastax somewhere.
I am wondering about the java driver.
Thanks!

When setting up a new (additional) data center, the documentation tells us
to use "nodetool rebuild -- " to fill up the node(s) in the new dc,
and to disable auto_bootstrap.
I'm wondering if it is possible to fill the node with "auto_bootstrap=true"
instead of a nodetool rebuild command. If so, ho

Thanks, Rob.
I actually tried using LOCAL_ONE instead of ONE, but I still saw this
problem. Maybe I missed some queries when updating to LOCAL_ONE. Anyway,
it's good to know that this is supposed to work.
