Re: What is the best way to model my time series?

Hi, It sounds to me like Apache Kafka would be a better fit for your requirements. Have you considered that option? kr, Gerard Datastax MVP for Apache Cassandra (so, I'm not suggesting other tech for any other reason that seeing it as a better fit) On Fri, Mar 25, 2016 at 1:31 PM, K. Lawson

Re: Best way to get Cassandra status in Bash

(Hit enter too fast) In particular, `nodetool status` will give you a summary of the status of the cluster. See the documentation for the parameters it takes. -kr, Gerard. On Mon, Jan 4, 2016 at 3:49 PM, Gerard Maas <gerard.m...@gmail.com> wrote: > I think you are looking for the

I think you are looking for the nodetool utility: https://docs.datastax.com/en/cassandra/2.1/cassandra/tools/toolsNodetool_r.html On Mon, Jan 4, 2016 at 1:47 PM, Giovanni Usai wrote: > Hello, > I would gladly welcome the help of the community on the following issue

How are you loading the data? I mean, what insert method are you using? On Thu, Sep 24, 2015 at 9:58 PM, Benyi Wang wrote: > I have a cassandra cluster provides data to a web service. And there is a > daily batch load writing data into the cluster. > >- Without the

To batch or not to batch: A question for fast inserts

General advice advocates for individual async inserts as the fastest way to insert data into Cassandra. Our insertion mechanism is based on that model and recently we have been evaluating performance, looking to measure and optimize our ingestion rate. I side-tracked some punctual benchmarks and

Duplicating a cluster with different # of disks

Hi, I'm currently trying to duplicate a given keyspace on a new cluster to run some analytics on it. My source cluster has 3 disks and corresponding data directories (mnt, mnt2, mnt3) but the machines in my target cluster only have 2 disks (mnt, mnt2). What should be the correct procedure to
