Hi Mehdi, In addition, give some thought to your cluster topology. For maximum fault tolerance and availability I would recommend using at least three nodes with a replication factor of three. Ideally, you should also use Cassandra logical racks. This will reduce the risk of outage and make

hey there, In order to install cassandra, java has to be installed first. is that mean that the default driver of cassandra is java? what if we wanna use the cpp driver? P.S 1: my questions might be so dump, but I will really appreciate an answer. PS 2: I'm intern and i'm completely new to

Single Node Cassandra Installation

Hey Guys, What should I look out for when deploying a single node installation? We want to launch a product that uses Cassandra and since we are going to have very little load initially, we were thinking of just going live with one node and eventually add more nodes as the load (hopefully)

Re: Single Node Cassandra Installation

Should be fine if one node can deal with your read and write load. Switching from SimpleStrategy to RackAware can be a pain. That¹s a potential growth point way down the line (if you ever have your nodes on different switches). You might want to just setup your keyspace as RackAware if you intend

Re: Single Node Cassandra Installation

I understand that with one node we will have no HA, but since we are just starting out we wanted to see what would be the bare minimum to go to production with and as we see traction we can add more nodes. Switching from SimpleStrategy to RackAware can be a pain. Can you elaborate a bit? What

Re: Single Node Cassandra Installation

Even more: if you enable read repair the chances of having bad writes decreases for any further reads. This will make your cluster become faster consistent again after some failure. Under 1.0 the default RR probability was reduced to 10%. Because Hinted Handoff was changed to also store

Re: Single Node Cassandra Installation

By default Cassandra tries to write to both nodes, always. Writes will only fail (on a node) if it is down, and even then hinted handoff will attempt to keep both nodes in sync when the troubled node comes back up. The point of having two nodes is to have read and write availability in the face

Re: Single Node Cassandra Installation

You'll need to either read or write at at least quorum to get consistent data from the cluster so you may as well do both. Now that you mention it, I was wrong about downtime, with a two node cluster reads or writes at quorum will mean both nodes need to be online. Perhaps you could have an

Re: Single Node Cassandra Installation

Doing reads and writes at CL=1 with RF=2 N=2 does not imply that the reads will be inconsistent. It's more complicated than the simple counting of blocked replicas. It is easy to support the notion that it will be largely consistent, in fact very consistent for most use cases. By default

Single Node Cassandra Installation

Hi, We are working on a project that initially is going to have very little data, but we would like to use Cassandra to ease the future scalability. Due to budget constraints, we were thinking to run a single node Cassandra for now and then add more nodes as required. I was wondering if it is

Re: Single Node Cassandra Installation

Hi Drew, One other disadvantage is the lack of consistency level and replication. Both ware part of the high availability / redundancy. So you would really need to backup your single-node-cluster to some other external location. Good luck! 2012/3/15 Drew Kutcharian d...@venarc.com Hi, We

Re: Single Node Cassandra Installation

So long as data loss and downtime are acceptable risks a one node cluster is fine. Personally this is usually only acceptable on my workstation, even my dev environment is redundant, because servers fail, usually when you least want them to, like for example when you've decided to save costs by
