Re: Changing ring size on 1.4 cluster

Alex,

While a command does exist to resize the ring in Riak 2, it is for all
intents and purposes deprecated.

The best solution, as always, is to benchmark your cluster's
performance using real world load, and plan for a bit of head room if
expansion is likely.

Re: Changing ring size on 1.4 cluster

[Alex De la rosa]

Can the ring size be changed easily in Riak 2.X?

Imagine I have 5 servers originally with a ring_size = 64... If later on I
add 5 more servers (10 in total) and I also want to duplicate the
partitions, can I just edit the ring_size to 128?

How would be the process to do it? Will it rebalance properly and have no
issues?

Thanks,
Alex

[Luke Bakken]

Hi Johnny,

Yes, the latter two are your main options. For a 1.4 series Riak
installation, your only option is to bring up a new cluster with the
desired ring size and replicate data.

Re: Changing ring size on 1.4 cluster

[Alex De la rosa]

Hi there,

I'm interested on knowing how to increase the cluster's ring too... i'm
using Riak 2.X though... any documentation around on how to play with the
number of servers/partitions?

Thanks,
Alex
