Re: Cluster ready status for Riak S2

[Jhonny Everson]

Thank you Mark,

I end up adding some markers on image initialization and I watch the docker
container logs for this message before trying to use the instance.

I tried using riak-cs ping, but unfortunately the ping was not enough. e.g.
sometimes the riak kv was still initialising when I got a ping response
from riak-cs.

Re: Cluster ready status for Riak S2

[Vitaly E]

Actually, 'riak-admin wait-for-service  ' can be a good
way of checking if a Riak service has fully started. For example, 'riak-admin
wait-for-service riak_kv riak@127.0.0.1' (
http://docs.basho.com/riak/latest/ops/running/tools/riak-admin/#wait-for-service,
more details in http://littleriakbook.com/). This command will exit when
the service is finally up. A list of available services can be printed using
'riak-admin services'. I believe it should work with Riak S2 as well as
Riak KV.

Best,
Vitaly

Riak Recap March 18, 2016

[Alexander Sicular]

Hi Shailesh,

I hadn't heard of JugglingDB. Looks interesting. There is no riak adapter
for it as far as I know. There is, however, a riak client library for
nodejs[0]. So I imagine an adapter could be written. Looking through the
examples in the read me it looks like solr would have to be used to
implement certain features.

How many folks out there would like to use something like juggling or
waterline?
