Hi, I think I've spotted an issue with the configuration snippets
given on both these pages, relating to configuring Riak CS.. but it
might just be my misunderstanding of Erlang configuration formats.
http://docs.basho.com/riakcs/latest/tutorials/fast-track/Building-a-Local-Test-Environment/
http://docs.basho.com/riakcs/latest/cookbooks/configuration/Configuring-Riak/
On those pages, none of the names of backends are quoted. ie. We
have {be_blocks, riak_kv_bitcask_backend, rather than:
{<<"be_blocks"">, riak_kv_bitcask_backend,
Both of those links look correct to me.
And I agree that they do work as given.. just you lose the ability to
refer to backends by name when setting bucket properties.
Which you're not going to do for RiakCS buckets, but you would if you
want to have other buckets for use by your app.
However in the regular Riak configuration section, backend names
are always quoted.
Can you provide a link to this?
Sure, it was from here:
http://docs.basho.com/riak/latest/tutorials/choosing-a-backend/Multi/
{multi_backend_default, <<"bitcask_mult">>},
{multi_backend, [
%% Here's where you set the individual multiplexed backends
{<<"bitcask_mult">>, riak_kv_bitcask_backend, [
%% bitcask configuration
{config1, ConfigValue1},
{config2, ConfigValue2}
]},
Now, I note that if you use the entire configuration snippet
verbatim, that it all works. However if you want to set more
backends and to select them via REST bucket properties, then you
find that none of the backends can be found.
Can you elaborate what you mean here? It's also worth mentioning
that, if you're using Riak CS, you shouldn't need to add or 'select'
more backends for the underlying Riak cluster.
Not for RiakCS, but what if you want to have a different backend
available for your app to use - eg. Memory or expiring Bitcask?
(You can use the backend prefix option, but that's not available in
regular Riak)
Things only seemed to work as expected once I went through and
quoted all the backend names - in the multi_backend{} part, and
also for the prefix_list and default options.
