Hi Sean,
thanks for your help but we found another problem:
after we insert the valid json:
{ok,Pid} = riakc_pb_socket:start_link("10.10.10.74", 8087),
Value = mochijson2:encode({struct, [{id, 22}]}),
In = riakc_obj:new(<<"mm">>,<<"1">>,Value,"application/json"),
Marcel,
Sorry for the confusion, I missed one significant detail.
mochijson2:encode/1 will return an iolist (a list of lists and binaries).
Wrap the call to mochijson2:encode/1 in erlang:iolist_to_binary/1, like so:
Value = erlang:iolist_to_binary(mochijson2:encode({struct, [{id, 22}]})).
Hope t
I am trying to install Riak in my macbook. I installed erlang using "sudo port

and it quits.

Suresh,
We do not officially support R15B yet, but you can try changing the regex
in rebar.config to include R15.
{require_otp_vsn, "R14B0[234]|R15"}.
The above should do the trick.

Thanks Sean
I tried it. But it still reports the same issue. On other hand, is
it picking the regex from somewhere else, cos' i dont see the regex to match
r13b04 which it says is supported.
Thanks

Also, I uninstalled the older Erlang and installed, 14B03 sing the below set of
commands.
curl -O https://raw.github.com/spawngrid/kerl/master/kerl; chmod a+x kerl
./kerl build R14B03 r14b03
./kerl install r14b03 /opt/erlang/r14b03
. /opt/erlang/r14b03/activate
to resolve this version issue
Try cleaning out the directory with a
'make clean distclean pkgclean'
The regex to set the supported erlang version is in the rebar.config file if
you do want to change that.
And build again.

That cleared it up, thanks! Indeed, I was trying to add the index k/v as
regular meta in the headers.

Thanks Jared.
i ran the make clean command as you said, and it did work. but then it didnt
create the dev directory. I am only familiar with the instructions on how to
run a three node cluster ( dev1, 2 and 3) riak . I tried doing made devrel and
I get this error below.
I already set a three
The issue still prevails. After the make clean when i do a make all or make
devrel, it still says the version mismatch and quits. Altering the rebar.config
doesnt help either.
Thanks

If you are doing this from the source tarball, try blowing away the untar'd
directory and start from scratch. Something must be hanging around your build
directories if you no longer have r15B on your system.

This also has to be done for some of the deps so go through your riak/deps/*
dirs and correct rebar.config accordingly.
We run (although not in production yet) R15B on Mac OSX and Debian 6.0.

John,
To your first question, yes, it is possible that the client may receive a
failure response from Riak but the data could have persisted on some of the
nodes. This is because a single write to Riak is actually N writes to N
different partitions inside of Riak. These N writes are not atomic i
(Changing subject to reflect the problem better and reposting ).
Any idea , based on the configuration inline as to what explains the
inconsistency number of keys read after a bulk write ( say 1M of payload
1000 bytes ).
Any appropriate write flush setting , that is missed on the client / server
John,
As you already seem to understand, Riak doesn't provide a way to make
multiple ops atomic. Part of the reason is because Riak's main focus thus
far has been availability. Distributed transactions would work, but at the
cost of availability. I think a flaw with the redo log approach is tha
Hello All.
We currently have a large number of DL 380 HPs with 8 SAS disks in a
raid 10 for our Riak cluster. One of the ways in which we were considering
increasing performance is to move the Riak files off to SSD. Has anyone on the
list moved to SSDs? Have you any statistics on perform
I don't have any exact statistics, but I'm willing to personally guarantee
you will not be disappointed. Both Riak back ends are essentially doing
random IO, and in practice we've found our disks to be entirely bounded by
seek time.

If you are doing anything that will read from disk, SSDs will improve your
performance. If you are doing any reads from disk that are non-sequential,
SSDs will really increase your performance.

Thanks for the reply, which confirms what I expected.
Let me explain why I asked. I have an application that my intuition says would
be a good match to Riak, but I don't trust my intuition since I've never used
Riak and I'm not sure I understand all of its failure modes. One thing I'm
trying is
Right, I certainly don't want distributed transactions, which I agree would
destroy availability. (I should add that my system is geographically
distributed, making everything much worse.)
Still, that leaves open the question of doing what my application needs without
transactions. Let's consid
John, welcome to Riak and the forums.
Question 1: Availability.
Welcome to the list and thank you for the questions. I'm going to answer 1/3
and hopefully help you form your mental model a little bit better.
The short answer is that the odds of having the kind of _un_availability you

Not sure how your binding does it but MyBucket.keys() should be calling the
list keys feature of riak via the streaming mode which chunks the key reply
instead of buffering and sending one entire list of keys.

One thing to be aware of, in a multi-cluster setup such as you apparently
(will) have, is that cluster2cluster synchronization gives no ordering
guarantees:
Updates at one cluster on two different keys may arrive at the other cluster in
any order.
