Re: Cloning a cluster / copying all cluster data

Matt, We copied all the data key by key, since we used incorrect 'ring_creation_size' value. ( http://riak-users.197444.n3.nabble.com/Cluster-migration-due-to-incorrect-quot-ring-creation-size-quot-value-td4024509.html ) So, you can use this copy tool - https://github.com/tovbinm/riak-tools, whic

Howdy Riak Users, Recently I discovered that my MapReduce job, that used to run successfully, stopped working. Here is the error: {"phase":0,"error":"[timeout]","input":"{<<\"test\">>,<<\"123\">>}","type":"forward_preflist","stack":"[]"} Is anyone familiar with this problem? How can I make it to

Re: Riak Recap for August 4 - 15

Mark, Thanks for the script! We've been using it for a couple of months already and it seems to be doing ok. But my current concern is - how can we measure the performance impact of calling "/stats/" on Riak nodes prior to 1.2? Maybe it is better to use the suggested scripts ( https://github.com/

Cluster migration due to incorrect "ring_creation_size" value

Hi Basho, We have a running cluster of 5 nodes which accidentally was configured with a default setting "{ ring_creation_size: 64 }". As suggested in documentation we cannot scale this cluster more than 6 machines, so the only option is to migrate to a new cluster with a larger ring_creation_size

Claude, 1. try to increase js_vm_counts as follows: {riak_kv, [ ... {map_js_vm_count, 24 }, {reduce_js_vm_count, 18 }, ...] 2. optimize your js function: query.map("""function(v) {if (v.values[0].data.search( '"""+search_string+"""') != -1) { retu

Efficient way of passing multiple arguments to mapreduce functions

Hi Riak-users, I'm looking for an efficient way of passing multiple arguments to mapreduce functions, Instead of passing a JSON (or other custom string representation of arguments) and being forced to parse it on every map/reduce function call, i.e.: Now: //Passing: arg = {"a":"0", "b":"1"} //Ex

Re: Riak Adoption - What can we do better?

Riak is one of the simplest KV stores I used so far. Almost zero learning curve and ease of setup makes it a great tool to start working with. Moreover, later you got rewarded by an outstanding stability and minimal maintenance even at large scale. So, the only obstacle I see in adoption of Riak

Good day! As previously discussed here ( https://github.com/basho/riak_kv/pull/252#issuecomment-4415767) I am unable to perform MR on my cluster due to wrong encoding in some of my values. What are the suggestions for solving this issue, except of cleaning data before putting it to Riak? Why

Hi Sean, Seems like a nice tool, but it's nice to have more examples on the homepage. Because currently I've a problem understanding if the tool is working at all: no connected nodes info is printed. See below. Similar happens with other diag commands, such as 'diag disk', 'diag dumps' etc. #~/
