##Restrictions

1. Supported Riak Versions: 1.2

2. Both clusters must have same ring size and node count.

Set allow_strfun true on all nodes:

echo "rpc:multicall([node() | nodes()], application,set_env,[riak_kv,allow_strfun,true])." | bin/riak attach

Insert 15000 keys:

for i in {1..15000}; do curl -XPUT http://127.0.0.1:9000/buckets/test/keys/test$i -H "content-type: text/plain" -d "Data #$i\n"; done
