crdtdb: A Riak Core Application

#Instructions Compile Riak using devrel

Make a devrel release of the crdtdb repo, it will assign the ports to match Riak's devrel

Start a Riak node

Create a last writer wins bucket curl -X PUT -H 'Content-Type: application/json' -d '{"props":{"last_write_wins":true, "n_val":3}}' "http://localhost:10018/buckets/ITEMS/props"

Start a crdtdb node

crdtdb/dev/dev1/bin/crdtdb start

Initialize the nodes

erl -name 'client@127.0.0.1' -setcookie crdtdb

rpc:call('crdtdb1@127.0.0.1', crdtdb, start, [id0, [{id0,'crdtdb1@127.0.0.1'}]]).

*id0 is the DC identifier

• [{id0,'crdtdb1@127.0.0.1'}] is a list of server nodes

Clear the database

erl -name 'client@127.0.0.1' -setcookie crdtdb

rpc:call('crdtdb1@127.0.0.1', crdtdb, reset, [id0,0,5,[{id0,'crdtdb1@127.0.0.1'}]]).

• id0 is the local 1
• 0 is the max key id
• 5 is the initial value
• [{id0,'crdtdb1@127.0.0.1'}] is a list of server nodes

Try some commands

erl -name 'client@127.0.0.1' -setcookie crdtdb

rpc:call('crdtdb1@127.0.0.1', crdtdb, decrement, [<<"0">>]).
