I need more time to examine the diagram, but this all looks as expected so far.
If a client sends no context then it’s write will be a sibling of whatever is
stored at the coordinator, as you rightly point out riak treats an incoming

I doubt it is sibling explosion as 2.1.1 has DVV by default, and the config has
100 max siblings declared. But it may be, I guess.
Can you send me crash logs, or even the crash dump so I can get a better idea?
I mean, it surely looks like a memory leak of some kind.

Hi Paulo,
Riak-erlang-client does not support multiplexing. In fact I believe there would

If you just send the add operation the client doesn’t need to fetch the value
first, no. But riak, inside the vnode, will still do a local read at the
coordinating vnode.

The paid version has multi-datacenter replication, so yes, more reliable in
that you can lose a datacenter and stay available. The OS riak is in no-way

Right now, a map is just a riak object.
I guess with Riak Search indexing though, you could get something similar,

What version of riak_kv is behind this riak_cs install, please? Is it really
2.1.3 as stated below? This looks and sounds like sibling explosion, which is
fixed in riak 2.0 and above. Are you sure that you are using the DVV enabled
setting for riak_cs bucket properties? Can you post your bucket

But I still don’t understand _why_? What is the aim, ‘cos I’m not sure it’s
possible.
For quorum reads on indexes then Sargun’s “roll your own” idea is the better
answer at the moment.

Depends on what backend you are running, no? If leveldb then this list keys
operation can be pretty cheap.
It’s a coverage query, but if it’s leveldb at least you will seek to the start
of the bucket and iterate over only the keys in that bucket.

Hi,
Riak's secondary indexes require a sorted backend, either of the memory or
leveldb backends will work, bitcask does not support secondary indexes.
More details here

or others solr makes more sense. I
personally disagree with the statement at the top of

IF you use leveldb, there is a function in the riak-erlang-client that gets all
objects in a bucket, I don’t know if it has been implemented in the java client
as it was written specifically for riak-cs.

It’s worth noting that secondary indexes (2i) has some other advantages over
solr search. If you _can_ model your queries in 2i then I'd recommend it.
Secondary indexes have a richer API than is currently documented, if you look
at https://docs.basho.com/riak/1.4.7/dev/using/2i/ you’ll see that
What operation are you performing? It looks like the map is a single level map
of last-write-wins registers. Are you updating a value? Is there a chance that
the time on the node handling the update is behind the value in the
lww-register?
Have you tried using the `modify_type` operation in ria

ble thing and that still fails, it helps.
IMO the simplest possible thing is to start with a new, empty key and use
modify_type to update a single register.
Many thanks

Hi Andrey,
The register inside a map is a LWW-register.
Long story: When we added CRDTs to Riak we did it for those users who wanted to
avoid writing custom sibling resolution code, following on from that decision
we decided not to add the MVRegister type. Riak’s default object is an
MVRegister
