Re: [Announcement] Riak 2.1 - Features & Release Notes

[Sean Cribbs]

Alex,

We require bucket types for the write-once feature for the same reason we
require them for datatypes or strong consistency: this is a property that
changing after data has been written could have undefined behavior. Making
there be an explicit creation/activation of the bucket-type ensures that
the behavior on the namespace created by the bucket-type never changes.
However, old or "default" buckets may be changed at any time -- meaning we
can't ensure safety of any property changes.

Thanks for your answers.

Good point noticed about the middleware.

May I ask what middleware would you suggest to be evaluated?

Re: [Announcement] Riak 2.1 - Features & Release Notes

[Alex De la rosa]

"The write_once property is applied to a bucket type"... why only on bucket
types?

ex: RIAK.bucket_type('my_type').bucket('my_bucket').get('my_key')

Normally I use bucket types to use mutable data like Maps/Sets/Counters...
so I can update its contents (multiple writes) and when I have static data
I use a basic buckets:

ex: RIAK.bucket('my_bucket').get('my_key')

It makes much more sense to me to have write_once capabilities in this kind
of bucket that not in a bucket type bucket. I can imagine the use of a
bucket type just for indexing data in Solr and not change it... but I think
simple buckets would benefit of this feature even more.

Thanks!
Alex

[Announcement] Riak 2.1 - Features & Release Notes

[Matthew Brender]

Riak 2.1 is available [1]! Let’s start with the most fun part.


## New Feature
Riak 2.1 introduces the concept of “write once” buckets, buckets whose
entries are intended to be written exactly once, and never updated or
over-written. The write_once property is applied to a bucket type and
may only be set at bucket creation time. This allows Riak to avoid a
"read before write" for write_once buckets only. More information, as
always, is available in the docs [2]


## Other updates
There are a number of GitHub Issues closed with the 2.1 release. Some
noteworthy updates:

* A nice solution for a corner case that could result in data loss [3]
* A public API related to riak_core_ring_manager thanks to Darach Ennis! [4]
* A JSON writer for a number of riak_admin commands - see commit for details [5]
* Updates to Yokozuna (Riak’s Solr integration) that include
additional metrics thanks to Jon Anderson! [6]

Be sure to see the full Release Notes here [7] and the Product Advisories [8].

## Upgrading
Be sure to review documentation [7] before an upgrade. It’s worth
noting that all nodes in a cluster must be at 2.1 before you set the
write_once property on a bucket.

It’s worth noting that there is a known issue with Yokozuna that
causes entry loss on AAE activity [9]. Please keep this in mind before
upgrading.


## Feedback please
Do you have a use case where write_once could be helpful? Please reply
to me directly! I would love to learn about your environment and be
able to share more details with you.

Matt

That is, if I want to develop an Android app that connects to a Riak

 I am using Mac OS 10.10 and the solution was to remove the firts slash from

Re: object sizes

[Alex De la rosa]

Hi Matthew,

Thanks for your answer : ) i always have interesting questions : P

about point [2]... if you see my examples, i'm already using
sys.getsizeof()... but sizes are not so accurate, also, I believe that is
the size they take on RAM when loaded by Python and not the full exact size
of the object (specially on Maps that differs quite some).

I will open the ticket then : ) I think it can be very helpful future
feature.

Thanks,
Alex

Re: object sizes

Hi Alex,

That is an interesting question! I haven't seen a request like that in
our backlog, so feel free to open a new issue [1]. I'm curious: why
not use something like sys.getsizeof [2]?

 You can always query the size of a riak object using `curl` and the REST

 i.e. curl -I :8098/buckets/test/keys/demo

Re: Riak 2.0 Pre/Post commit

[Matthew Brender]

Hi Humberto,

Excuse the delay here - this question slipped through. Can you walk
through what you're trying to do?

When it comes to hook examples, the best examples are kept up-to-date
on this page [1]. I found one example from this blog post [2] which
you can jump to by searching the page for "% pre- and post-commit hook
functions."

Re: Need help getting riak started

[Shawn Debnath]

Turns out it was the nodename that was the culprit. The suffix part of the 
nodename, @cluster.example.com, needs to be resolvable to that specific host 
for ping to work. So had to switch to n...@node.cluster.example.com. Though it 
looks strange, at least the service boots up properly.

Attempted to get it to work by having cluster.example.com return  a set of IPs 
for all the riak nodes in the cluster, but that didn’t help either. In the 
perfect world, this should.

Thanks to Alex, Zeeshan, and Sean for helping out on IRC.

Just to add to this, seems like even after waiting for 15 mins, the start 
script fails because it is unable to ping the node. Tracing through the 
scripts, we arrive at the nodetool in /usr/lib/riak/erts-5.10.3/bin  which is 
calling {net_kernel:hidden_connect_node(TargetNode), net_adm:ping(TargetNode)} 
to check the status of the node and is getting {_, pang} in return. Results in 
printing out "Node 
'ria...@riak.prod.pryvy.com' not responding 
to pings." At this stage riak console is still unable to connect and still 
nothing in error or crash logs.  Any hints on how to proceed, or ways to 
collect more debug info appreciated.

Hi there,

Building out a new cluster (for the first time) and package cloud pushed down 
2.1.0-1. I have gone through and installed all the necessary packages, 
configured riak through riak.conf and attempting to start the first node in the 
cluster. Unfortunately, even though the processes are running, riak-admin 
reports that no nodes are running.

The config states that it should be listening on:

listener.http.internal = 127.0.0.1:8098
##listener.protobuf.internal = 10.IP.IP.IP:8087
listener.protobuf.internal = 127.0.0.1:8087

I initially had it listening to our internal network IP, but as part of 
testing, switched to localhost to see if it resolves it but alas, that’s not 
the case.

In the log directory, files crash.log and error.log are empty and the 
console.log reports things are ok:
