spurious secondary index writes

[Damien Krotkine]

Hi,

On my cluster, I am using the Multi backend, with a bunch of bitcask
backends configured and a leveldb one. However, I am *never* writing to
the leveldb backend. And I'm never writing any 2i

However, riak-admin status is reporting secondary index writes:

sudo riak-admin status | grep index

index_fsm_active : 0
index_fsm_create : 0
index_fsm_create_error : 0
vnode_index_deletes : 0
vnode_index_deletes_postings : 0
vnode_index_deletes_postings_total : 0
vnode_index_deletes_total : 0
vnode_index_reads : 0
vnode_index_reads_total : 0
vnode_index_refreshes : 0
vnode_index_refreshes_total : 0
vnode_index_writes : 3484
vnode_index_writes_postings : 0
vnode_index_writes_postings_total : 0
vnode_index_writes_total : 67341668


I don't understand how this can happen. Is Riak using secondary indexes
internally, or is the metric being polluted byt other values ? I ned to
make sure my cluster is not creating secondary indexes :)

Thanks,
Damien Krotkine

An outbound handoff of partition error enotconn

[changmao wang]

Hi Riak-users,

I have found some errors related to handoff of partition in
/etc/riak/log/errors.

I have searched it with google and found related articles. However, there's
no solution.

Selective indexing of Riak Data Types

[Marius Cobzarenco]

Hi all,

I was curios if there's a way to enable Solr indexing on only some of the
fields of a Riak CRDT Map (not all of them). E.g. for a map:
[{"field_1", "register"}, {"field_2", "register"}] I would like to _only_
create the Solar index field_1_register .

By default if I enable search on a bucket with maps, Riak creates Solr
indexes for all fields in the map.
https://docs.basho.com/riak/latest/dev/search/search-data-types/

Many thanks,
Marius

Re: Selective indexing of Riak Data Types

Hello Marius, 

Yes, you can by just specifying those fields in the schema, e.g. 
field_1_register. For example, I created similar fields in this test (using a 
custom schema, inlined): 
https://github.com/basho/riak_test/pull/800/files#diff-ab08303805d0b8fe5d7fe683273b2fbfR75
 
,
 and then set them in the map like so: 
https://github.com/basho/riak_test/pull/800/files#diff-ab08303805d0b8fe5d7fe683273b2fbfR178
 
.
 Obviously, you then don’t need the default, embedded dynamic *_register fields 
and such, which captures all of them.

Hope that helps!

Hi Zeeshan,

It makes sense, thanks loads for the pointer & code examples, it's exactly
what I was looking for.

Cheers,

Riak CS Node Shutdown Because it Ran Out Data Space - Unbalanced With Other Nodes in Cluster

[Valenti, Anthony]

We have a Riak CS node that ran out of space on the data mount and the service 
shutdown.  This is strange since the other nodes in the cluster seem to be 
about 76%-78% full.  Why is it so out of balance and how can it be fixed?

Riak Recap - July 31, 2015

[Matthew Brender]

Hey everyone! As always, there's been some great knowledge sharing over the
user lists. Here is your biweekly Recap!

Note that many of the "unanswered" are brand new and I know we'll get to
answering them. I just want you all to know we keep track of these.

## Announcements
* There's a new Java client in town! 2.0.2 was released [0]

## Recently Answered
* Roman asks about using a FQDN and is guided to use 0.0.0.0 instead [1]
* The Riak C client ran into a segfault that Chris explained [2]
* Humberto found setting ulimit on OS X is a little tricky [3]
* I gave Sevilha some resources to spin up Riak locally [4]
* Zeeshan makes sense of indexing Riak Data Types for Marius [5]

## New and Unanswered
* Damien needs some help thinking through ring-resizing on a live cluster
[6]
* Sean gets an error while deleting an object through the Erlang client [7]
* Humberto could still use help with ulimit settings on OS X [8]
* Nick is helping Johan with a known Erlang bug in need of a patch [9]
* Damien sees 2i writes when he isn't using 2i. Any idea why? [10]
* Amao sees an outbound handoff error and still needs some help [11]

## All the Meetups!
We've been busy on the meetup scene, hosting events in Portland, Austin and
Chicago. If you'd like to see where groups are, we have a new URL to do so
[12]. Let me know if you'd like to run one in your city!

## What'd we miss?
Have you brought Riak into production at a new place? Did you find a blog
or presentation helpful? Good! Share it in our release notes:
https://github.com/basho-labs/the-riak-community/tree/master/release-notes

Have a great weekend,
