riak reached_max_restart_intensity

[Jorge Garrido]

Hi

An error has been detected in riak, the error is:

reached_max_restart_intensity

the problem I think is the ulimit in the system used by riak because when I
try make a put to riak with a large content the node is disconnected from my 
application, but I am not sure of that

I use protbuffs to access riak, using a simple load balancing to my cluster.

Is it the problem?
How can I configure the ulimit for riak, if it is the problem?

Thanks

Jorge Garrido

[Jorge Garrido]

Hi

Actually we are usign riak in production, but we are worried for the size of our
backups, actually the size is 5 GB, is that normally or can we implement any 
solution for that??

Thanks

{error, <<"timeout">>}

[Jorge Garrido]

Hi

Recently I have had some problems in my cluster on Riak, when I make a put on a 
node, 
Riak sends {error, <<"timeout">>}, I dont know which is the cause, all nodes in 
the cluster
are agree.
I use protobuffs to connect erlang client application to Riak, but when {error, 
<<"timeout">>} 
happens, my connection to riak node is down (disconnected).
Recently our servers are restarted but I dont know if it was the problem or the 
cluster
is not configured correctly, the main question is:

Which ones are the causes for this failure?

Thanks

Riak Search Using Riak Erlang Client

[Jorge Garrido]

Hi 

I've implemented a riak search using riak-erlang-client like this:

First I put an object into Riak using erlang:

$ erl -pa 

> ObjUser1 = riakc_obj:new(<<”users”>>, <<”user_one”>>, [{name, mario}, 
{age, 10}]).
  
  > riakc_pb_socket:put(Pid, ObjUser1).
  ok

Now when I try a search:

> riakc_pb_socket:search(Pid, <<"users_data">>, <<"name:mario">>).


it works, but if my object value is a proplist like this:

[{name, "MARIO"},.]

so, the values of each key in the proplist is a string

the question is: how can I make a query for this?

Thanks

Riak Search on Updated buckets

[Jorge Garrido]

Hi

Recently, i ve implemented riak search, but I am worried about a problem:

When data is written into riak (bucket), the riak search works great, but
when data is updated then riak search saves the old value and the new value for 
the 
search is not matching, 

can you tell me, what is it happening?

Issue on riak search when update bucket

[Jorge Garrido]

Hi, 

I 've a problem, when my application (written in erlang) puts data on a bucket 
that is installed with 'search-cmd install finder', data is working ok, and 
searchs is ok.

The problems comes when update data, then when my application search, Riak 
retrieves the data matching the old value and the new value

How can I kept only last value (updated) for Riak search? 

Thanks

Bitcask .write.lock and bad behaviours

[Jorge Garrido]

Hi, 

In the last weeks we are experimenting a bad behaviour in our riak cluster, the 
bitcask backend is creating .write.lock files and it is related to bad 
behaviours when we are accesing to data, for example mapreduce, links or even 
write, update or get data from/to cluster.

The solution that we found is delete all .lock files, but we know if there any 
option to prevent this or if this is a issue on riak?

We use riak version 1.2.1 and we check the logs but we don't get any info about 
this problem.

Any ideas?

Thanks

Riak 2.0 override default schema

[Jorge Garrido gomez]

Hello,

We migrate our data from Legacy to Riak 2.0, the migration was success, but we 
use the default schema provided by Riak, 

The question is: If we assign a new schema to the indexed bucket, it works in 
the same way or data could be corrupted and queries will throw any error?

Thank you

Delete Objects SOLR

Hello, 

On riak version 1.x when the search indexes are deleted then the data base is 
corrupted, is the issue present on riak 2.x with YOKOZUNA and SOLR?

The question is because we want delete the objects indexed into Riak Search 2.0

Re: Error on crash.log

[Jorge Garrido gomez]

Hello,

Recently we upgrade our core application written in erlang that uses riak 
erlang client with protobuffs, before this upgrade we use a simple load 
balancer between nodes, so in a simple gen_server a pid is created and keep 
into the state, but some times the pid will be disconnected and we must connect 
again.

So for that reason we decide use other strategy, we fork the project 
riak-erlang-client and decide to make a small change, we add in the options of 
the start_link function (where pid is created) a new option called: 
mod_callback, with this we send back the response of the pid, so the callback 
module knows that a pid was created and then added to the load balancer, all 
pids are managed by a supervisor, so when a problem occurs the supervisor 
restart a child and then the option mod_callback notifies to our load balancer 
so we can keep it into the state.

This change is here: 
https://github.com/zgbjgg/riak-erlang-client/commit/a531cd98cbaf119becc6c85091b2242cb08cbc0a
 


If you consider that this commit will be into your main repo, we can open a 
pull request, 

Than you very much!
