Hi, Riak uses a logging library called lager that traps the output from SASL logging, so you should not need to set anything up. You can either apply the lager parse transform to your commit hook code and then you should be able to use lager:error/2, lager:warning/2, lager:info/2 to write to the

Re: riak 2.1.1 : Erlang crash dump

It looks like Riak was unable to allocate 4Gb of memory. You may have to reduce the amount of memory allocated for leveldb from the default 70%, try setting this in your /etc/riak/riak.conf file leveldb.maximum_memory.percent = 50 The memory footprint for Riak should stabilize after a few hours

Re: "Accumulator" convergent data type

Conceptually I think it should work - the same PN counter design could handle floats as well as integers. You'd have to make sure the P and N values only grew by handling the sign - if you want to add a negative float you would do N += abs(V). There are also concerns around error bounds and all th

Re: Node join not committed

Hi Daniel, It's perfectly safe to issue the cluster plan/commit steps. Joining the node gives it information about where data is located in the rest of the cluster and it will happily coordinate gets, but the new node will always forward put requests and will not store any data until you go throu

Re: Ownership handoff timed out

Hi, I suspect your {error,enotconn} messages are unrelated - that's likely to be caused by an HTTP client closing the connection while Riak looks up some networking information about the requestor. The max_concurrency message you are seeing is related to the handoff transfer limit - it should be

Re: Pre-commit hook debug

Hi Geoff, Looks like the WM endpoint isn't handling that crash well. As for your precommit hook, the hook runs inside the server context so you'll need to use the riak_object module instead. riakc_obj is a cut-down version for use in the Erlang client. Jon On Tue, Dec 1, 2015 at 11:53 AM Geoff

Re: Riak pre-commit hook crashing unexpectedly

Does your signed_pb:decode_sign(Msg) function expect the binary to be in external term format? I would guess you probably want the direct value there without the term to binary - it should already be a binary. Is your hook expected to work with allow_mult=true, if so the get_metadata and get_val

Re: Core Claim and Property-Based Tests

Thanks for the excellent writeup. I have a few notes on your writeup and then a little history to help explain the motivation for the v3 work. The Claiming Problem One other property of the broader claim algorithm + claimant + handoff manager group of processes that's worth mentioning is saf

Re: Using protobuf client in Java

Hi Matthew, When you read the serverInfoResp you need to read the header to find the length of the response message. The header is 5-bytes - 4-bytes of length and 1-byte of message code. You should just use the parseFrom calls - not the parseFromDelimited ones. Please excuse my java - I have

Re: Protocol buffer Vs BERT

Hi, For the first part - we used protocol buffers because we had requests for a PB interface from customers and as developers we have more experience using it on other projects. For the second part - I would recommend using the PB interface. It has about the same performance as riak_client

Re: Riak Erlang Client

Hi Dan, You're right - the documentation is woefully lacking. We'll try and improve it soon, the protocol itself has an entry on the wiki, but each of the clients need some too. For now your best best is to look at the unit tests at the end of riakc_pb_socket - that'll show you how you can

Re: Protobufs & HTTP

Hi Eric, For the HTTP interface to work correctly you need to supply a content type when you do your updated - if you add something like request.content.content_type = 'application/json' Then you should be in business. The python client at http://bitbucket.org/basho/riak-python-client i

Re: Help with protobuf (again)

Hi Matthew, The client ids used for get/set client ids are supposed to be opaque - at the moment they're 32-bit integers but I didn't want to tie the interface to that. There were two use cases for the call - if you wanted to keep the same client id across reconnects you could call get client

Re: riak.py has been removed?

Hi Mark, The python client received a significant refactor today thanks to Silas Sewell. It is now more pythonic and can be installed with a setup.py file. riak.py got moved into riak/__init__.py as part of that. I'm not sure what bitbucket is up to, but a clean pull worked for me. Jon On

Re: CAP controls

Hi Jeremy, If it were me I would start off with the simplest set up possible - one riak node per physical machine. It'll be easier to see what is going on and reason about performance if there are less moving parts. For the storage configuration - if you are using innostore then keep one for

Hi Mikl, Thanks for the test case - it's definitely a bug in the PB client. I'll file a bug for you and work on a fix as soon as I have a chance. Jon On 5/26/10 5:45 AM, Mikl Kurkov wrote: Hi! It seems that protobuffers client doesn't allow to update metadata of object. Example: -module

Re: Memory Utilization

Hi Jason/Sean, I'll chime in on this one. Embedded Inno uses exactly the same transactional logging as it does under MySQL so it should recover in the same way without needing any user intervention. The tools Sean mentioned can be used in dire circumstances (e.g. log files got overrun or do

Re: Error Installing Erlang Client

Hi Ted, You should just need the riak-erlang-client/ebin and the protobuffs library. Here's an example on my local machine. I just checked the docs and there's a mistake in there. The module you can test to see if you have it all set up correctly is riakc_pb_socket. jons-macpro:systest jm
