Re: Storing Timestamps With Microsecond Resolution in RiakTS

Hi Joe, You could do that. Riak currently supports millisecond resolution. Look at the primary key composition. There are two lines, the first is the partition key and the second is the local key. The local key denotes the sort order and is the actual unique key for that grouping (quanta). You

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. Cheers Russell On 8 Dec 2016, at 21:19, John D

We have not done any work to support the multi-backend, hence the error you’re seeing. TS depends exclusively on leveldb. We’re not recommending the use of KV functionality in the TS product yet, because the latter is still changing rapidly and we will need to go back and fix some basic KV mech

Re: enotconn error

Travis - What are the client failures you are seeing? What Riak client library are you using, and are you using the PB or HTTP interface to Riak? The error message you provided indicates that the ping request returned from Riak after haproxy closed the socket for the request. One cause would be v

Re: Erlang client map reduce?

Hi Brandon - The riak_object module exports a type() function that will return the bucket type of an object in Riak (https://github.com/basho/riak_kv/blob/develop/src/riak_object.erl#L589-L592). MapReduce docs: http://docs.basho.com/riak/kv/2.1.4/developing/app-guide/advanced-mapreduce/ In addit

Re: Riak KV evolution

Thanks for your response Charlie! Riak KV is a great product, but as any other product it must evolve to keep ahead of its competitors. Glad to hear that improvements are coming :) On Tue, Oct 4, 2016 at 10:18 AM, Charlie Voiselle wrote: > Ricardo: > > Thank you for your question, and I want to

Re: Riak KV evolution

Ricardo: Thank you for your question, and I want to reassure you that Riak KV is still very much under active development. Work that is being done in the Riak TS codebase is being used to improve Riak KV where it applies. Riak KV 2.2 is coming soon and will include these new features: Global O

Hiya Alexander, Thanks much indeed for the detailed note... very interesting insights... As you deduced, I actually omitted some pieces from my email for the sake of simplicity. I'm actually leveraging a transient / stateless chat server (ejabberd) wherein messages get delivered on live sessions

Re: High number of Riak buckets

Hi Luke - many thanks... actually I was planning to have different bucket types have a different n_val. Or I might end up doing so... the thinking being that I intend to start my production workloads with fewer replications, but as the system matures / stabilizes (and also increases in userbase!),

Re: High number of Riak buckets

Hi Vikram, Bucket maximums aside, why are you modeling in this fashion? How will you retrieve individual keys if you don't know the time stamp in advance? Do you have a lookup somewhere else? Doable as lookup keys or crdts or other systems. Are you relying on listing all keys in a bucket? Defin

Re: High number of Riak buckets

Hi Vikram, If all of your buckets use the same bucket type with your custom n_val, there won't be a performance issue. Just be sure to set n_val on the bucket type, and that all buckets are part of that bucket type. http://docs.basho.com/riak/kv/2.1.4/developing/usage/bucket-types/ -- Luke Bakke

Re: Seeking Backup solution for live nodes

Neither. The leveldb instance creates a snapshot of the current files and generates a working MANIFEST to go with them. That means the snapshot is in “ready to run” condition. This is based upon hard links for the .sst table files. The user can then choose to copy that snapshot elsewhere, poi

there a backup tool that uses this yet? or is this meant more to be used with snapshots provided through xfs/zfs? On Monday, September 26, 2016, Matthew Von-Maszewski wrote: > Here are notes on the new hot backup: > > https://github.com/basho/leveldb/wiki/mv-hot-backup > > This sound like what y
