Re: RiakCS poor s3 upload speeds 2MB/s

I found that adjusting these RiakCS settings improved write speeds a little for us: {put_concurrency, 4}, {put_buffer_factor, 8}, As well as making sure the Riak vm.args included a high +zdbbl setting. But even so, Riak CS has been really quite slow compared to other

Re: bitcask io mode

"The io_mode setting specifies which code module Bitcask should use for file access. The available settings are: erlang (default) — Writes are made via Erlang's built-in file API nif — Writes are made via direct calls to the POSIX C API" These sentences mention 'writes' only, does it affect other

bitcask io mode

Hi! Can anyone please explain in more details what kind of negative impact has the 'nif' bitcask IO mode and what worst-case scenarios can increase latencies or cause IO collapses? http://docs.basho.com/riak/latest/ops/advanced/backends/bitcask/#Configuring-Bitcask "In general, the nif IO mode p

Re: RiakCS poor s3 upload speeds 2MB/s

Hi David, At this point I'd like to recommend some tunings: * Change Bitcask to use "nif" I/O mode: http://docs.basho.com/riak/latest/ops/advanced/backends/bitcask/#Configuring-Bitcask * Use the following spreadsheet to calculate specific leveldb tunings for your environment. Let me know if you'

Hi Guido, Yes, you can run the 1.4.x java client against riak 2.0 as long as you don't activate the newer features like security and bucket types. Regards, Ciprian On Mon, Nov 10, 2014 at 2:58 PM, Guido Medina wrote: > Hi, > > Is it possible to run the Riak Java client 1.4.x against Riak 2.x?

Riak 2.x running with Riak Java client 1.4.x?

Hi, Is it possible to run the Riak Java client 1.4.x against Riak 2.x? At the moment we would have to do a major refactor in our application to support Riak Java client v2.x so I'm wondering if it is possible to first migrate to Riak v2.x before we start our refactor. Best regards, Guido.
