Gem versions?

A project I am working on uses the 1.0.0.beta2 versions of Ripple and Riak-Sessions. I have those gems installed and the code works fine. A colleague installed my project today (via bundler) but could not find the gems on rubygems. Did these gem versions get deprecated? What are the latest ve

Hi list, I have a bunch of random questions about the Erlang API that aren't quite answered by the documentation (at least from what I could find): * Is the proper way to replace the object associated with a bucket/key pair to simply do a riakc_pb_socket:put/2 with the same bucket/key pair (with

Jorge, Disks are fairly inexpensive these days, but if your production cluster is being hosted on another company's hardware, I can understand why you may be concerned. At the end of the day, either taking a filesystem snapshot or compressing riak's data directory are the most common backup proce

What will happen to the read when this occurs? - The read error is returned from the backend vnode to riak. Riak will still succeed if it can find valid data from the other nodes. Will this trigger a read repair when it happens? - Yes On Nov 26, 2012, at 2:29 PM, Paul Fisher wrote: > On

Alex, The eleveldb backend creates a CRC for every item placed on the disk. You can activate the test of the CRC on every read by adding: {verify_checksums, true}, to the "{eleveldb " portion of app.config. With riak 1.2, you must manually monitor each vnode directory for the lost/BLOCKS

Hi Jorge, Not sure I'm completely understanding your question here. Do you mean to say your data directory on each node is ~5 GB, and if so, are you worried about the cost of storage, time to transfer, or what exactly? Any more detail you can provide would be great. Thanks, Tom On Mon, Nov 26,
