Cassandra 2.1.13: Using JOIN_RING=False

2017-05-09 Thread Anubhav Kale
Hello, With some inspiration from the Cassandra Summit talk from last year, we are trying to setup a cluster with coordinator-only nodes. We setup join_ring=false in env.sh, disabled auth in YAML and the nodes are able to start just fine. However, we're running into a few problems 1] The nodes

Hello, Recently, I started noticing an interesting pattern. When I execute "removenode", a subset of the nodes that now own the tokens result it in a CPU spike / disk activity, and sometimes SSTables on those nodes shoot up. After looking through the code, it appears to me that below function f

As someone not very familiar with core codebase, I just wanted to say that the comments on top of StreamSession class are a fantastic example of how comments should be. It helped me immensely to dig into node rebuilding code. So, thank you very much to the author of those comments. -Origina

DTCS Question

2016-03-19 Thread Anubhav Kale
Hello, I am trying to concretely understand how DTCS makes buckets and I am looking at the DateTieredCompactionStrategyTest.testGetBuckets method and played with some of the parameters to GetBuckets method call (Cassandra 2.1.12). I don't think I fully understand something there. Let me try to
