Re: Decommission faster than bootstrap

Do you think that not to run cleanup operation after bootstrapping a node can affect the bootstrap time of a subsequent node? I mean, keys not removed can somehow affect a bootstrap operation? Thanks. Att. *Rodrigo Felix de Almeida* LSBD - Universidade Federal do CearĂ¡ Project Manager MBA, CSM, C

Boris, We are not using secondary index. We tested both on version 1.1.5 and 1.1.12 and had similar results. Does anybody know what are the steps in details to bootstrap and to decommission a node? I'd like to figure out which step is creating this difference. For me, the time should be simila

We are using 1.0. Our observation is that if you are using secondary index, building secondary index after streaming is time consuming. And the bootstrap needs to wait for the process of building secondary indexes to complete. I am not sure if this also applies to 1.1/1.2. You could set the log le

We've also noticed fairly poor streaming performance during a bootstrap operation, albeit with 1.2.x. Streaming takes much longer than the physical hardware capacity, even with the limits set high or off: https://issues.apache.org/jira/browse/CASSANDRA-5726 On Sun, Aug 18, 2013 at 6:19 PM, Rodrig

Decommission faster than bootstrap

Hi, I've noticed that, at least in my enviroment (Cassandra 1.1.12 running on Amazon EC2), decommission operations take about 3-4 minutes while bootstrap can take more than 20 minutes. What is the reason to have this time difference? For both operations, what it is time-consuming the data st
