Re: Cassandra Configuration VS Static IPs.

Basically your client just needs a route to talk to the IP being broadcast by each node. We do plenty in EC2 and we use the instance private IP in the broadcast address. If you are doing multi-datacenter in EC2 it gets a little harrier, where you need to use the public IP (but not necessarily ela

Re: Changing schema on multiple nodes while they are isolated

Clint Martin's idea of each node creating its own keyspace, but then deciding which to use depending on the state of the cluster is really interesting. I am going to explore that in more detail. Thanks for the good idea. On 3 October 2015 at 00:03, Clint Martin < clintlmar...@coolfiretechnologies

Re: Example of JavaBeanColumnMapper

Hi Ashish, The components you mention are not part of the Java driver but belong to the Spark Cassandra Connector project , so I guess you will have more comprehensive answers by asking your question on the project's dedicated mailing list

RE: Changing schema on multiple nodes while they are isolated

Then maybe Cassandra is not the right tool for that, or you need a different data structure. For example you could keep a single table where what used to be your table name is now a part of you partition key. That way any “offline” data will be merged when the nodes join again. If you have confl

G1GC still has an Eden size, however, it's strongly recommended *NOT* to set the new gen size G1GC and just let it figure it out based on your target pause time. Thanks, Daniel On Sun, Oct 4, 2015 at 4:11 PM, Tushar Agrawal wrote: > If you are using CMS garbage collector then you still have to

Strange behavior of timestamp column

Hi all, we have a very simple cassandra table that contains just a single row. We have a 3-machine cluster using Cassandra 2.1.8, cqlsh 5.0.1. I do the following: CREATE TABLE IF NOT EXISTS scheduler_config (name text, suspended boolean, modified_ts timestamp, last_scheduled_start_ts timestam
