Rebuild new DC nodes against new DC?

Hi list, We're bringing up a second DC, and following the procedure outlined here: http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html We have three nodes in the new DC that are members of the cluster and indicate that they are running normally. We have beg

future very wide row support

Hi, My understanding is that wide row support (i.e. many columns/CQL-rows/cells per partition key) has gotten much better in the past few years; even though the theoretical of 2 billion has been much higher than practical for a long time, it seems like now Cassandra is able to handle these better

Adding New Nodes/Data Center to an existing Cluster.

Here is the situation. We have 3 nodes in Data Center A with Replication Factor of 2. We want to add 3 more nodes in Data Center B with Replication Factor of 2. Each node in Data Center A has about 150GB of data. When we add 3 more nodes in Data Center B, the repair tool starts syncing the data be

Cassandra 2.2 for time series

Hi I'm currently evaluating Cassandra as a potiantial database for storing time series data from lots of devices (IoT type of scenario). Currently we have a few thousand devices with X channels (measurements) that they report at different intervals (from 5 minutes and up). I've created as simpl
