Hello George,
You can use sstable2json to create the json of your keyspace and then load
this json to your keyspace in new cluster using json2sstable utility.

There is no resume in versions before 2.2.x, it will duplicate-rebuild

IIRC it does no

Rob,
It is inevitable that the repairs are needed to keep consistency guarantees. Is
it worthwhile to consider RAID-0 as we get more storage? One can treat loss of
disk as loss of node and rebuild the node and repair. Any other suggestions are
most welcome.

Hello Boying,
1. "repairedAt" actually means "fullRepair", so set that to true if you
want to run ordinary/full repair or false if you want to run incremental
repair.
2. You should use StorageServiceMBean.repairAsync(String, Map), where the options map will be parsed by
org.apache.cassandra.repair
Honestly 20ms for spinning disks is really good, so I think you're just
dealing with the reality of having a certain percentage of your reads off
disk and not in memory. If you're reading data that is on older SSTables
and you're out of buffer cache I'm not sure how else you could improve that.
So
Hi, All,
We plan to upgrade Cassandra from 2.0.17 to the latest release 2.2.3 in our
product.
We use:
/**
* Same as forceRepairAsync, but handles a specified range
*/
public int forceRepairRangeAsync(String beginToken, String endToken, final
String keyspaceName, boolean isSequential,
14 matches
