Look at the datastax documentation.

At first, I was also thinking that one or more nodes in the cluster are broken
or not responding. But through nodetool cfstats, it looks like all the nodes
are working as expected and pings gives me the expected inter-node latencies.
Also the scores calculated by dynamic snitch in the steady

further would be greatly appreciated.

of LOCAL_QUORUM operations is poor for a while (around a minute) after a

Late reply, but I just got the same error restarting after upgrading from
0.7.2 to 0.7.5.
I did a drain using nodetool on each node before I killed them and did the
upgrade. Should all commitlogs have been cleaned up after a drain? I would
think so, but they were not. Maybe there is a bug around
How large are your rows? binary_memtable_throughput_in_
mb only tracks size of data, but there is an overhead associated with each row
on the order of magnitude of a few KBs. If your row data sizes are really small
then the overhead dominates the memory usage and binary_memtable_throughput_in_
. To
understand your memtable row overhead size, you can do the above exercise with
very different data sizes.
Also, you probably know this, but when setting your memory usage ceiling or
heap size, make sure to leave a few hundred MBs for GC.

Hi, a node in my cassandra cluster will not accept keyspace additions applied
to other nodes. In its logs, it says:
DEBUG [MigrationStage:1] 2011-02-15 15:39:57,995
DefinitionsUpdateResponseVerbHandler.java (line 71) Applying AddKeyspace from
{X}
DEBUG [MigrationStage:1] 2011-02-15
So if Key A is supposed to go to Node, 1,2,3 then the commit log for Key A
will be on each of these nodes?
There isn't a commit log per key, just one for each node tracking what's been
written to that node. If a node1 determines node2 or node3 should handle a
request it received, it'll route
unsubscribe
when a request comes in which node handles the request first
You (ie. cassandra client) always specifies the exact node to send requests to.
While most higher level clients let's you specify configurations for a whole
cluster, that's usually for their own basic load balancing. Each request any
Each row can have a maximum of 2 billion columns, which a logging system will
probably hit eventually.
More importantly, you'll only have 1 row per set of system logs. Every row is
stored on the same machine(s), which you means you'll definitely not be able to
distribute your load very well.
for that?
