maintained by Eric Evans and the init.d script stops the server correctly.

The iostat numbers are rather low as is cpu utilization. We have a couple
of nightly jobs which do a lot of reads in a short amount of time. That is
when the pending reads was climbing. I'm going to bump up the number and
see how things run.

it couldn't keep up with new writes. In the end, I completely dropped that
server and spun up another one to take it's place since the one good server
had all the data anyway. So, it might have also been an issue with that
box.
One more question, are all of the instances in the same region?

Also, I am using batch_mutate for all of my writes.

You need to set the Reversed attribute on the sliceRange. I don't know
which library you are using, but it may be something like
sliceRange.setReversed(true).

Thanks. I'll apply the patch. I'm not real familiar with the JVM options,

It is not an ideal solution because the timestamp you pass in may not have
the same granularity as the one used to create your current indexes. So,
you might be using a standard unix epoch timestamp in seconds, while a true
TimeUUID uses 100 nanosecond slices of time.

cassandra couldn't recover from the error because I didn't have enough
memory on the machines. I have now upgraded to larger machines and that has
cleared up the real memory issues.

When I am verifying the columns in the mutation map before sending it to
cassandra, none of the timestamps are 0. I have had a difficult time
recreating the error in a controlled environment so I can see the mutation
map that was actually sent.

to feel like this is a bug in Thrift or the Cassandra Thrift interface. Can
anyone offer any other insight? I'm using the current stable release of
Thrift 0.2.0, and Cassandra 0.6.0.
It seems to happen more under heavy load. I don't know if that is meaningful
or not.

Has anyone used json2sstable to migrate a large amount of data into
cassandra? What was your methodology? I assume that this will be much
faster than stepping through my data and doing writes via PHP/Thrift.
Lee Parker
It appears that after some testing, the buffered transport seems more
stable. I am occasionally getting a missing timestamp error during
batch_mutate calls. It happens both on framed and buffered transports, but
when it happens on a framed transport, the server crashes. Is this typical?
Lee
nevermind. I figured out what the problem was. I was not putting the
column inside a ColumnOrSuperColumn container.
