Hi Jonathan
Why would there be no data associated with the key? All I did was
restart the node while client threads were writing to the cluster. And
what kind of impact does this bug cause? I can't make any more
compactions on that node and I have to wipe out the data?
How does the trunk fix this
Thanks Chris.
Supercolumn may not be needed but since it's part of the API I need to work it
out - there is no application yet, I need to know what we can go with Cassandra
so that we can evaluate what we can migrate.
I will follow what you mentioned and see how far I can go.

Sure. But let me encourage you to think about your application. Most ones I
have ran into don't need supercolumns.
First you need to specify the column to be of the type super in the
storage-conf.xml file.
There are a few examples of that.
Then when you use the api to construct things called
The failing assertion is there to check that there actually is data
associated with the key.
Easiest fix to try is code from trunk.

Hi all:
I am using version 0.4.2 of Cassandra, and whenever I restart one of
the nodes only I am getting the following exception consistently:

I've only just got to looking at this again... which config file value are
you referring to here?
Chris.

lazyboy had a thread-based connection pool last time I checked, so he
should just have to thread his test loop for it to use multiple
connections. MySQL should suffer the same general problem though,
although I don't know the specifics of the MySQLdb module. Based on
his test, it's accurate to sa

This is your pr
Looking at

page 26
Cassandra should make around 100 read per sec
and around 10,000 writes per sec (on the data equivalent of a 50Gb
mysql db) so your results seem OK
How do your result
Hi Mark,
You need to build the project with ant, then add the generated class files to
your build path. Conversely, you can add the pre-built jar but then you'll end
up with namespace collisions with the source in your IDE. Eclipse *should* use
the source first, as long as you don't reorder t
Nо. But i think that all data will be in memory and gstat (FreeBSD utility)
show that no any disk activity.

Hi Ruslan,
did you store the logs and the data on 2 different disks as described at:

and
