For #1 Storage Proxy (server wide) metrics are per request, so 1 in your
example. CF level metrics are per row, so 5 in your example.
Not sure what graph you were looking at in ops centre, probably best to ask on

Look in the logs for messages from the SecondaryIndexManager
starts with "Submitting index build of"
end with "Index build of"

If you create a reverse index on all column names, where the single row has a
key something like "the_index" and each column name is the column name that has
been used else where, you are approaching the "twitter global timeline anti
pattern"(™).
Basically you will end up with a hot row that h
You need to increase the JVM heap, cassandra picks sensible defaults if you
have enough server memory.
Reset all changed config files to default settings and make sure cassandra has
at least 4GB of JVM heap. The heap size is calculated in cassandra-env.sh.

After 2 days of endless compactions and streaming I had to stop this and
cancel shuffle. One of the nodes even complained that there's no free
disk space (grew from 30GB to 400GB). After all these problems number of
the moved tokens were less than 40 (out of 1280!).
Now, when nodes start they
I did try this option and everything is working fine. Thank you Aaron.

Hi,
I have a use case that sounds like storing data associated with files. So, I
store them with the CF:
rowkey = (folder_id, file_id)
colname = property name (about the file corresponding to file_id)
colvalue = property value
And I have CF for "manual" indexing:
rowkey = (folder_id, indexed val
Because cassandra is eventually consistent, and there are many settings
QUORUM, ONE, hint windows, disk failures, cosmic rays, node joins, there
are few absolutes.

So, you're saying that deleted rows can come back even if the node is always up
or down for less than max_hint_window_in_ms, right ?

Thanks Aaron.
We managed to sort out the Snappyjava issue by using snappy-java-1.1.0-M3.jar
available at http://code.google.com/p/snappy-java/downloads/list.
We are still facing issue with the below error when using Java 1.6.
