Hi,
Is there some utilities classes that we can use to store or retreive data
from Cassandra (like we have with spring-jdbc, spring-orm, spring-jpa, ...)
?
Can we compare Cassandra to Terracotta ?
Kind regards,

Thanks for the patch Sylvain! I remember during build Cassandra re-generates
the thrift java code (in src/) with a libthrift jar, is this correct?
Here's my use case:
1) Write/read ratio is close to 1:1
2) High volume of traffic and I want low read latency (e.g., 40ms). That's
why I'm testing
What will be the implications of the fact that cassandra can't keep up
with the write? Will the memtables be queued in memory until they are
flushed?

I used Terracotta on a previous project and you can think of it as a
persisted/fault tolerant cache.
The free version doesn't come with sharding, so your data has to fit on one
machine.
Other people I know have used it as a persistence layer (i.e.
Cassandra and Terracotta are distributed and can both store data,
but I think the similarities end there. My understanding of Terracotta
from recently evaluating their improvements to quartz is that their
design goals are more focused on distributed and fault tolerant JVM

Hey,
I have an application which is iterating over a directory with text
files in it. For each document it is ingesting words as keys, and the
docid as the column name with column value empty (no super columns).
Below is the code I'm using to construct a key and column:

Dear all,
My Cassandra data file (...-Data.db) have problem. I tried some ways
1. Use SstableExport: All row after error row can not be accessed. So with
large data file, I loss a lot of data.
2. Use Index file to get data position, and seek to this position in data
file to read data. All row
