Hi Peter
We try to figure that out how much data is coming in to cassandra once in
full operation mode
Reads are more depending on the hash values (the file name) for the binary
blobs - not the binary data itself
We will try to store hash values "grouped" (based on their first byte
(a-z,A-Z,0-9)
I want to point out my up hill battle tips.
Make some friends in the Freenode #Cassandra IRC channel.
Stop hunting for formal documentation and just read all articles and examples
you can get a hold if regardless of it is Java or PHP or Ruby.
Take a look at Thrift and it's many wrappers.

Hi Oleg, I didn't follow up the entire thread, but just to let you know that
the 0.6.* version of the CLI uses microsec as the time unit for timestamps.
Hector also uses micros to match that, however, previous versions of hector
(as well as the CLI) used milliseconds, not micro.
So if you're using
Just to clarify, microseconds may be used, but they provide the same
behavior as milliseconds if they aren't using a higher time resolution
underneath. In some cases, the microseconds are generated simply as
milliseconds * 1000, which doesn't actually fix any sequencing bugs.

Any insight is much appreciated..

Thank you guys for your help!
Yes, I am using System.currentTimeMillis() in my CRUD test. Even though I'm
still using it my tests now run as expected. I do not use cassandra-cli
anymore.
@Ran great job on Hector, I wish there was more documentation but I managed.
@Jonathan, what is the recommend
Oleg, note that the unofficial recommendation is to use microsec, not mili.
As jonathan notes, although there isn't a real way to get microsec in java,
at the very least you should take the mili and multiply it by 1000. If you
use hector then just use Keyspace.createTimestamp() (

That's a question that many Java developers would like the answer to.
Unfortunately, anything better than milliseconds requires JNI, since
the current JVM doesn't officially support anything higher. There are
solutions to this particular problem, but for most people,
milliseconds are sufficient out
