1). set commitlog sync in batch mode and the sync batch window in 0 ms
2). one client wrote random keys in infinite loop with consistency level

Amrita,
I recommend you to take a bit more time to investigate, think, and
struggle on the problems by yourself before posting questions.
It will increase your technical skill, and help you much when you will
face on really serious problem in future.
For the current problem, if I am you, I'll

Hi all
now that JRockit is available for free and the claims are there that it has
better performance and gc I wanted to know if anybody out here has done any
testing / benchmarking yet.
Also interested in deterministic gc ... maybe its worth the 300 bucks?
Cheers,

Subject: Re: Appending to fields
Sounds like Ed is right and you should be doing the append as
add-a-new-column instead of
Well, my information is old...
But back in the heyday of VMs, JRockit really only had one specific
area of performance advantage, which was in message passing, and all
their benchmarks were tweaked to play to that.
Id say its not coincidence that oracle has made this free shortly
after they
Cassandra handles this by using a different design, you don't append
anything. You use the fact that in Cassandra you have dynamic columns
and you make a new column every time you want to put more data in. Then
when you do finally need to read the data out you read out a slice of
columns, not

isn't super obvious to me at the moment...

A $35 book was published today with a really excellent chapter describing of
the NoSQL ecosystem. If you’re interested in the NoSQL space, I highly
recommend it (and you can read it for free from the links below):
NoSQL Chapter: http://www.aosabook.org/en/nosql.html
Rest of book:
The best thing to do is log into jira and vote for the feature so others know
people are interested in it.

e.g. Using a the SimplePlacementStrategy, with the nodes ordered 0 to 9 and CL
