Is there a way to re-use a prepared statement with different using
timestamp values?
BEGIN BATCH USING timestamp
INSERT INTO Foo (a,b,c) values (?,?,?)
...
APPLY BATCH;
Once bound or while binding the prepared statement to specific values, I'd
like to set the timestamp value.
Putting a question

Thanks Sylvain. I should have scanned Jira first. Glad to see it's on the
todo list.

Dear Community,
Could anyone please give me a hand with understanding what am I
missing while trying to model how LeveledCompactionStrategy works:

Logs mostly contain something like this:

1) Version is 1.2
2) DynamicComposites : I read somewhere that they are not recommended ?
3) Good point. I need to think about that one.

I would (kind of) agree with this point..
If you absolutely need performance here then python isn't the right

Thanks Aaron. I ran the cassandra-shuffle job and did a rebuild and compact on
each of the nodes.

Oracle already did this once, It was called jrockit :)

Typically oracle acquires they technology and then the bits are merged with
the standard JVM.

I've gotten timeouts on clients when using Cassandra 1.1.8 in a cluster of
12 nodes, but I don't see the same behavior when using Cassandra 1.0.10.
So, to do a controlled experiment, the following was tried:
1. Started with Cassandra 1.0.10. Built a database and ran our test tools
against it to

I have been struggling with the LCS myself. I observed that for the higher
level compaction,(from level 4 to 5) it involves much more SSTables than
compacting from lower level. One compaction could take an hour or more. By the
way, you set the your SSTable size to be 100M?
Thanks.

I may have found a trigger that is causing these problems. Anyone seen
these compaction problems in 1.1? I did run scrub on all my 1.0 data to
convert it to 1.1 and fix level-manifest problems before I started running
1.1.

Thanks Aaron, so will there only be one value for each counter column per
sstable just like regular columns?
Yes.
For some reason I was under the impression that Cassandra keeps a log of all
the increments not the actual value.
Not as far as I understand.

2) DynamicComposites : I read somewhere that they are not recommended ?
You probably wont need them.
Your current model will not sort message by the time they arrive in a day. The
sort order will be based on Message type and the message ID.
I'm assuming you want to order messages, so

Hi,
Has anyone used Netflix/astynax java client library for Cassandra? I have
used Hector before and would like to evaluate astynax. Not sure, how it is
accepted in Cassandra community. Any issues with it or advantagest? API
looks very clean and simple compare to Hector. Has anyone used it in
It's a really great library and definitely recommended by me and many who are
reading this.
And if you are just starting out on 1.2.1 with C* you might also want to
evaluate https://github.com/datastax/java-driver and the new binary protocol.
Best,

Astyanax is not working with Cassandra 1.2.1. Only java-driver is
working very well with both Cassandra 1.2 and 1.2.1.
