No you are wrong php thrift implementation doesn't use sock extension it
uses
I'd also be quite interested in some qualifications on that Hector

if you have anything specific.

Hi,
I was just about to upgrade to the latest 0.8.x, but noticed that
there's no RPM package for 0.8.9 on DataStax repo. Latest is 0.8.8.
Any plans to publish 0.8.9 rpm?

No php client doesn have TCP_NODELAY, becaus
Should already be on for all of the server side stuff. All of the
clients that I have used set it as well.

Hello
Is it possible set TCP_NODELAY on thrift socket in cassandra?
Outgoing TCP connections between nodes have TCP_NODELAY on, so do server side
THRIFT sockets.
I would assume your client will be setting it as well.

Yes it is.
But it depends on what you want to select.
Cassandra does not have a complete query language like SQL in an RDBMS. You
need to design your data model to support the queries you wish to make.
Normally this means denormlising data so that queries are essentially reading
from a materi

Sorry but you misunderstand me, is ask is cassandra have any option to
control TCP_NODELAY behaviour, so we doesn't need patch cassandra or thrift
code.
I found this article
https://wiki.cs.columbia.edu:8443/pages/viewpage.action?pageId=12585536,
where упоминается mentioned coreTransport.TcpClien
Can you elaborate on the composite types instabilities ? is this
specific to hector as the radim's posts suggests ?
These one liner answers are quite stressful :)

Could you please provide this way for linux?, for particular application?
Maybe some sysctl?

We may have 10k versions in some cases, with up to a million names
total in any given version but more often <10K. To man

It's always darkest just before you are eaten by a grue.
This is on single node environment, and there is a lot of data in commit logs
needs to be flushed to sstables. So remove commit logs will cause data lost.
Fortunately, this issue happens on a new key space that have CFs that use
composite type, and we can sacrifice loosing data on this new key spa
Caches might be it. Will try reducing and see how it goes.
Didn't mention this because I wasn't seeing the same errors yesterday, but last
night thought it might be worth mentioning.
Had changed the location of some data last week, a few days subsequent to that

That's once in few days, so I don't think it's too important. Especially
since 0.77 is much better than 0.99 I've seen sometimes :)

I'm not in production yet. As exercise, stopped all nodes when this error
occurred and I could not start any node again.
If you need to use composite types and create/drop column families on the
fly you must be prepared to instabilities.
why would you ever want to stop all nodes together?

I found out this is related to schema change. Happens *every time* I create
drop and new CF with composite types. As workaround I:
* never stop all nodes together
To stop a node:
* repair and compact a node before stopping it
* stop and start it again
* if it started fine good if not, remove all
Hi,

I used to have rpc_address set to 0.0.0.0 to bind cassandra to all
interfaces. After upgrading out Hadoop jobs to cassandra 0.8.9 (from
0.8.7) there are lots of these messages, and the jobs fails.
