Hi,
is there any way to determine that rebuild is complete
If you ran it from a screen (
https://www.gnu.org/software/screen/manual/screen.html) or similar stuff,
you should see the command return.
Also, 'nodetool netstats | grep -v 100%' will show you remaining stream.
No stream = rebuild fin
Hi Joe,

I have been working alone 4 years operating a growing cluster (from 3 to

Hi ,
We have the data dump into directory taken from Mysql using the
CQLSSTableWriter.
Our requirement is to read this data and load it into MySql. We don't want
to use Cassandra as it will lead to read traffic and this operation is just
for some validation .
Can anyone help us with the solutio
I am looking for way to optimize large reads.
I have seen using SSD is a good option but out of budget, so I am looking
for a way to use some kind of tiering with few SSD caching hot data from
HDD.
I have identified two solutions and would like to get opinions from you and

I'm not sure which driver you're referring to, but if it's the java driver,
it has its own mailing list that may be more helpful:

We are using lvmcache for that.

Anishek,
AFAIK you can not have clusters "overlap" each oder.
Just an idea: Try to address it as an sstable restore.

What I would try to do (not tested!):
- create a logical DC in each cluster (
A, my bad. One might wonder why the heck the Java driver is "owned" by
an outside entity, eh?

Because it's a community driver not provided by the Apache project. There
have historically been community provided drivers in the past. See
Hector, Astyanax, pycassa, etc.

FWIW, the status quo prior to the Datastax drivers was a wide assortment of
non-compatible drivers in different languages, not one set of
But, if there were a Java driver provided by the Apache Cassandra project
itself, then it'd be an easy choice.

Can you provide me a approximate estimation of performance gain ?
