Hi,
We've had a discussion internally to start to run `nodetool verify`
periodically to test for bitrot. Does anyone know how I could check if the
verification failed or succeeded from, say, a script? Is there an error
exit code or some output I could grep for?
Thanks,

Hi,
I am considering tuning the tombstone warn/error threshold.
Just making sure; If I INSERT one (CQL) row populating all six columns and
then DELETE the inserted row, will Cassandra write 1 range tombstone or
seven tombstones (one per columns plus row marker)?
Thanks,
Jens
a row tomstone and not one tombstone per column, fortunately

Hi,
Does this have anything to do with Cassandra? Also, please try to avoid cross
posting; It makes it hard for
- future readers to read the full thread.
- anyone to follow the full thread.
- anyone to respond. I assume there are few who are enrolled to both mailing
lists at the same time.
the status of that.
2 - `nodetool status` is your friend. It will tell you whether the cluster
considers other nodes reachable or not. Run it on a node in the datacenter that
you’d like to test connectivity from.
Cheers,
Jens

Hi again,
A follow-up question (to my yet unanswered question):
How come the first localDeletion is Integer.MAX_VALUE above? Should it be?

in system.log. My primary key is ((userid uuid), id uuid). Is it possible
for me to see from this output which partition key and/or ranges that has
all of these tombstones?
Thanks,

it depends on many factors but I'd like to
hear an experienced estimation): How much time would take to rebuild a 250G
data node?
Thanks in advance,
Or.

alternatives here?
In the best of worlds, the fetchSize property would also honour the number of
tombstones, but I don’t think that would be possible, right?

For the first row, the key is: (2014, N, 1, සියළුම, යුද්ධ) and the value-part
is (664).

Maybe checking which thread(s) would hint what's going on? (see

Hi Robert ,
Maybe you need to flush your memtables to actually see the disk usage increase?
This applies to both hosts.

improvements would obviously be to not hardcode `us:` and support the
other histograms. Also, this logic should maybe even be moved into the
`nodetool cfhistogram` since these are fairly common metrics for latency.

Maybe slightly off-topic, but what is a mutation? Is it equivalent to a CQL
row? Or maybe a column in a row? Does include tombstones within the selected
range?
Thanks,

Hi,
I don’t know if this is “best practice”, but you could do this using mocking if
nothing else.

uploading.

. Make sure to pipe the output to a file
or the `syslog` utility.
* It does not do continuous/point-in-time backup.
That said, it does its job for us for now.
Feel free to propose improvements!

Truncate does trigger snapshot creation though
Doesn’t it? With “auto_snapshot: true” it should.

and system.schema_columns, but as always
reusing a proven tool would be preferable.
So far I only know of Spring Data Cassandra that handles creating tables and
adding columns. However, it does not handle table properties in any way.

Hi Dmitri,
I have not used the CPP driver, but maybe you have forgotten set the equivalent
of the Iava driver's fetchsize to something sensible?
Just an idea,
Jens
