* Running Cassandra outside of Intellij (starting the /bin/cassandra script)
Any help is really appreciated. Thanks!

Hi
Does anyone know what Cassandra uses WMI for when running on Windows? We have
some issues with high WMI CPU usage..
Yours sincerely / Med venlig hilsen

Hi all.
Having two FSReadErrors:
FSReadError in
..\..\data\system\compaction_history-b4dbb7b4dc493fb5b3bfce6e434832ca\system-compaction_history-ka-329-CompressionInfo.db
FSReadError in
Thanks for the advice.

Note for anyone who accidentally or otherwise ends up with 2.1.3 in a
situation they cannot downgrade, feel free to look at
https://github.com/vast-engineering/cassandra/tree/vast-cassandra
to just start the on 2.1.3 directly after 2.0.9.

So no upgradeSSTables are required?

I would not recommend an upgrade to 2.1.x for now. Do you have any specific
reason to upgrade?
For upgrading from 2.0.9 you can just do a direct upgrade.

1.0.5. But might there be problems/data incompatibility in the future when
upgrading Cassandra to a never version regarding *CompressionInfo.db files
etc..?
/Fredrik
Are there any official recomendations, validations/tests done with
Cassandra = 2.0 on Java 8?

Keeping your read 95th percentile low is mostly about removing deviations
that cause requests to slow down, swap is one of the things that cause
fluctuation becuase it is not predictable.

updating those user data properties
which might be spread out over many cf:s and many rows?
Regards
/Fredrik
I don't have a current use-case. I was just curious how applications
handle and how to think when modelling, since I guess denormalization
might increase the complexity of the application.
Fredrik
2013/1/27 Hiller, Dean dean.hil...@nrel.gov:
There is a really a mix of denormalization
to the backuped data.
What is the recomended way to handle this situation? Removing the hints
cf from the system tables before restart of the cluster nodes?
Regards
/Fredrik
I guess that the other nodes still gossips about the removed node. The
node isn't removed from gossiper in the cluster until some amount of
time have elapsed. My guess is that you haven't changed the cluster_name
property in the cassandra.yaml on the removed node.
Xu, Zaili skrev 2012-09-28
Wrong assumption of me. I found the answer in
GossipDigestSynVerbHandler. I forgot to change the cluster name of the
new cluster.

2012/9/11 Fredrik fredrik.l.stigb...@sitevision.se:
I've tested a scenario where I wanted to reuse a removed node in a new
cluster with same IP, maybe
change IP on the removed node if you want to use it
in another cluster?
Please enlight me.

Exactly, but why would reads be significantly slower over time when
including just one more, although sometimes large, SSTable in the read?
Ji Cheng skrev 2012-04-26 11:11:
I'm also quite interested in this question. Here's my understanding
while read performance will be good immediately following a major
compaction, it will continually degrade until the next major compaction
is manually invoked. For this reason, major compaction is NOT
recommended by DataStax.

may
result in reading multiple sstables for a single row key.
Please correct me if I am wrong.

In the tuning documentation regarding Cassandra, it's recomended

Yes, I'll do that.

You're right, good catch.
Do you mind opening a ticket on jira
(https://issues.apache.org/jira/browse/CASSANDRA)?

Hi
this be problem if we have
seldom updated column family that wont be compacted very often?
Is this considered a bug or is it something that won't be fixed due to
the way Windows handles hard links?

Does reading quorum mean only waiting for quorum respones or does it mean
quorum respones with same latest timestamp?
