I have been searching all over documentation but could not find an straight
answer.
For a project I'm using a single node cassandra database (so far)... It has
always worked well, but I'm reading everywhere that I should do a nodetool
repair at least every week, especially if I delete rows, which
what do you mean by "operating correctly" ?
I only use dynamic columns if that helps...

Don't think it is near failure, it uses only 3% of the CPU and 40% of the
RAM if that is what you meant.

I have a column family that store articles. I'll need to get those articles
from the most recent to the oldest, getting them from Country, and of
course the ability to limit the number of fetched articles.
I though about another ColumnFamily "ArticlesByDateAndCountry" with dynamic
columns

Hi everyone,
I need one more time your precious advice.
I would like to create a 2 nodes cluster, each node are on a different
DataCenter, but with the same provider, ping between the 2 servers is fast:
~0,5 ms, and the bandwidth is great: ~ 1GB/s
is, org.apache.cassandra.locator.SimpleStrategy w
However I guess it can be easily changed ? doesn' it ?

Thank you both for your precious advices !

Hi everyone,
I wanted to know if someone has a feedback using geoHash algorithme with
cassandra ?
I will have to create a "nearby" functionnality soon, and I really would
like to do it with cassandra for it's scalability, otherwise the smart
choice would be MongoDB apparently.
Is Cassandra can b
ing ready for geo-oriented interactions with C*; our plan is to

The news I guess would be to have it for free. I do not use commercial
versions. I wasn't aware of it though.
