Cool. Thanks. That should be easy enough to fix :-) On Mon, Apr 2, 2012 at 8:05 AM, Sylvain Lebresne wrote: > There's an open issue for that: > https://issues.apache.org/jira/browse/CASSANDRA-3676 > Patch welcome :) > > -- > Sylvain > > On Sat, Mar 31, 2012

Compression on client side vs server side

Hi, I was curious if I compress my data on the client side with Snappy whether there's any difference between doing that and doing it on the server side? The wiki said that compression works best where each row has the same columns. Does this mean the compression will be more efficient on the se

Is the wiki outdated regarding Hive support?

The wiki says "Hive support is currently a standalone project but will become part of the main Cassandra source tree in the future. See https://github.com/riptano/hivefor details." This seems outdated to me since Datastax isn't planning any future u

Ok, got that figured out. That was my fault. Though I'd suggest deleting that method instead of having it be a no-op. The missing Maven deps still seem like a bug though. On Sat, Mar 31, 2012 at 12:26 PM, Ben McCann wrote: > Also, I had to add the Yammer metrics dependency to get th

Re: [BETA RELEASE] Apache Cassandra 1.1.0-beta2 released

I'm trying to upgrade Solandra to use 1.1.0-beta2 and think I found a minor issue: java.lang.NoClassDefFoundError: edu/stanford/ppl/concurrent/SnapTreeMap at org.apache.cassandra.db.AtomicSortedColumns$Holder.(AtomicSortedColumns.java:296) Looks like this dependency is missing from cassandra-all-1

Re: create column family

I think the confusion here is that cassandra-cli and cqlsh have different syntaxes. On Fri, Mar 30, 2012 at 4:37 PM, aaron morton wrote: > Background: > http://www.datastax.com/docs/1.0/references/cql/CREATE_COLUMNFAMILY > > What error are you getting ? This works for me. > > cqlsh> use dev; > c

Re: How to store a list of values?

I was given one other suggestion (which may have been suggested earlier in this thread, but is clearer to me with an example). The suggestion was to use composite columns and have the first part of the key name be "skill" and the second part be the specific skill and then store a null value. I ho

I have a profile column family and want to store a list of skills in each profile. In BigTable I could store a Protocol Bufferwith a repeated field, but I'm not sure how this is typically accomplished in Cassandra. One option would b

Hmmm, I don't see anything regarding column families in cassandra.yaml. It seems like the answer for that question in the FAQ is very outdated. On Sun, Mar 25, 2012 at 4:04 PM, Serge Fonville wrote: > Hi, > > 2012/3/26 Ben McCann : > > There's a line that says "

Error in FAQ?

There's a line that says "Make necessary changes to your storage-conf.xml." I can't find this file. Does it still exist? If so, where should I look? I installed the packaged version of Cassandra available in the Datastax community edition.
