I'm curious if there are any efforts ongoing to amortize the
background tasks in Cassandra over time?
Specifically, the cost of compaction and AE, rebalancing, etc seems to
be a problem for some users when they are expecting more steady-state
performance. While this may sometimes be the result of a

Are the restrictions on column family names specified anywhere? I see that
hyphens aren't allowed, and I assume anything else that wouldn't work in a
filename? I assume that underscores, commas, and periods are allowed?

We are using Cassandra 0.6.2 with hector/thrift client, and our
application performance is really slow. We are not sure that it is
because of hector/thrift connection or not. Jonathan E. and other
people has suggested that using "TBuffferedTransport(TSocket) instead of
a TSocket directly" perform
When I gave a presentation on cassandra+hadoop, some ruby folks were wondering
about the possibility of using the MapReduce functionality in a language other
than Java.
I was just wondering if any thought was given to exposing the
org.apache.cassandra.hadoop functionality through thrift. That
exposing it through thrift would mean the path would be
client
to cassandra [processing thrift command]
to hadoop [giving it a job]
to cassandra [fetching the data]
to hadoop [m/r]
to cassandra [handing result back]
to client
it just doesn't seem like a good design to me.
additionally, thrift is
Java transports buffer internally. there is no TBufferedTransport the
way there is in C#.

I just didn't know if there were any way to make it easier for the non-java
crowd to take advantage of it. I'll give it some more thought.

In theory ,it could do some help.
