Will this stay like this or is it a release bug ?

Agree, EBS systems are not so good for cassandra systems and during previous
conversations in this mail list, people tend to use ephemeral.

Obviously ephemeral. It has higher IO availability, will not affect your
Ethernet IO performance, and it is free (included in instance price)
and the redundancy is provided by cassandra itself.

Well what client are you using? And can you give a hint to your node hardware?

Subject: Why is mutation stage
Someone has just talked about the heap size in this mail list, says that bigger
heap size will result into a longer GC phase, that could probably be one of the
reason not using larger heap size.
But I have really heard of some others using Cassandra with some 60 gigabytes
of heap size.

It is meaningless to release such memory. The counting includes the data you
reached in the SSTable. Those data locates on your hard drive. So it is not the
RAM spaces you have actually used.

I don't know if I understand correctly that UUIDs are good unless you have a
specific reading pattern. In the latter case you can develop a better
compound row key.

Which version are you using? In my memory 0.8.3 cannot do it correctly but
later versions fixed the bug.

I patched CASSANDRA 2530 on this version, and tested it for our financial

I'm trying to test a single issue:

But when I downloaded the patch file I can't find the correct trunk to patch...
Anyone can help me with it? Thanks

Sounds like it's a similar case as mine. The files are definitely, extremely
big, 10x space overhead should be a good case if you are just putting values
into it.
I'm currently testing CASSANDRA-674 and hopes the better SSTable can solve the
space overhead problem. Please follow my e-mail
BTW,
If I'm going to insert a SCF row with ~400 columns and ~50 subcolumns under
each column, how often should I do a mutation? per column or per row?

I wanna report my use case, and have a discussion with you guys.
I'm currently working on my second Cassandra project. I got into somehow a
unique use case: storing traditional, relational data set into Cassandra
datastore, it's a dataset of int and float numbers, no more strings,
additional coupling that's not needed .

Dear all,
I'm wondering what's the advantage of assigning column metadata when NOT using
secondary indices.
I've gone through the SSTable internal and found out it won't do such
conversion.Thus I think the only advantage we got via column metadata is a
data validation type, am I correct?

On possible solution is to decommission the disagree node and rejoin it.

Or has anyone started to work on it?
