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?

AFAIK it's around 450G per ephemeral disk.
BTW randomly you can get high performance EBS drives as well. Performance are
good for DB but are random in IOps.

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.

you that 12G -16G is max to use.

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.

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

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.

@Jonathan:
I patched CASSANDRA 2530 on this version, and tested it for our financial
related case. It really improved a lot on disk consumption, using only 20% of
original space for financing-related data storage. The performance is better
than MySQL and also it consumes only 1x more than My
Thanks Jonathan, and thanks Peter.
How do u guys use the mail list? I'm using a mail client and this e-mail didn't
group up until i found it today...

Hi
I'm trying to test a single issue:
https://issues.apache.org/jira/browse/CASSANDRA-674
But when I downloaded the patch file I can't find the correct trunk to patch...
Anyone can help me with it? Thanks
Steve
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?

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 t

Dear all,
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, n

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?
Dear all,
I'm always meeting mp with schema disagree problems while trying to create a
column family like this, using cassandra-cli:
create column family sd
with column_type = 'Super'
and key_validation_class = 'UUIDType'
and comparator = 'LongType'
and subcomparator = 'UTF8Type
Is there anyone willing to upgrade the libcassandra for C++, to support new
features in 0.8.0?
Or has anyone started to work on it?
Thanks
