Hi there,
I am trying to understand the underlying architecture of cassandra.
How does one node communicate with other node? Does cassandra use
Thrift or JMX to communicate with other node?
Kind regards,
Joshua.

Hi Aaron,
Does that mean the data will be deleted eventually? Does this also
depends on the compaction configuration?
Thanks.

Hi everyone,
Thank you to everyone that have responded to my email. I really

I think I understand now. The setRowCount() is in the Java Cassandra
driver. I'll try to find the similar method in the Ruby API.

Hi there.
It seems that when I fetch a range of rows, cassandra also includes
rows that has been deleted. Is it possible to only get rows that has
not been deleted?
Thanks for your help.
Kind regards,

NO it doesn't. Instead of using vector clock, it checks the column timestamps.

Hi,
Assuming the application does not know the list of keys that is stored

This list of row keys is going to be used to get a range of slices.

and Cassandra since
cassandra has ranges and build in secondary indexes whereas Riak does not.
Actually I use others too as the different ones bring different qualities to
the table.

Hi,
I am very puzzled with this. So I removed a row from the client, but
when I query the data from CLI, the rowkey is still there:
RowKey: 3

RowKey: 2
= (column=6e616d65, value=42696c6c, timestamp=1297338131027004)

RowKey: 1

Do you have loads of data? 1GB is quite reasonable knowing that 8GB is
the recommended RAM size

That makes more sense now. So I should instead find a way to (de)serialize

I really like the second index feature that has been added to 0.7 release.
My question is, Is it possible to query using wildcards in cassandra 0.7?
Thanks for the insights.

Hi there,
Quoting an information in the wiki about Cassandra limitations (
http://wiki.apache.org/cassandra/CassandraLimitations):
... So all the data from a given columnfamily/key pair had to fit in memory,
or 2GB ...
Does this mean
1. A ColumnFamily can only be 2GB of data
2. A Column

On the same box or a different box?
