And after checking node who gc concurrentMarkSweep frequently ,it's OC(Current
old space capacity (KB)) is 1006016.0 ,it's OU(Old space utilization (KB).)
is also 1006016.0 ,almost all memory.
Dose this situation imply this heap size is set too low?
On Mon, Dec 6, 2010 at 8:07 PM,
I hava a two node , running cassandra ,both's memory is 4G.
First i set heap size to 2G ,both run normal .
The i set heap size to 1G , the client who insert data to and read data
from cassandra began throw Read\Write Unavailable Exception . And one
cassandra node began logging GC for ConcurrentM
x27;s
gc , intend to remove the unused file on harddisk ?

I'm using cassandra 0.7 .
And in storage-conf .
# The address to bind the Thrift RPC service to
rpc_address: localhost
# port for Thrift to listen on

In my client , the code below works successfully.

Hi all,
I don't know if anyone had post this question , if it is ,plz let
me know the post.
Here is the problem i met:
First , i create the keyspace that contains a columnfamily ,and
the columfamily contains a indexed column . The code is :
ColumnDef clDef = new ColumnDef("name
In dynamo's paper ,it says:
Each key, k, is assigned to a coordinator node .
The coordinator is in charge of the replication of the data items that fall
within its range.

Recently , i read the paper about Cassandra again .
And now i have some concepts about the reading and writing .
We all know Cassandra uses NWR ,
When read :
the request ---> a random node in Cassandra .This node acts as a proxy ,and
it routes the request.

,if we want to connect to the database , we must first do "TTransport tr =
new TSocket("localhost", 9160) " .
Then we operate on the database through this TTransport .
But this operation assigns a fixed IP , so all r
