is there a = limitation of where reads/writes can go ie.,

reads= can go to all servers - seeds+nonseeds

writes can= go only to seeds

i think i get it

the other servers specify the seeds so = they join the cluster

I m lost here

Dont we need to specify atleast the server ip address in = =A0the conf file. How would cassandra know which ips they are running in ie= the other servers.

I can see there is a way to specify seed but how would the seeds= pick up the other servers if they do not know their ip address
<= br>
Also given the unlimited # of ips it cannot jus go thru each = one of the ips and ping 7001

Servers other than seeds are automatically picked up by th= e cluster when they start up; the nodes talk amongst themselves to figure o= ut who's there.

How do we add servers other than Seeds as there is no such place in conf fi= le

Servers other than seeds are automatica= lly picked up by the cluster when they start up; the nodes talk amongst the= mselves to figure out who's there.

Only the seeds need to be explicitly configured.

This is a Good = Thing :)
