Please, don't mail me directly

I read your answer, but I cannot help anymore

And answering with "Sorry, I can't help" is pointless :)

Wait for the community to answer

Objet : Re: cassandra scalability

when there's a scaledown action, i make sure to decommission the node before. but still, I
don't understand why I'm having this behaviour. is it normal. what do you do normally to remove
a node? is it related to tokens? i'm affecting to each of my node a different token based
on there ip address (the token is A+B+C+D and the ip is A.B.C.D)

the result of the query select * from service_dictionary.table1; gave me
 70 rows from 40.0.0.205
64 from 40.0.0.209
54 from 40.0.0.208
