For some reason I can not reply my old thread in that list. So I was creating a new one.
The problem is that I do not use thrift to gain in performace. Why it is nicer with concurrent modifications? I do not know why I have falling in the problem of concurrent modification if I was creating 2 keyspaces diferent in only one process with just one thread. Someone knows why? -- Everton Lima Aleixo Bacharel em Ciencia da Computação Universidade Federal de Goiás
