The N replication factor determines reliability of the data. If you have N=1, losing one node of the cluster means you have DEFINITELY lost data. On the other hand, the value of raising N diminishes iteratively and begins to waste resources. So it depends: if you don't care about losing data (e.g. if you can just replace the missing documents), lower N as needed. --Tack 2011/11/8 Hector Castro <hectcas...@gmail.com> > Hello, > > I'm currently in the process of evaluating solutions to index the contents > of ~1TB of SEC (Securities and Exchange Commission) documents.
