I can see RGST (Replication Group Sate Table) in http://www.oracle.com/technetwork/database/nosqldb/learnmore/nosql-database-498041.pdf page 10 (subsection "Client Driver" for example).
I can see RNST (Replication Node State Table) in http://hpts.ws/sessions/cwl-hpts-for-website.pdf page 18 (subsection "Locating Data: Rep Node State Table").
Are RGST and RNST the same thing?
If not what is the difference? Where is stored RNST? At the client?
