RGST or RNST

Hi Charles,

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?
Thanks

    This information was described to you earlier by Charlie. It is not stored at the client, it is distributed across the system as needed as Charlie described earlier.

    Hi Mark
    it is distributed across the system as needed
    What does that mean?
    When does the RNST or RGST table move from one node to another?
    I have already understood that replication node can send update on RNST table with request answer.
    Thanks.

    I have already understood that replication node can send update on RNST table with request answer.
    That is how the information is distributed.

    Why so curious? Are you implementing your own distributed system?

    Hi mark,

    I just want to understand well how the system works.

    Yes, but the answer goes only to the clients not to other nodes. Isn't it ?

    It goes to all nodes and clients.
