Can you tell us what is a typical installation of Oracle NoSQL Database ?
I mean what Oracle recommends in terms of:
- Number of data center
- Replication factor
- Number of replication groups
- Distribution of nodes across data center
- Consistency parameter
- Sync policy
- Rep Ack policy
Replication Factor: 3 is generally the most appropriate, but more is fine if you want to add read scalability.
Replication Groups: there is a chapter in the admin guide on sizing. Using this in conjunction with the spreadsheet in the distribution you can size the number of rep groups.
Consistency Parameter: whichever of the four options is appropriate for your application
Sync/RepAck policy: no_sync,simple_majority,no_sync.
