Hi there,
we have a customer requirement that an application server will talk to an XML database. The production system (app server + db) will reside in a data center near the customer. However the customer requires having a fail-over installation in a different data center (in a different geographical location) in the case of disaster or whatever.
As far as I see BaseX does not support multi-master replication. What are the best approaches for dealing with a fail-over where the fail-over database should have a copy of the production database that is as recent as possible?
Andreas
Hi Andreas,
In some of our applications, we create regular backups of the databases (using the client/server architecture) and send them to the second server. In one application, we are exporting the databases as XML, and we push/pull data with git, as this way only the incremental changes will be updated.
Obviously, these approaches are not as low level as an integrated replication trigger would be. We've been experimenting with automatic replication for a while now, but our current solutions are not production-ready (mainly because our existing approaches meet the requirements of our own commercial use cases..).
Hope this helps, Christian
