You have different ways to "synchronize/replicate" data from MySQL to Couchbase (or in the opposite direction).
- if you can afford to do that in a "batch" mode you can use ETL tools (Extract Transform and Load), such as Talend. Talend and Couchbase are now integrated : http://www.couchbase.com/press-releases/talend-and-couchbase-announce-pa... - We are working on a tutorial that shows how to do MySQL->Couchbase
- you can also in your application, code some logic to copy some information from MySQL to Couchbase, ad you can do that at different level/layer:
- directly in your application code (you connect to the 2 databases and push to both)
- in a messaging layer, for example you use a RabbitMQ server to save into MySQL and Couchbase
You really have different options, they are not complex, the important part is really "what/when do you need to copy the data?" and "what is the life cycle of this data?", ....
Also, I am not an XMPP expert, (neither MySQL), but I doubt that MySQL "supports" XMPP, it is more that some XMPP server have been implemented to store the messages and other informations into a MySQL (and other RDBMS). Since most of the XMPP server are open source, it is possible, if you have the time to do the same : create a storage provider for Couchbase.
