As several different approaches to "replication" involve same requirements and/or touching the same places in code it seems a good idea to at least get some more or less formal descriptions from parties involved. Also, it seems that largely the same things are needed for other projects, like precomputed/materialized views and auditing or some other non-replication data moving methods. While each of the replication and non-replication projects does do its own thing, it may still be beneficial to try to provide some hooks in right places for them. Not all projects need to use all of them but having all projects patch the same places in core code will make it pretty much impossible to use more than one at a time. As an example, one may want to have both synchronous auditing data and async replication to be done on the same live database, both gathered at the point of data manipulation and both moved to different machines. -- ---------------- Hannu Krosing Database Architect Skype Technologies OÜ Akadeemia tee 21 F, Tallinn, 12618, Estonia Skype me: callto:hkrosing Get Skype for free: http://www.skype.com
