Hi
I am used to using Oracle (15 years) and MySQL(5 years), but I am planning to move an existing application from MySQL to Postgres. The reasons are very simple,
• New requirements means we need views, or a significant re-write
• Better query/index performance essential.
• Postgres and MySQL share a very common implementation of SQL-92, and what is missing can easily be implanted in functions
The only negative issue is replication. I have checked several Postgres Replication options and unsure which way to go. Can anyone recommend a replication option that meets the following:
• Does not use triggers. Usually slow, and one action that modifies several records, can trigger many actions on slaves/peers.
• Does use WAL, or other log, so that SQL DDL/DML is copied to slave/peer, rather than the result of the DDL/DML.
I think only Mammoth's ships WAL logs. Josh?
• Must provide master-master and master-slave replication
I don't think any of the solutions will do master-master.
• Simple to configure and maintain--------------------
Many Thanx
