I have limited experience with MYSQL replication; which is why I am hoping others with more experience can answer a question or two. Let's say I have a MASTER MYSQL database. Let's say there are 50 - 60 other systems where I'd like to have MYSQL running on these "slave" systems. These slave systems need to be kept in synch with the Master, but it does NOT need to be anywhere near real time. The data in the slaves could lag as much a an hour or two. The amount of data in total in the MASTER is in the range of 100MB - 250MB The rate of changes to the data is in the range 2000 - 5000 DML per 24 hour day. We control the application so we can/will include date/time each record is created or modified. You can assume that no records ever get physically deleted; only INSERT & UPDATE (no DELETE).
What are some alternative ways to keep the slave systems "current"? TIA & HAND!
