Here is the scenario. 2 web servers in two separate locations having two mysql databases with identical tables. The data within the tables is also expected to be identical i
The only way to ensure your tables are synchronized is to setup a 2-ways replication between databases.
But, MySQL only permits one-way replication, so you can't simply resolve your problem in this configuration.
To be clear, you can "setup" a 2-ways replication but MySQL AB discourages this.
