For what you want you need a disk server/linux cluster box of some kind, maybe with high availability raid.

Then, allow both servers to process read & write. When one fails the other is there by default. The disks are already there, mounted, served out by another box, so they do not have a failover problem.

This also solves the 'out of sync' problem.

This is almost exactly what everybody with a SAN is doing right now. Except for orders of magnitude lower cost. Our SAN costs us $US40 per MB; a PC with SATA can have a MB of raid for 2 orders of magnitude less. Circa $US1.00 - $US2.00 per MB.

mysqlnd_ms_match_wild - Finds whether a table name matches a wildcard pattern or not

SYNOPSIS
bool mysqlnd_ms_match_wild (string $table_name, string $wildcard) DESCRIPTION
Finds whether a table name matches a wildcard pattern or not. This function is not of much practical relevance with PECL mysqlnd_ms 1.1.0 because the plugin does not support MySQL replication table filtering yet. PARAMETERS
o $table_name - The table name to check if it is matched by the wildcard. o $wildcard - The wildcard pattern to check against the table name. The wildcard pattern supports the same placeholders as MySQL replication filters do. MySQL replication filters can be configured by using the MySQL Server configuration options --replicate-wild-do-table and --replicate-wild-do-db. Please, consult the MySQL Reference Manual to learn more about this MySQL Server feature. The sup- ported placeholders are: o % - zero or more literals o _ - one literal Placeholders can be escaped using . RETURN VALUES
Returns TRUE table_name is matched by wildcard. Otherwise, returns FALSE EXAMPLES
Example #1 mysqlnd_ms_match_wild(3) example <?php var_dump(mysqlnd_ms_match_wild("schema_name.table_name", "schema%")); var_dump(mysqlnd_ms_match_wild("abc", "_")); var_dump(mysqlnd_ms_match_wild("table1", "table_")); var_dump(mysqlnd_ms_match_wild("asia_customers", "%customers")); var_dump(mysqlnd_ms_match_wild("funny%table","funny\%table")); var_dump(mysqlnd_ms_match_wild("funnytable", "funny%table")); ?> The above example will output: bool(true) bool(false) bool(true) bool(true) bool(true) bool(true) PHP Documentation Group MYSQLND_MS_MATCH_WILD(3)
