* @file blr_cache.c - binlog router cache, manage the binlog cache
|
|
*
|
|
* The binlog router is designed to be used in replication environments to
|
|
* increase the replication fanout of a master server. It provides a transparant
|
|
* mechanism to read the binlog entries for multiple slaves while requiring
|
|
* only a single connection to the actual master to support the slaves.
|
|
*
|
|
* The current prototype implement is designed to support MySQL 5.6 and has
|
|
* a number of limitations. This prototype is merely a proof of concept and
|
|
* should not be considered production ready.
