Well, the next step... Back to the traditional 1->N replication.
Performance on the slave can be poor because of being single-threaded.
With your multi-source code, one could extend things further to have
multiple binlogs coming out of the 1 master and being applied in
parallel on each slave. This would allow [given that you "know what you
are doing"] you to configure traditional replication to run faster on
slaves. :)
I have one system with 100 dbs. These dbs are virtually independent.
Sometimes a flood of data goes into one db, thereby impacting any
inserts into other dbs. With the above code, I could have multiple
threads running on the slaves and get some parallelism, and improve the
SLAs.
