There is an issue that confuse me a bit, altough it is not important
for an operational point of view:
From the manual:
"The master server keeps a binary log of updates and an index file to
binary logs to keep track of log rotation. The slave, upon connecting,
informs the master where it left off since the last successfully propagated
update, catches up on the updates, and then blocks and waits for the master
to notify it of the new updates."
So, it seems that is the master that "pushes" information to the slave(s)
But I can also read:
"MySQL replication is based on the server keeping track of all changes
to your database (updates, deletes, etc) in the binary log
and the slave server(s) reading the saved queries from the master
server's binary log so that the slave can execute the same queries
on its copy of the data."
Here, seems that are the slaves that pop data from master.
So where is the truth ? Is the master that pushes or the slaves the pops ?
Or it is a combination of the two ?
Thanks.
