I used google to try and find some solutions / clues and all the

This was however recently done on the database to increase this to
4Gb already.

Thank you for the response...
My question now is, will I be able to set the innodb buffer pool size for
the slave server to be the same as the master server?
If so, can I only restart the slave server and keep the master server
running in order to cancel out the requirement for downtime?

In less technical terms, if the master goes faster than the slave, the slave
will puke.

MySQL doesn't support dynamic distribution of data among partitions. The usual
method is to create a partition for each fixed chunk of time, such as for each
month/week/hour/day or whatever time slice breaks your data up in the
manageable pieces. Note that a very large number of partitions (
