tblEventAlert needs
INDEX(associateID, eventAlertDateTime)

tblLink needs
INDEX(compID, dateTimeStartJourney)

int(5) is not what you think -- the 5 says nothing. Perhaps you meant
SMALLINT UNSIGNED ?
INT takes 4 bytes, limited to +/- 2 billion
SMALLINT UNSIGNED is 2 bytes, 0..65535

Will you have more that 64K rows in tblLink? If not, PARTITIONing is of little use.

Will you be removing rows from tblGeoFence when you purge old data from tblLink?

Will tblEmailLog and other tables need purging?
