I'm running a single slave off a MySQL master. I'm using this version:
Ver 14.14 Distrib 5.7.13, for linux-glibc2.5 (x86_64) using EditLine wrapper
The problem I have is that the system will replicate quite happily for a day or so and then something hits it and the log files on the master grow hugely.
The data directory for the database is about 9.5GB in size.
When the replication problem happens, the log files can take up 175GB of disk space in a very short amount of time (filling the disk).
How do I debug what is happening? Can anyone suggest what to look for in the database operations that may cause this huge blow-out?
