I Can't Log In!
At MultiPlan, we utilize a centralized web service to handle authentication requests and these requests occur between all layers of our application. One morning a server that handled authentication requests was functional, but performing slowly. And as a result, all of our applications were experiencing slowness and users were reporting they couldn't log in.
The following graph shows the severe blip in the authentication service's response time:
Calls to functions are logged directly on the Binary Log. Therefore if you don't have all functions created on all your servers you will break your replication and the SQL process will stop with an error.

mysql> insert into t VALUES(this_year());

Binary Log Management
Coupled with the changes to replica binary logging we will be releasing several updates to our tool that manages binary logs. This tool will be receiving updates to enable it to purge binary logs on replica databases. Along with this change we will also be adding a bunch of other features:
Quicker Initial Purge: Initial log removal (when master-bin.000001 exists) will now happen at 50% disk usage by default instead of 90%. This will reduce concerns about disk space …

…virtual head of our log ( Log sequence Number), the last place the log was flushed to disk ( Log flushed up to), and our last Checkpoint. The LSN grows forever, while the actual locations inside the transaction logs are reused in a circular fashion. Based on these numbers, we can determine how many bytes back in the transaction log our oldest uncheckpointed transaction is by subtracting our ‘ Log sequence number' from the ‘Last checkpoint at' value. More on what a Checkpoint…
