Display all information after a specific sequence number
This may be used when you have had a Primary failover or would like to see everything that happened after a certain event. It will read the start position from the sequence number passed and allow you to see all events, even if they were not extracted by the replication service.
If you provide the --source option, the script will SSH to the host in question and read its THL information.
Display information between two sequence numbers
This will show the raw Primary data between the two sequence numbers. It is inclusive so the information for the --low option will be included. This will only work if the sourceId for both sequence numbers is the same.
tungsten_read_master_events --low=4582 --high=4725
The script only works with MySQL at this time.
