Recover Disk Space: Easy THL Clean-Up In Tungsten v7
Transaction History Log (THL) files are the core of Tungsten Replication, containing the actual MySQL write events that are replicated to the replicas. These files can take up considerable amounts of disk space, making them of interest for housekeeping operations to limit the consumption and ultimately, the cost. This blog post will walk you through THL management, along with the new command `tpm purge-thl` which helps automate the process when THL needs to be removed prior to the automatic rotation window.
