This will require having the fast/slow disks partitioned into seperate volumes, and will also require that the _majorCompact code be modified to use the volume chooser to determiner where to put new files, instead of relying on srv:dir. This choice will be made based on the tablet that is being compacted using a user defined strategy for how to decide which volume to use. Needed: 1. New TieredStorageVolumeChooser 2. New configuration options for the volume chooser 3. Updates to major compaction code that determines the output file location (Specifcally around line 1945 of Tablet.java) 4. A VolumeChooserStrategy that can be user defined to allow users to define how to pick the new volumes ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
