void MaintenancePrioritizerLogCleanup::prioritize ( std::vector< RangeData > &  range_data, MemoryState &  memory_state, int32_t  prioritize, String *  trace  )

virtual

Assign priority for ROOT range

Assign priority for METADATA ranges

Compute prune threshold based on load activity

Assign priority other SYSTEM ranges

Assign priority for USER ranges

If there is no update activity, or there is little update activity and scan activity, then increase the block cache size

Implements Hypertable::MaintenancePrioritizer.
