Summary: Currently SST files that aren't applicable to last_level_temperature nor file_temperature_age_thresholds are written with temperature kUnknown, which is a little weird and doesn't support CF-based tiering. The default_temperature option only affects how kUnknown is interpreted for stats. This change adds a new per-CF option default_write_temperature that determines the temperature of new SST files when those other options do not apply. Also made a change to ignore last_level_temperature with FIFO compaction, because I found that could lead to an infinite loop in compaction. Needed follow-up: Fix temperature handling with external file ingestion Pull Request resolved: https://github.com/facebook/rocksdb/pull/12388 Test Plan: unit tests extended appropriately.
