Enum CompactionStyle

Compaction style.

public enum CompactionStyle

Fields

Fifo = 2: First-in, first-out. Never really compacts; it deletes the oldest files once a size or age bound is passed. For time-series and cache data where losing the oldest entries is acceptable, and wrong for anything that must be kept.
Level = 0: Levelled compaction, the default. Keeps read amplification low and space overhead small, at the cost of writing data several times as it moves down the levels.
Universal = 1: Universal compaction. Writes each piece of data far fewer times, so write-heavy workloads go faster, but it can transiently need close to twice the database size in free space and reads touch more files.
