Field Details

prevFlusher

protected transient UpdateCommitter<com.illumon.iris.db.v2.sources.ArraySourceHelper<Boolean,byte[]>> prevFlusher

The presence of a prevFlusher means that this ArraySource wants to track previous values. If prevFlusher is null, the ArraySource does not want (or does not yet want) to track previous values. Deserialized ArraySources never track previous values.
