Module: PartitionGardener::Layout::ThreeArea

Defined in:
lib/partition_gardener/layout/three_area.rb

Overview

Every partitioning strategy targets the same three zones on the key axis:

archive  — coldest data; fine-grained children, retention-friendly, rarely written
current  — hot active span; most reads/writes; may contain heat splits inside the zone
future   — beyond the active window; sparse, less hot than current, not yet archived

Strategy plugins (date range, integer range, hash) only define how keys map to bounds. Heatmap collection and hot-bucket policy live on each strategy plugin. Executor cursor moves are identical: ORDER BY partition_key, conflict_key — strategy-agnostic.
