Structs

CompactionTransition 🔒

CompactionTransitions 🔒

Actor-level plans generated from the current graph for one compaction round.

IcebergV3FragmentPartition 🔒

Actor-independent fragment partitioning shared by every compaction round. Scaling may replace actors and placements, but does not change which fragments belong to each execution phase.

RenderedResolver 🔒

The resolver fragment is rendered and placed with the whole Iceberg graph, but remains disconnected until a compaction command activates it.

Functions

build_compaction_transitions 🔒

build_transition 🔒

contains_resolver 🔒

ensure_writer_relation 🔒

find_writer_node 🔒

partition_resolver 🔒

Split the dormant resolver from an Iceberg graph after actor placement and before edge construction. The complete relation map must be used during rendering so a no-shuffle resolver edge participates in actor alignment.
