From 03ca4173e2aeb16549cc61c40886bb99f8a54c58 Mon Sep 17 00:00:00 2001 From: Jonah Date: Fri, 6 Feb 2026 13:56:32 -0500 Subject: [PATCH 01/11] feat(OMN-1932): Wire snapshot publisher into registration handlers (Phase 3) Wire SnapshotPublisherRegistration into the registration orchestrator pipeline so state transitions produce compacted Kafka snapshots for read optimization. P3.1: Add schema_version (semver string) to ModelRegistrationSnapshot, simplify Kafka key to entity_id UUID only. P3.2: Add ops docs for compacted topic configuration. P3.3: Wire SnapshotPublisherRegistration in kernel bootstrap with best-effort Kafka producer lifecycle. P3.4: Add 500ms trailing-edge debounce per entity_id with flush-on-stop and tombstone bypass. P3.5: Handlers publish snapshots on introspection/ack transitions and tombstones on LIVENESS_EXPIRED. P3.6: Integration test verifying state transitions produce snapshots end-to-end with mock Kafka producer. --- docs/ops/snapshot_topic_configuration.md | 312 ++++++++++++ .../projection/model_registration_snapshot.py | 54 ++- .../projection/model_snapshot_topic_config.py | 18 +- .../handlers/handler_node_introspected.py | 50 ++ .../handler_node_registration_acked.py | 31 +- .../handlers/handler_runtime_tick.py | 33 +- .../node_registration_orchestrator/wiring.py | 15 +- .../snapshot_publisher_registration.py | 191 +++++++- src/omnibase_infra/runtime/service_kernel.py | 75 +++ .../runtime/util_container_wiring.py | 8 + .../test_snapshot_state_transitions.py | 455 ++++++++++++++++++ tests/replay/test_snapshot_plus_tail.py | 5 +- .../test_model_snapshot_topic_config.py | 26 +- .../test_snapshot_cache_operations.py | 3 +- .../test_snapshot_publisher_registration.py | 250 ++++++++-- 15 files changed, 1442 insertions(+), 84 deletions(-) create mode 100644 docs/ops/snapshot_topic_configuration.md create mode 100644 tests/integration/projectors/test_snapshot_state_transitions.py diff --git a/docs/ops/snapshot_topic_configuration.md b/docs/ops/snapshot_topic_configuration.md new file mode 100644 index 0000000000..f553698c37 --- /dev/null +++ b/docs/ops/snapshot_topic_configuration.md @@ -0,0 +1,312 @@ +> **Navigation**: [Home](../index.md) > [Operations](../operations/README.md) > Snapshot Topic Configuration + +# Snapshot Topic Configuration + +Operational guide for creating and managing the Redpanda compacted topic used by the ONEX registration snapshot publisher. + +## Overview + +The snapshot publisher writes compacted snapshots of node registration state to a Kafka topic so that dashboards and orchestrators can perform fast O(1) reads without replaying the event log.
