ACE Commands

This section documents the ACE (Active Consistency Engine) CLI commands. Be sure you review and meet all of the ACE configuration requirements before using any ACE command:

Basic ACE diff and repair Commands

Command	Description
repset-diff	Runs table-diff on every table in a specified replication set and aggregates results.
schema-diff	Compares objects (and optionally data via per-table diffs) across nodes for an entire schema.
spock-diff	Compares Spock metadata/state across nodes to find configuration divergences.
table-diff	Compares a single table across cluster nodes and writes a diff report (JSON/HTML/CSV).
table-repair	Applies fixes from a diff file using a chosen source-of-truth node; supports dry-run, upsert/insert-only, and --fix-nulls for NULL-only drifts.
table-rerun	Re-runs a previous diff from a saved file to verify that inconsistencies were resolved.

Merkle Tree (mtree) Commands

Command	Description
mtree build	Builds Merkle trees for a specific table on all nodes (after mtree init).
mtree init	Creates required schema/objects and sets up CDC (publication/slot) for Merkle operations.
mtree listen	Long-running process that consumes CDC and continuously updates Merkle trees.
mtree table-diff	Compares Merkle trees across nodes to detect inconsistencies; can emit JSON/HTML reports.
mtree teardown	Removes all Merkle-related objects and CDC setup created by mtree init.
mtree teardown-table	Drops Merkle data/metadata for one table and removes it from CDC publication.
mtree update	Applies captured CDC changes to refresh Merkle trees; optional rebalance.
