Monitoring

Three SHOW COMPUTE statements report runtime state and configured settings. SHOW COMPUTE STATUS and SHOW COMPUTE CONFIG default to the current graph and accept ON GRAPH <name> to target another. SHOW COMPUTE GRAPHS is a global listing — no per-graph form.

SHOW COMPUTE STATUS

Reports the live runtime state of the computing engine.

GQL
-- Current graph, compact form
SHOW COMPUTE STATUS

-- Named graph
SHOW COMPUTE STATUS ON GRAPH social

-- Per-component memory breakdown + planner stats
SHOW COMPUTE STATUS ALL
SHOW COMPUTE STATUS ALL ON GRAPH social

The basic form returns a compact (property, value) row set. Append ALL to add a per-component memory breakdown and planner statistics — this is an O(N) pass intended for operator debugging, not routine polling.

Identity & live cache

Property	Type	Notes
`graph`	string	Graph name. Always present.
`enabled`	boolean	Whether compute is enabled. Always present.
`syncMode`	string	`SYNC` or `ASYNC`. Always present.
`autoLoad`	boolean	Whether this graph's topology auto-rebuilds at database open (set via `ALTER GRAPH ... SET COMPUTE AUTOLOAD ON/OFF`). Persisted per graph; the `GQLDB_COMPUTE_AUTOLOAD` environment variable force-overrides it globally. Always present.
`available`	boolean	`true` once the topology snapshot is ready for queries. Poll this to detect build completion. Always present.
`nodeCount`	integer	Nodes currently in the cache. During a build, falls back to the in-flight build's estimate when the snapshot is not yet published. Always present (`0` if neither is available).
`edgeCount`	integer	Edges currently in the cache. Same fallback rule as `nodeCount`.
`topologyMemory`	string	Formatted bytes used by the topology cache. Always present.
`propertyMemory`	string	Formatted bytes used by the property cache. Always present.
`propertyCacheResident`	integer	Number of nodes whose properties are resident in the compute property cache. Present only when the cache holds properties or is partial.
`propertyCacheComplete`	boolean	`false` when the property cache is PARTIAL, meaning fewer nodes are resident than the topology holds because some were budget-skipped at build time (`PROPERTY_LIMIT` exhausted). Filtered reads on the skipped nodes fall back to storage even though `buildState` is `READY`, which can silently return incomplete results. Alarm on `false`, then raise `PROPERTY_LIMIT` and rebuild. Present only when the cache holds properties or is partial.
`propertyEdgeEntries`	integer	Number of edges whose properties are resident in the compute property cache. Always present. `0` while an edge label is configured via `SET COMPUTE PROPERTY` means the edge cache is ready but empty; a large value accounts for the edge share of `propertyMemory`.
`totalMemory`	string	Sum of topology + property memory. Always present.
`topologyVersion`	integer	Snapshot version, incremented on every rebuild. Present after first build.
`lowMem`	boolean	Whether the low-memory (32-bit topology) preference is set for this graph.
`topologyArrayWidth`	integer	Adjacency-array bit width of the live snapshot, `32` or `64`. Present after first build. `lowMem=true` with `topologyArrayWidth=64` means the preference is set but not yet applied, run `SET COMPUTE REBUILD`.

Sync / delta diagnostics (ASYNC mode signals; surfaced for wedge debugging)

Property	Type	Notes
`syncQueueDepth`	integer	Current pending writes in the sync queue. Always present (`0` is meaningful as a baseline).
`syncQueueCapacity`	integer	Configured queue capacity. Present only when configured.
`syncFallbacks`	integer	Times the engine fell back to a slow path because the queue was saturated. Present only when `> 0`.
`syncErrors`	integer	Apply errors counted since process start. Present only when `> 0`.
`lastApplyMs`	integer	Latency of the most recent delta apply, in ms. Present only when `> 0`.
`maxApplyMsLast1m`	integer	Maximum apply latency in the last minute, in ms. Present only when `> 0`.
`deltaSize`	integer	Bytes of un-compacted delta. Always present.
`deltaPendingCompact`	boolean	`true` when a delta compaction is queued. Present only when `true`.
`lastBuildEndedAt`	integer	Unix timestamp of the last completed build. Present only when set.

Process-level memory

Property	Type	Notes
`nodeIdCacheMemory`	string	Always-resident `_id` → internal-id map. Counts against the heap but not against `topologyMemory` / `propertyMemory`. Present when `> 0`.
`vectorIndexMemory`	string	Total heap used by the current graph's vector (HNSW) indexes. Counts against the heap but not against `topologyMemory` / `propertyMemory`. Present when the graph has vector indexes.
`fulltextIndexMemory`	string	Total heap used by the current graph's full-text indexes' in-memory structures. Counts against the heap but not against `topologyMemory` / `propertyMemory`. Present when the graph has full-text indexes.
`goMemLimit`	string	Effective `GOMEMLIMIT` (`unlimited (GOMEMLIMIT not set)` when unset). The Go runtime's soft memory cap — the actual ceiling on a build, regardless of physical RAM. Always present.
`goMemInUse`	string	Bytes the Go runtime has mapped and not released. Tracks against `goMemLimit`. Always present.
`heapInUse`	string	`runtime.MemStats.HeapInuse` — the in-use heap. Always present.
`memLimitUsedPct`	float	`goMemInUse / goMemLimit * 100`. Present only when `goMemLimit` is finite and `> 0`. Watch for `> ~90` — the Go GC starts spending most of its time collecting beyond that.

Configured limits (mirrored from SHOW COMPUTE CONFIG)

Property	Type	Notes
`memoryLimit`	string	Configured total-memory cap. Present only when set.
`topologyLimit`	string	Configured topology cap. Present only when set.
`propertyLimit`	string	Configured property cap. Present only when set.

Build lifecycle

Property	Type	Notes
`buildState`	string	Current build lifecycle state (e.g. `NONE`, `BUILDING`, `READY`). Always present.
`computeHealth`	string	Health summary for an enabled compute graph. Reports `ok` when healthy, a `degraded` message when the build is `READY` but the property cache is PARTIAL (some nodes were budget-skipped and are read from storage), or an `enabled but topology not built` message when compute is on but no snapshot is built or building. Each degraded message includes the remedial action. Present only when compute is enabled.
`buildInProgress`	boolean	Present only when a build is running.
`buildProgress`	float	Present only when `buildInProgress=true`; range `0.0`–`1.0`.
`nodesLoaded`	integer	Nodes scanned so far in the in-flight build. Present only during build.
`edgesLoaded`	integer	Edges scanned so far in the in-flight build. Present only during build.
`secsSinceProgress`	integer	Seconds since the build last advanced. Present only during build, only when `>= 30`. A growing value flags a wedge as distinct from a slow build.
`buildDuration`	string	Wall-clock duration of the last build (e.g. `2.5s`). Present once a build has finished.
`buildError`	string	Error message of the last failed build. Present only when the last build failed.

NOTE

available=true while buildInProgress=true is normal: in concurrent mode the topology publishes for queries before the property cache finishes loading.

ALL: per-component breakdown

Adding ALL appends extra rows after the regular output:

Property	Type	Notes
`memoryBreakdown`	string	Header row: `per-component (topology rows sum to topologyMemory; property rows measured live)`. Present when any component reports memory.
`<topology component>`	string	One row per topology component, formatted bytes. Rows sum to `topologyMemory`.
`<property component>`	string	One row per property component, formatted bytes. Measured live from the cache structures, so the sum may differ slightly from `propertyMemory` — that difference is itself a signal.
`plannerStatsDegreeKeys`	integer	Number of degree-distribution keys held by the planner. Present only on engines that derive planner stats.
`plannerStatsDeriveMs`	integer	Wall-clock cost of the last planner-stats derivation, in ms. Same availability rule.
`plannerStatsTopologyVersion`	integer	Topology version the planner stats were derived against. Same availability rule.

If the compute manager is not available for the graph, the result is a three-row table — graph, enabled=false, and a status message — instead of the full output.

SHOW COMPUTE CONFIG

Reports the persisted configuration (not live state) of the current graph. Useful for verifying a setup before enabling, or after a restart.

GQL
SHOW COMPUTE CONFIG

Rows returned:

Property	Value	Notes
`graph`	Graph name.	Always present.
`enabled`	`true` / `false`.	Always present.
`syncMode`	`SYNC` or `ASYNC`.	Present once any `SET COMPUTE` statement has been issued for the graph.
`memoryLimit`	Formatted bytes, or `unlimited` when not set.	Same as above.
`topologyLimit`	Formatted bytes, or `unlimited` when not set.	Same as above.
`propertyLimit`	Formatted bytes, or `unlimited` when not set.	Same as above.
`configVersion`	Integer; bumped on every config change.	Same as above.
`nodePropertyCache`	Formatted spec string, e.g. `:Person(name, age), :Company(*)`, or `(none)` when nothing is cached.	Same as above.
`edgePropertyCache`	Same shape, for edge labels.	Same as above.

For a graph that has never been touched with any SET COMPUTE statement, only graph and enabled=false are returned — there is no compute config to report yet.

SHOW COMPUTE GRAPHS

Tabular listing of all graphs in the database with compute enabled. Disabled graphs are omitted.

GQL
SHOW COMPUTE GRAPHS

Column	Type	Meaning
`graph`	string	Graph name.
`enabled`	boolean	Always `true` (disabled graphs are filtered out).
`available`	boolean	`true` once the cache is ready.
`nodes`	integer	Nodes in the cache.
`edges`	integer	Edges in the cache.
`memory`	string	Formatted bytes (topology + property).

Use this to audit which graphs are paying memory cost for the cache, and to find candidates for ALTER GRAPH ... SET COMPUTE DISABLED if their workload no longer benefits.
