ToolUp.Graph.InMemory

The zero-dependency default IGraphStore — the GP-2 floor. A consumer with default ServerConfig composition gets a working graph store with no external dependency and no added NuGet package.

What it is

  • Per-scope adjacency lists held as immutable ScopeGraph snapshots, one per tenant scope, so scopes are partitioned by construction (GP 4).
  • A bounded openCypher subset interpreter — the documented portability floor. A query that runs here is guaranteed to run against every engine companion; the reverse is not promised.

What it is not

  • Not a full Cypher engine. Out-of-subset constructs throw CypherSubsetException naming the clause — never a silently-wrong result. Compose an engine companion (Kùzu / Neo4j / AGE) for full Cypher.
  • Not durable. No snapshot-to-disk. It is a development / test / small-single-instance default; durable storage is what the engine companions bring.

Supported openCypher subset

MATCH  (n[:Label] [{prop: <lit>, ...}])
     | (a[:L]) <rel> (b[:L])
[WHERE <var.prop <op> <lit>, combined with AND / OR / parentheses>]
RETURN <var | var.prop> [AS alias] (',' ...)*
[ORDER BY <var.prop> [ASC|DESC]]
[LIMIT <int>]
  • <rel> is -[:T]->, <-[:T]-, or -[:T]- (undirected); the type T is optional and [r:T] binds the relationship variable (single hop only).
  • Variable-length paths: -[:T*lo..hi]->. Traversal is cycle-safe — a visited-node set guarantees termination on cyclic graphs.
  • <lit> is 'str' / "str" / int / float / true / false / $param.
  • Comparison operators: =, <>, >, >=, <, <=.

Out of subset (throws CypherSubsetException): CREATE / MERGE / SET / DELETE / WITH / UNWIND / OPTIONAL / CALL / aggregation functions / RETURN * / SKIP / UNION / multi-hop patterns / multiple comma-separated patterns.

Concurrency

Reads take the current immutable snapshot with no lock; per-scope mutations serialise the read-modify-write behind a short monitor lock that wraps only synchronous pure transforms (never held across an await). A concurrent reader never observes a half-applied mutation.
