Example programs

The repository includes complete GQL programs. Each program creates its own graph, so use a fresh in-memory invocation or a new database directory for each run.

cargo run -p graphfusion --locked -- run --file examples/social.gql
cargo run -p graphfusion --locked -- run --file examples/analytics.gql
cargo run -p graphfusion --locked -- run --file examples/paths.gql
cargo run -p graphfusion --locked -- run --file examples/path-patterns.gql
cargo run -p graphfusion --locked -- run --file examples/element-references.gql
cargo run -p graphfusion --locked -- run --file examples/transactions.gql

Program	What it demonstrates
social.gql	Create a graph, insert a chain, update Alice and find Cara
analytics.gql	OPTIONAL MATCH, aggregation, percentiles, UNION ALL
paths.gql	Tied shortest paths and quantified-edge lists
path-patterns.gql	Repeated groups and conditional paths
element-references.gql	Element aliases, property lookups and path elements
transactions.gql	Commit and rollback across statements

Add --explain to inspect the DataFusion plans. It executes the program, including writes; it is not a dry run.

Reference-page examples

Unless a page creates its own graph, graph examples use the Alice → Bob → Cara graph from the quickstart, with ages 30, 40 and 25 and the graph selected in the session. Run them after that setup in the same session, or prepend USE GRAPH social when reopening a durable database.

Rust examples are available with cargo run -p graphfusion --example scalar --locked and cargo run -p graphfusion --example social --locked.
