Allow mutation queries to contain multiple sequential statements that
execute atomically within a single transactional run. This enables
patterns like inserting a node and its edges in one query:
query add_and_link($name: String, $age: I32, $friend: String) {
insert Person { name: $name, age: $age }
insert Knows { from: $name, to: $friend }
}
Changes span the full compiler-to-execution pipeline:
- Grammar: mutation_body = { mutation_stmt+ }
- AST: QueryDecl.mutations: Vec<Mutation>
- IR: MutationIR.ops: Vec<MutationOpIR>
- Execution: loop over ops, accumulate affected counts
Cross-statement visibility works because each statement's commit_updates
advances the manifest state, so subsequent statements see prior writes.
Atomicity comes from the existing run mechanism (begin_run/publish_run).
