Adds optional query-planner and plan-adapter hooks to QuerySessionBuilder and exports the codec-1 decoder, raw projection batches and loss-reason decoder so an external data plane can plan over BAML profiles without copying these crates. Co-Authored-By: Claude Fable 5.1 <[email protected]>
Waits up to BAML_PROFILE_FLUSH_TIMEOUT_MS (default 60 s) for the profiler to persist and exits unsuccessfully if it cannot. Co-Authored-By: Claude Fable 5.1 <[email protected]>

DataFusion 54.1.0 SessionContext execute_logical_plan source validation authorization
💡 Result:
<search_synthesis>
In Apache DataFusion 54.1.0, the SessionContext::execute_logical_plan method is a low-level, feature-unlimited API [1][2]. It is designed to execute a LogicalPlan directly, meaning it does not impose built-in restrictions on the types of operations it performs, including DDL (e.g., CREATE TABLE) or DML statements [1][3]. It does not natively provide a mechanism for authorization or source validation [1]. If you require control over the types of operations allowed (e.g., to implement authorization or restrict certain statements), the recommended approach is: 1. Use SQLOptions: When executing SQL, use SessionContext::sql_with_options. This allows you to leverage SQLOptions::verify_plan to restrict the types of plans that can be executed [1][2]. 2. Manual Plan Inspection: If you are working directly with logical plans, you can implement a custom validation pass before calling execute_logical_plan. By inspecting the LogicalPlan enum, you can verify the statement type and ensure it complies with your security or validation requirements before execution. 3. Granular Execution Control: For finer-grained control over query execution and to avoid certain side effects, you can use SessionState::create_physical_plan after obtaining a plan, rather than calling execute_logical_plan directly, which is more appropriate for controlled, read-only, or strictly validated execution environments [1][4]. Because execute_logical_plan is a direct execution path, all responsibility for validating the source, checking authorizations, and enforcing security policies must be handled in your application layer before passing the plan to this method [1].

Revalidate the adapted plan before execution. baml_query::session::PlanAdapter is a public, unrestricted trait, and QuerySessionBuilder::with_plan_adapter is public. plan_and_run checks only the original plan before PlanAdapter::adapt; it then passes the adapter's replacement directly to SessionContext::execute_logical_plan. DataFusion 54.1.0 does not perform authorization or source validation for this API. An adapter can therefore add relations or scalar value functions that were not authorized. Run the complete authorization and relation validation on the adapted plan, or make the adapter a private trusted hook.

…plans A plan adapter may rewrite the logical plan. The gates now run on the plan that executes as well as on the plan the user wrote, so an adapter cannot introduce a backend-gated or value-reading function the scope may not use. No change when no adapter is installed. Verified with cargo fmt, cargo clippy -p baml_query --all-targets -D warnings, and cargo test -p baml_query (25 passed). The workspace-wide pre-commit clippy could not run on this machine: the linker rejects the macOS SDK stubs while building pyo3 build scripts, unrelated to this crate.

Closing: BAML Cloud will pin canary plus a small branch carrying only the planner hooks it still needs after the profiler port. The decoder exports for the old profile format are no longer needed. |

Issue Reference
No linked issue. Motivated by the BAML Cloud data plane (private repository), which today carries patched copies of
baml_queryandbaml_query_profilesbecause these extension points are private.Changes
Two independent commits; happy to split them if preferred.
1.
baml_query: session planner hooks and decoder exports (81 lines, no behavior change)Makes the query engine usable by an external planner without copying the crates:
QuerySessionBuilder::with_query_planner(...)andwith_plan_adapter(...), plus thePlanAdaptertrait. Both are optional; when unset the session behaves exactly as today. This is the same shape DataFusion exposes with itsQueryPlannertrait.decode_codec1(a captured value body),projection_batches(a profile into relation batches), andloss_unavailabilityplus theProfilesResolverre-export (why a value is unavailable).Nothing about any hosted system is in this commit; the planner that uses the hooks lives downstream.
2.
baml_cli: make the profiler flush part of a successful run (35 lines)On exit the CLI waited five seconds for the profiler to flush pending segments and ignored the outcome, so a large run could exit successfully with unpublished profile data. The CLI now waits for the flush to finish, up to
BAML_PROFILE_FLUSH_TIMEOUT_MS(default 60000, max 900000), and exits unsuccessfully if it cannot. Runs that already flushed within five seconds are unaffected.Testing
cargo fmt,clippypedantic with-D warnings).Screenshots
Not applicable.
