📝 WalkthroughWalkthroughThe change adds idle-aware message consumption and wakeups, batched Kafka and NATS processing, reusable SQLx commit batches, and an opt-in distributed load-testing harness. ChangesIdle-aware bus runtime
Distributed load-testing harness
Reusable SQLx commit batches
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to Missing Kafka topics can be created without expected parallelism or redundancy, and persistent consumer failures may remain silent. The load harness also has smaller failure-path defects, so these issues should be addressed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@Makefile`:
- Around line 65-69: Update the load-host recipe and the corresponding
load-client target to include --database-url only when LOAD_DATABASE_URL is
non-empty, matching the existing load-run guard; preserve the separate
--sqlite-path argument and all other options.
- Around line 122-125: Update the broker environment-variable checks in the load
test suite’s start_bus path to treat both missing variables and empty values as
unset, so empty exports from the Makefile do not trigger external connections.
Preserve the existing behavior for non-empty broker URLs.
In `@src/bus/in_memory_bus.rs`:
- Around line 197-200: Update wait handling in both QueueSource and TopicSource
to create the wake Notified future before checking availability, recheck the
queue or topic after creating it, and await only when no work is present.
Preserve the existing immediate-ready behavior when work is available,
preventing notify_waiters() events from being lost between recv() and wait().
In `@src/bus/kafka_bus.rs`:
- Around line 187-198: Update the consumer cache used by the listener setup
around KafkaSource::connect so entries are keyed by group_id plus a
canonicalized topic set, ensuring different subscriptions create correctly
subscribed consumers; alternatively, synchronize a safe subscription-union
update before reusing an existing consumer. Add a regression test covering two
same-group listeners with different topic sets and verifying both receive their
requested messages.
In `@src/bus/postgres_bus.rs`:
- Around line 614-637: Update listen_wakeup and the insert_log notification flow
so log appends signal the distributed_bus_queue channel, including remote
inserts. After subscribing, make SqlLogSource::wait recheck the durable log
predicate before blocking so notifications racing with LISTEN cannot be missed;
preserve the existing wait behavior when no log is available.
- Around line 393-398: Update insert_queue so the bus_queue insertion and
pg_notify wakeup execute within the same database transaction, committing only
after both succeed and rolling back on failure. Preserve the existing
db_err("notify queue", err) mapping and send_message behavior while using the
transaction consistently for both statements.
In `@src/sqlx_repo/repo/commit.rs`:
- Around line 214-237: Update the retry handling in the ordinary commit function
around commit_sqlx_batch so the eighth retryable storage failure explicitly
returns the intended exhaustion error, rather than falling through to the
generic storage-error arm. Remove the now-unreachable trailing exhaustion return
and preserve retries and backoff for attempts before the eighth.
- Around line 219-227: Update the retry handling around commit_sqlx_batch so
ambiguous post-commit connection or timeout failures are not retried; only retry
errors proven to indicate rollback, or reconcile a stable batch identifier
before retrying. Preserve direct propagation for ambiguous storage errors, and
add a test covering a post-commit failure, including batches without streams and
protection against overwriting a newer snapshot.
In `@tests/load/src/bin/load-client.rs`:
- Around line 57-60: Update parse_usize to reject parsed values of zero and
return the existing validation error, while continuing to accept positive usize
values.
In `@tests/load/src/bin/load-suite.rs`:
- Around line 55-58: Update the --locks-only handling in the load-suite argument
parsing to set a dedicated locks_only flag, document it in print_help, and apply
a corresponding retain/filter in main so only lock cases remain; preserve the
existing --snapshots-only pattern and --no-locks behavior.
In `@tests/load/src/client.rs`:
- Around line 137-149: Call drain_pipeline before capturing pipelined_baseline,
after warmup and before measuring.store is set, so all warmup-enqueued messages
are applied before reading applied_ok and applied_err.
In `@tests/load/src/host.rs`:
- Around line 191-199: Update the sidecar cleanup in the path-handling code to
append “-wal” and “-shm” to the complete SQLite file path rather than using
Path::with_extension, so custom extensions such as “.db” resolve to the actual
sidecar files. Preserve the existing main-file removal and ignored cleanup
errors.
- Around line 341-347: Update wait_for_health so each request applies the
remaining duration until deadline as its timeout before send().await, ensuring
requests cannot outlive the overall timeout; derive this duration per loop
iteration rather than using a fixed timeout, and preserve the existing
health-check success behavior.
In `@tests/load/src/invoke.rs`:
- Around line 100-125: Update the completion handling in the non-pipelined
invoke flow to remove the corresponding id from pending on every non-success
outcome, including timeout, dropped receiver, and send failure, while preserving
successful result delivery.

both load-suite and load-client. Replace the local parser implementations with
calls to the shared parser, preserving existing suffix handling and error
behavior.
In `@tests/load/src/client.rs`:
- Around line 114-134: Update the worker loop around tokio::spawn to accumulate
successful elapsed_ms values in a worker-local Vec<f64> instead of locking
shared samples. Return each worker’s vector from the spawned task, then after
joining workers, extend the shared samples collection with each returned vector
while preserving the existing success and error counters.

Idle wait vs drain is an explicit RunOptions policy so listen() no longer treats an empty recv as EOF. SQL claim peeks before UPDATE; Postgres LISTEN/NOTIFY wakes waiters. Kafka creates subscribed topics before consume, reuses the consumer, and commits one high-water offset per fetched batch. NATS/Kafka expose batch fetch/produce. SQLite/Postgres commits retry BUSY_SNAPSHOT. tests/load is a workspace-excluded suite with applied and pipelined bus cells across memory/sqlite/postgres × direct/http/grpc/bus (nats, kafka, rabbitmq) plus locks and snapshot frequencies. Implements [[tasks/load-test-bench-1]] [[tasks/load-test-bench-2]] [[tasks/load-test-bench-3]]
Default features do not enable tokio. MessageSource::wait now yields once when no runtime is linked, and InMemoryBus parks on a crate-local notify instead of tokio::sync::Notify. Implements [[tasks/load-test-bench-3]]
