fix(tests): skip regression tests on Ray runner, fix unused pytest import The interleaved-iteration tests call .to_arrow() on MicroPartition objects, which is NativeRunner-specific — on Ray runner iter_partitions() returns ray.ObjectRef and to_arrow_iter() would need ray.get(). The bug itself only exists in NativeRunner's plan cache, so skip both tests on Ray. Also fixes the F401 ruff error (pytest was imported but unused before the skipif marks were added).

test: fix regression tests to use interleaved iteration (the actual trigger) Serial executions do not reproduce the bug — try_finish clears the plan from the cache when a generator is fully consumed. The collision only fires when two generators are alive at the same time: a ScanTasks generator (read_parquet) occupies cache slot 0, then a concurrent InMemory generator (from_pydict) calls next() before the first is exhausted and hits the stale InputSender. Both new tests are verified to panic on 0.7.14 and pass on 0.7.5.

perf(daft-core): enum-dispatch multi-column equality comparator Replace the per-column `Box<dyn Fn>` dispatch inside build_multi_array_is_equal_from_arrays with an enum-dispatched comparator. Float columns now hold zero-copy ScalarBuffer handles (an Arc clone of the backing buffer) instead of reading values back through `dyn Array`, and the per-row hot path matches on a small enum rather than dereferencing a vtable per column. Public functions are unchanged and NaN/null semantics are preserved exactly: the float path reuses cmp_float, so NaN equality still honours the per-column nan_equal flag, -0.0 == 0.0, and null/null equality honours nulls_equal. Adds unit tests covering these cases.

feat(session): attach python data sources to sessions Adds session-managed data sources following the existing attach/detach conventions: attach_data_source, detach_data_source, get_data_source, has_data_source, list_data_sources, and read_source. Attached sources are stored in the Rust SessionState (Bindings<DataSource>), and the alias defaults to the source instance's name property. https://claude.ai/code/session_01EpJgPeoZXf3WPksSuemC65
