Line 293 asserts "cache.hit" not in spans[1]["data"] but spans[1] is a db.redis span (as confirmed by line 286), not the cache.put span. The assertion should check spans[2] to properly verify that cache.put operations don't have a cache.hit attribute. This bug makes the test less effective since it's not validating the intended behavior.

The commands list is built by iterating over commands_seq (up to _MAX_NUM_COMMANDS items) and calling get_command_args_fn and _get_safe_command on each. However, when span is a StreamedSpan, this list is never used since the span.set_data call is skipped. This causes unnecessary CPU cycles for every Redis pipeline execution in streaming mode.

The expected_first_ten parameter is only used in the non-streaming branch (lines 205-210), but the test is parameterized with @pytest.mark.parametrize("span_streaming", [True, False]) combined with the expected_first_ten parametrization. This creates 4 test cases when only 3 are meaningful (2 for static + 1 for streaming), resulting in redundant test execution for span_streaming=True.
