Thanks for checking this. Below is a minimal snippet to reproduce the
original issue.
Reproduction snippet (Spark SQL):
val df = spark.createDataFrame(Seq(
("2024-01-10", "2024-01-01"),
("2024-01-05", "2024-01-01")
)).toDF("end", "start")
.selectExpr(
"datediff(cast(end as timestamp), cast(start as timestamp)) as diff"
)
df.collect()
When the timestamp columns are dictionary-encoded (as in Parquet), this used
to trigger an array length mismatch inside the Comet native datediff
implementation, resulting in a CometNativeException.
