- Spark 4.1 `TimeType` casts have no explicit `Unsupported` arm; they fall
back implicitly but do not appear in the auto-generated compatibility doc
([#4490](https://github.com/apache/datafusion-comet/issues/4490)).
- `CAST(<map> AS <map>)` runs natively via `cast_map_to_map`;
`CometCast.isSupported` recurses into the key and value casts, so the map arm
inherits whichever support level the inner casts report.
- `spark.sql.legacy.castComplexTypesToString.enabled=true` is `Unsupported`
for any array/map/struct-to-string cast, so those casts fall back to Spark
while the flag is on. Comet only implements the default (`{}`-wrapped,
NULL-rendering) formatting. The flag is internal from Spark 4.0 onward and
defaults to false.
- - `CAST(<float|double> AS DECIMAL)` rounding may differ from Spark
(`Incompatible`, gated by `spark.comet.expression.Cast.allowIncompatible`,
tracked at [#1371](https://github.com/apache/datafusion-comet/issues/1371)).
+ - `CAST(<float|double> AS DECIMAL)` is `Compatible`: it rounds the shortest
decimal string form of the value (matching Spark's `Double.toString` +
`BigDecimal.setScale(HALF_UP)` path) rather than the binary value, taking a
guarded binary fast path for values provably far from a rounding tie. NaN and
infinity are null even in ANSI mode, matching Spark, which swallows the
`NumberFormatException` from `Decimal(double)` before the ANSI overflow check.
The support level carries a note: `Dou [...]
- Spark registers the type-name conversion functions (`bigint`, `binary`,
`boolean`, `date`, `decimal`, `double`, `float`, `int`, `smallint`, `string`,
`timestamp`, `tinyint`) as cast aliases. Each lowers to the same `Cast` node,
so Comet handles it via the `cast` implementation with the same compatibility
profile.
- Performance (tuned 2026-07-14, PR
[#4920](https://github.com/apache/datafusion-comet/pull/4920)): narrowing
integer casts (`spark_cast_int_to_int`) map the values buffer in a single pass
with Arrow `unary`/`try_unary` and carry the null buffer over untouched,
replacing an element-by-element `Option`/`Result` iterator-collect. Up to 100x
faster on narrowing casts. Benchmark: `benches/cast_numeric.rs`.
- Performance (tuned 2026-07-15, PR
[#4940](https://github.com/apache/datafusion-comet/pull/4940)):
float/double-to-decimal casts (`cast_floating_point_to_decimal128`) now convert
in a single vectorized `unary_opt` pass that maps out-of-range values (NaN,
infinity, precision overflow) to null, replacing the per-element
`Decimal128Builder` loop. ANSI raises via an O(1) null-count check plus a rare
element-wise rescan. 15-36% faster with no regression on any shape. Benchmark:
`benches/cast [...]
