+## approx_count_distinct

+- Spark 3.4.3 (2026-07-03): registered as
`expression[HyperLogLogPlusPlus]("approx_count_distinct")`, an
`ImperativeAggregate` that hashes each non-null input with `XxHash64` (seed 42,
floats normalized via `NormalizeNaNAndZero`) and keeps a HyperLogLog++ register
buffer of `numWords` `Long`s (10 six-bit registers per word). The cardinality
is estimated with linear counting for small inputs and bias-corrected HLL
otherwise. Comet ports `HyperLogLogPlusPlusHelper` exactly, including the b
[...]
+- Spark 3.5.8 (2026-07-03): algorithm and tables identical to 3.4.3.
+- Spark 4.0.1 (2026-07-03): `HyperLogLogPlusPlusHelper` moved to
`catalyst.util` and `XxHash64Function.hash` gained collation parameters, but
for the default `UTF8_BINARY` collation and non-string types the hash value is
unchanged, so results match 3.4.3.
+- Spark 4.1.1 (2026-07-03): identical to 4.0.1.
+
## any
- Spark 3.4.3 (audited 2026-05-26): registered as a SQL alias of `BoolOr`,
which extends `RuntimeReplaceableAggregate` with `replacement = Max(child)`.
Catalyst rewrites `any(x)` to `max(x)` before Comet sees the plan, so `any` is
served by `CometMax` on a `BooleanType` column.
