Review Comment:
I have a test suite configuration mostly for completeness:
```cpp
INSTANTIATE_TEST_SUITE_P(
FixedSizedTypes, TestCDCSingleRowGroup,
testing::Values(
// Boolean
CaseConfig{::arrow::boolean(), false},
// Numeric
CaseConfig{::arrow::uint8(), false}, CaseConfig{::arrow::uint16(),
false},
CaseConfig{::arrow::uint32(), false}, CaseConfig{::arrow::uint64(),
true},
CaseConfig{::arrow::int8(), false}, CaseConfig{::arrow::int16(),
false},
CaseConfig{::arrow::int32(), false}, CaseConfig{::arrow::int64(),
true},
CaseConfig{::arrow::float16(), false},
CaseConfig{::arrow::float32(), false},
CaseConfig{::arrow::float64(), true},
CaseConfig{::arrow::decimal128(18, 6), false},
CaseConfig{::arrow::decimal256(40, 6), false},
// Binary-like
CaseConfig{::arrow::utf8(), false}, CaseConfig{::arrow::binary(),
true},
CaseConfig{::arrow::fixed_size_binary(16), true},
// Temporal
CaseConfig{::arrow::date32(), false},
CaseConfig{::arrow::time32(::arrow::TimeUnit::MILLI), true},
CaseConfig{::arrow::time64(::arrow::TimeUnit::NANO), false},
CaseConfig{::arrow::timestamp(::arrow::TimeUnit::NANO), true},
CaseConfig{::arrow::duration(::arrow::TimeUnit::NANO), false},
// Nested types
CaseConfig{::arrow::list(::arrow::int32()), false},
CaseConfig{::arrow::list(::arrow::int32()), true},
CaseConfig{::arrow::list(::arrow::utf8()), true},
CaseConfig{::arrow::struct_({::arrow::field("f0",
::arrow::int32())}), false},
CaseConfig{::arrow::struct_({::arrow::field("f0",
::arrow::float64())}), true},
CaseConfig{
::arrow::list(::arrow::struct_({::arrow::field("f0",
::arrow::int32())})),
false},
// Extension type
CaseConfig{::arrow::extension::json(), true},
// Use ParquetDataPageVersion::V2
CaseConfig{::arrow::large_binary(), false,
ParquetDataPageVersion::V2},
CaseConfig{::arrow::list(::arrow::utf8()), true,
ParquetDataPageVersion::V2}));
```
I can split this into two sets of cases, by default a small set would be
exercised but could be explicitly enabled by a gtest flag. Opinions?
