Variants

Null

Represents Avro null type, maps to Arrow’s Null data type

Boolean

Represents Avro boolean type, maps to Arrow’s Boolean data type

Int32

Represents Avro int type, maps to Arrow’s Int32 data type

Int64

Represents Avro long type, maps to Arrow’s Int64 data type

Float32

Represents Avro float type, maps to Arrow’s Float32 data type

Float64

Represents Avro double type, maps to Arrow’s Float64 data type

Binary

Represents Avro bytes type, maps to Arrow’s Binary data type

Utf8

String data represented as UTF-8 encoded bytes, corresponding to Arrow’s StringArray

Date32

Represents Avro date logical type, maps to Arrow’s Date32 data type

TimeMillis

Represents Avro time-millis logical type, maps to Arrow’s Time32(TimeUnit::Millisecond) data type

TimeMicros

Represents Avro time-micros logical type, maps to Arrow’s Time64(TimeUnit::Microsecond) data type

TimestampMillis(bool)

Represents Avro timestamp-millis or local-timestamp-millis logical type

Maps to Arrow’s Timestamp(TimeUnit::Millisecond) data type The boolean parameter indicates whether the timestamp has a UTC timezone (true) or is local time (false)

TimestampMicros(bool)

Represents Avro timestamp-micros or local-timestamp-micros logical type

Maps to Arrow’s Timestamp(TimeUnit::Microsecond) data type The boolean parameter indicates whether the timestamp has a UTC timezone (true) or is local time (false)

Fixed(i32)

Represents Avro fixed type, maps to Arrow’s FixedSizeBinary data type The i32 parameter indicates the fixed binary size

List(Arc<AvroDataType>)

Represents Avro array type, maps to Arrow’s List data type

Struct(Arc<[AvroField]>)

Represents Avro record type, maps to Arrow’s Struct data type

Interval

Represents Avro duration logical type, maps to Arrow’s Interval(IntervalUnit::MonthDayNano) data type
