It is stored as binary data of jsonb format.
It utilizes current binary value and vector implementation. ListType Used to represent the List datatype. NullType OrdPrimitive A new type for WrapperType , complement the Ord feature for it. StringType TimeMicrosecondType TimeMillisecondType TimeNanosecondType TimeSecondType TimestampMicrosecondType TimestampMillisecondType TimestampNanosecondType TimestampSecondType UInt8Type UInt16Type UInt32Type UInt64Type VectorType VectorType is a data type for vector data with a fixed dimension.
The type of items in the vector is float32.
It is stored as binary data that contains the concatenated float32 values.DurationType IntervalType The “calendar” interval is a type of time interval that does not
have a precise duration without taking into account a specific
base timestamp. TimeType TimestampType JSON_TYPE_NAME LogicalPrimitiveType Trait bridging the logical primitive type with [ArrowPrimitiveType]. WrapperType Represents the wrapper type that wraps a native type using the newtype pattern,
such as Date is a wrapper type for the underlying native
type i32. json_type_value_to_string Converts a json type value to string parse_string_to_json_type_value Parses a string to a json type value parse_string_to_vector_type_value Parses a string to a vector type value
Valid input format: “[1.0,2.0,3.0]”, “[1.0, 2.0, 3.0]” vector_type_value_to_string Converts a vector type value to string
for example: [1.0, 2.0, 3.0] -> “[1.0,2.0,3.0]”
