Supported Datatypes

fs2-cassandra makes use of shapeless’s tags to define custom types. Find below the current supported types:

Base Types

Scala	Cassandra
Int	int
Long	bigint
String	varchar
String @@ Ascii	ascii
Float	float
Double	double
BigDecimal	decimal
BigInt	varint
Chunk[Byte]	blob
UUID	uuid
UUID @@ Type1	timeuuid
FiniteDuration	bigint
InetAddress	inet
Enumeration	varchar

Collections and others

Scala	Cassandra
List	list
Vector	list
Seq	list
Set	set
Map[K, V]	map<k, v>
Tuple2[A, B]	frozen<tuple<a, b»
Tuple3[A, B, C]	frozen<tuple<a, b, c»

Example

import java.net.InetAddress
import java.util.UUID

import fs2.Chunk
import shapeless.tag._
import spinoco.fs2.cassandra.CType.{Ascii, Type1}

import scala.concurrent.duration.FiniteDuration

object TestEnumeration extends Enumeration {
  val One, Two, Three = Value
}

case class SimpleTableRow(
  intColumn: Int
  , longColumn: Long
  , stringColumn: String
  , asciiColumn: String @@ Ascii
  , floatColumn: Float
  , doubleColumn: Double
  , bigDecimalColumn: BigDecimal
  , bigIntColumn: BigInt
  , blobColumn: Chunk[Byte]
  , uuidColumn: UUID
  , timeUuidColumn: UUID @@ Type1
  , durationColumn: FiniteDuration
  , inetAddressColumn: InetAddress
  , enumColumn: TestEnumeration.Value
)
