Like Scanamo for interacting with DynamoDB and use Scrooge for working with Thrift? Then you'll love ScanamoScrooge!
ScanamoScrooge provides automatic derivation of DynamoFormat
type classes for Scrooge generated classes based on Thrift struct and enum types.
Add scanamo-scrooge as a dependency to your build.sbt:
libraryDependencies ++= Seq(
"com.gu" %% "scanamo-scrooge" % "0.1.3"
)To bring DynamoFormats for Scrooge generated classes into scope, simply
import com.gu.scanamo.scrooge.ScroogeDynamoFormat._While, there is normally no need to explicitly reference DynamoFormat, the following
is an example of how it serialises classes based on the ChangeRecord
thrift definition.
scala> import com.gu.scanamo._
scala> import com.gu.scanamo.scrooge.ScroogeDynamoFormat._
scala> import com.gu.contentatom.thrift._
scala> import cats.syntax.either._
scala> val changeRecord = ChangeRecord(1L, Some(User("email", Some("f"), None)))
scala> DynamoFormat[ChangeRecord].write(changeRecord)
res0: com.amazonaws.services.dynamodbv2.model.AttributeValue = {M: {date={N: 1,}, user={M: {email={S: email,}, firstName={S: f,}, lastName=null},}},}
scala> DynamoFormat[ChangeRecord].read(DynamoFormat[ChangeRecord].write(changeRecord))
res1: Either[error.DynamoReadError, ChangeRecord] = Right(ChangeRecord(1,Some(User(email,Some(f),None))))
