case class AvroDeserializerExpression(child: Expression, schemaAvroJson: String, darwinConfig: Option[Config], avoidReevaluation: Boolean = true, useSchemaManager: Boolean = false) extends UnaryExpression with ExpectsInputTypes with CompatibilityAvroDeserializerExpression with Product with Serializable

An Expression which deserializes a binary field encoded in Avro and returns the corresponding representation in Spark.

child

the Expression containing the binary Avro to be deserialized

schemaAvroJson

the JSON representation of the Avro schema

darwinConfig

the configuration for the AvroSchemaManager

avoidReevaluation

this filed forces the Expression to be non-deterministic. Setting this to true measn that this expression is executed only once even though the Optimizer creates several copies of it (eg. it happens usually with CollapseProject if the value returned by the expression is used several times, as with a selection of fields of the struct returned). If you set this flag to false, the expression may be evaluated once for each occurence of ti you see in the physical plan.
