Type Members

1. case class FlatSchema(elems: ListMap[String, Map[String, String]], required: Set[String] = Set.empty[String]) extends Product with Serializable

   

   Flat schema container.

   Flat schema container. Contains self-describing properties in self and all primitive types as ordered flatten map in elems

   elems

   The ordered map of every primitive type in schema and it's unordered map of properties

2. type IgluSchema = SelfDescribingSchema[JValue]

   

   Self-describing Schema container for JValue

3. case class Migration(vendor: String, name: String, from: Full, to: Full, diff: SchemaDiff) extends Product with Serializable

   

   Class representing common information about Schema change, without details about specific DDLs

   Class representing common information about Schema change, without details about specific DDLs

   vendor

   Schema vendor

   name

   Schema name

   from

   source Schema version

   to

   target Schema version

   diff

   ordered map of added Schema properties

4. type MigrationMap = Map[SchemaMap, List[Migration]]

   

   Map of Schemas to all its possible target schemas Examples: com.acme/event/1-0-0 -> [1-0-0/1-0-1, 1-0-0/1-0-2, 1-0-0/1-0-3] com.acme/event/1-0-1 -> [1-0-1/1-0-2, 1-0-1/1-0-3] com.acme/event/1-0-2 -> [1-0-2/1-0-3] com.acme/config/1-1-0 -> [1-1-0/1-0-1]

5. type ModelGroup = (String, String, Int)

   

   Schema criterion restricted to model: vendor/name/m-*-* Tuple using as root key to bunch of Schemas differing only by addition (vendor, name, model)

6. type PropertyList = ListMap[String, Map[String, String]]

   

   List of Schema properties First-level key is arbitrary property (like id, name etc) Second-level is map of JSON Schema properties (type, enum etc)

7. type RevisionGroup = (String, String, Int, Int)

   

   Schema criterion restricted to revision: vendor/name/m-r-* Tuple using as root key to bunch of Schemas differing only by addition (vendor, name, model, revision) Hypothetical "lower" AdditionGroup could contain only one Schema

8. type RevisionMigrationMap = Map[RevisionGroup, MigrationMap]

   

   Intermediate nested structure used to group schemas by revision Examples: com.acme/event/1-0-* -> MigrationMap com.acme/event/1-1-* -> MigrationMap com.acme/config/1-1-* -> MigrationMap com.google/schema/1-0-* -> MigrationMap

9. type ValidMigrationMap = Map[SchemaMap, Validated[String, List[Migration]]]

   

   Failure-aware version of MigrationMap
