org.apache.ignite.internal.portable.PortableSchemaRegistry

extends Object

Portable schema registry. Contains all well-known object schemas.

We rely on the fact that usually object has only few different schemas. For this reason we inline several of them with optional fallback to normal hash map lookup.
