This module produces Java class files for Feast's data type and gRPC service definitions, from Protobuf IDL. These are used across Feast components for wire interchange, contracts, etc.

End users of Feast will be best served by our Java SDK which adds higher-level conveniences, but the data types are published independently for custom needs, without any additional dependencies the SDK may add.

<dependency>
  <groupId>dev.feast</groupId>
  <artifactId>datatypes-java</artifactId>

</dependency>

The .proto definitions are packaged as resources within the Maven artifact, which may be useful to include them in dependent Protobuf definitions in a downstream project, or for other JVM languages to consume from their builds to generate more idiomatic bindings.

Google's Gradle plugin, for instance, can use protos in dependencies either for include or to compile with a different protoc plugin than Java.

sbt-protoc offers similar functionality for sbt/Scala.

TODO: this module should be published to Maven Central upon Feast releases—this needs to be set up in POM configuration and release automation.
