pg-streaming-schema

Schema for data models of features and labeled data

_{Please have a look at the parent README first.}

This project is a Java library and contains the Apache Avro schema files for all other stream apps as well as a helper method to get Serializers and Deserializers (Serde).

Java code is automatically generated into the build folder and declared as a source set so generated Java classes can be used by other projects implementing this project.

Build the library

Required technologies

We use Gradle to build the library.

Please make sure to have the following technologies installed:

• Java / JDK (e.g., AdoptOpenJDK)
• Gradle

Simply build the entire multi-project from the parent directory or just the library by running:

gradle build

Based on the Avro schema files in src/main/avro, Java sources are generated in build/generated-main-avro-java and automatically marked as source set.

This library is also built as part of the parent multi-project.

How to use the library

Please have a look at the sibling projects.

For instance, a Serde (serializer and deserializer) can be initialized as follows:

Serde<FeatureKey> featureKeySerde=
        PgStreamingSerde.getSpecificAvroSerde(schemaRegistryUrl);
