Infinispan Protostream

[pruivo]

Description

Replace the current JBoss Marshalling with Infinispan Protostream

Note: this is a backwards incompatible change, i.e., Infinispan cannot transfer JBoss Marshalling bytes into Infinispan Protostream and vice-versa.cannot

Motivation

Infinispan Protostream is based on Protocol Buffer. Infinispan 15 added support for proto3 syntax format (see https://protobuf.dev/programming-guides/proto3/). The main advantage is that proto3 fields are all optional, meaning they can be added or removed from Java objects without breaking compatibility (assuming a set of rules are followed: https://protobuf.dev/programming-guides/dos-donts/)

For Keycloak, the advantages are

• Seamless updates for cached entities.
• Sligthy better performance marshalling data when compared with JBoss Marshalling.
• Auto Generates the marshalling code based on annotated fields.
• Smaller byte arrays, reduce network data.
• Possibility to see the data in Infinispan Server Web Console (multi-site deployment).
• Query and indexing in Infinispan server (External Infinispan Deployments #28745).
