Support for non-String keys in the rest server ---------------------------------------------- Key: ISPN-8427 URL: https://issues.jboss.org/browse/ISPN-8427 Project: Infinispan Issue Type: Enhancement Components: Server Affects Versions: 9.2.0.Alpha1 Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes The rest server assumes keys are always String, causing interoperability between remote endpoints limited. When a cache is written via Hot Rod, by default keys will be stored as marshalled {{java.lang.String}} via {{JBossMarshaller}} (the default marshaller), or via UTF-8 in case the {{UT8Marshaller}} is chosen. The Rest server should accept keys in different formats than String, using an encoding for byte[] values like Base64, and pass in an special header with the key media type so that the server can use it. With this capability, compat mode could be avoided when writing from Hot Rod and reading from Rest and vice versa
