[jboss-jira] [Red Hat JIRA] (WFLY-14356) Infinispan heap-memory caches transcoding key/values unnecessarily

Infinispan heap-memory caches transcoding key/values unnecessarily ------------------------------------------------------------------ Key: WFLY-14356 URL: https://issues.redhat.com/browse/WFLY-14356 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 21.0.2.Final, 22.0.0.Final Reporter: Ryan Emerson Assignee: Paul Ferraro Priority: Major Fix For: 23.0.0.Beta1, 22.0.1.Final For local "heap-memory" caches, each key/value stored are being converted to a byte[] unnecessarily. The reason that this conversion is taking place, is due to a combination of 1) the key/value encoding type of Wildfly's "heap-memory" caches not being explicitly configured. 2) Wildfly using Infinispan in server mode by configuring [1]. This causes Infinispan `StorageConfigurationManager`[2] to configure the storage media type as `application/unknown`, which results in the `application/x-java-object` key/values being converted to byte[] on every put operation. The simplest solution is to update the "heap-memory" caches to explicitly configure the encoding as `application/x-java-object`. This will be mandatory in future versions anyway, as the `application/unknown` type has been deprecated. [1] https://github.com/wildfly/wildfly/blob/2bed1cae0c56d697ee0fc80b7f3390...
