[infinispan-issues] [JBoss JIRA] (ISPN-11424) Deprecate StorageType Configuration in favour of MediaType

Deprecate StorageType Configuration in favour of MediaType ---------------------------------------------------------- Key: ISPN-11424 URL: https://issues.redhat.com/browse/ISPN-11424 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 11.0.0.Alpha2 Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes Priority: Major Fix For: 11.0.0.CR1 Currently caches have configuration to specify memory storing aspects that affects eviction, e.g. {code:xml} <memory> <object size="20000"/> </memory> {code} {code:xml} <memory> <off-heap size="10000000" eviction="MEMORY"/> </memory> {code} {code:xml} <memory> <binary strategy="EXCEPTION" eviction="MEMORY" size="5000"/> </memory> {code} Each of those configurations affect the format that the data will be stored, being {{object}} the default on-heap storage, {{off-heap}} the {{byte[]}} out of heap storage and {{binary}} an on-heap format that mix {{byte[]}}, {{String}} and primitives. This ticket proposes to have the {{MediaType}} of the keys and values to dictate the storage format, and let the {{<memory>}} element to be responsible to choose between on-heap and off-heap storage, eliminating the {{Binary}} option altogether. The configuration would be something like: {code:xml} <!-- Default configuration, heap storage with POJOs --> <memory storage="heap"> <eviction size="20000"/> </memory> {code} {code:xml} <!-- Storing java serialized objects, on-heap --> <encoding> <key media-type="application/x-java-serialized-object"/> <value media-type="application/x-java-serialized-object"/> </encoding> <memory storage="heap"> <eviction size="20000"/> </memory> {code} {code:xml} <!-- Off-heap configuration, in protobuf format --> <encoding> <key media-type="application/x-protostream"/> <value media-type="application/x-protostream"/> </encoding> <memory storage="off-heap"> <eviction size="10000000" eviction="MEMORY"/> </memory> {code}
