[infinispan-issues] [JBoss JIRA] (IPROTO-155) FileDescriptors use too much memory

FileDescriptors use too much memory ----------------------------------- Key: IPROTO-155 URL: https://issues.redhat.com/browse/IPROTO-155 Project: Infinispan ProtoStream Issue Type: Bug Affects Versions: 4.3.3.Final Reporter: Dan Berindei Assignee: Nistor Adrian Priority: Minor E.g. a single {{persistence.counters.proto}} {{FileDescriptor}} instance uses 967KB. I'm not sure if the field documentation is useful for anything after the annotations have been parsed, but it is kept in memory, and in a hotrod-client test each {{DefaultCacheManager}} instance seem to need 3 instances of the string {{There is no native byte type in protobuf so it is mapped to int32.}} from the {{WrappedMessage.wrappedByte}} documentation. Many lists are {{LinkedList}} instances, even though a {{LinkedList}} with 3 elements uses more memory than an {{ArrayList}} with 10 elements. Some lists are also wrapped in {{Collections$UnmodifiableRandomAccessList}} twice. {{FileDescriptor}} {{HashMap}} fields ({{extendDescriptors}}, {{dependants}}) are never queried by key.
