Enable external user/framework defined Externalizers

Details

    • Documentation (Ref Guide, User Guide, etc.)

    Description

      Create an internal magic number (i.e. -1 or 255) for user defined externalizers. This is done to avoid users using our number space.

      So, internally: <magic_number> <stream>
      Users: <magic_number><user defined magic number (int)> <stream>

      Mandate unsigned ints so that we can optimise by sending them as variable lenght
      Internal frameworks could use high enough numbers for example up to 2 bytes: 5000, 7000, 20000
      1 byte: 128
      2 bytes: 32767
      3 bytes: ...

      GlobalConfiguration.registerMarshallable(Class type, Externalizer ext, int id);

      Maybe CacheManager better?

      CacheManager.registerMarshallable(Class type, Externalizer ext, int id);

      Future improvement, maybe generate ids automatically for user defined classes?

          Task - Represents a small unit of work that is not end-user facing. ISPN-246 Create tree and server module lifecycles to pass Externalizers

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
          • Closed

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) ISPN-805 Use custom externalizers to improve performance of Lucene Directory

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
