[GSS] (7.0.z) HHH-10563: Significant String use/duplication associated with subselect fetch

    Description

      The use of @Fetch(FetchMode.SUBSELECT) results in a significant level of string duplication for SQL and SQL fragments. When loading large datasets and/or higher numbers of associations with multiple associations using SUBSELECT the memory can accumulate significantly (e.g. on the order of multiple GB for string space associated with the duplicate SQL fragments alone).

          • 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.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
