From a096a7faa35b345c765102201a5a09cc03ef541a Mon Sep 17 00:00:00 2001 From: ToineSiebelink Date: Thu, 20 Oct 2022 18:34:29 +0100 Subject: Read Performance Improvement - Using Native Query - Native query for FragmentExtracts - Convert FragmentExtracts to tree of FragmentEntity - Native Query now used for all Gets with descendants (orignal hibernate option only used when descendanst ommited) - Added error handling for not-found on native query - Ommit descendants by default on many udpate use-cases (this might have a signifcant perf. improvemnt impact too) - Improved legacy tests for delete use-cases - Corrected performace test expectation - Fix TTL test realizing TTL resolution is whole seconds!
