> Olingo 4.10 (via OLINGO-1167) introduced a performance regression. Commit [https://github.com/apache/olingo-odata4/commit/ce5028d24f220ad0f60b5ac023c10e7b88b7c806] now makes resolution of EdmPrimitiveTypeKind create and suppress an exception for any non primitive type.
> Construction in EdmTypeInfo in 4.10 and 5.0 is very expensive and causes severe performance degradation on large datasets. For the same dataset, ODataJsonSerializer.getEdmProperty() spends <200 ms in Olingo 4.9 and ~3000 ms in Olingo 5 (15x slower).
> This same issue was originally reported in in Olingo 4.2 and fixed in 4.7 (via OLINGO-1357 and [https://github.com/apache/olingo-odata4/pull/51/files|https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fapache%2Folingo-odata4%2Fpull%2F51%2Ffiles&data=05%7C02%7Cfalbert%40ptc.com%7Cd24ae4d9097c4fcf037c08dc80c242c1%7Cb9921086ff774d0d828acb3381f678e2%7C0%7C0%7C638526819046368587%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=Y5ae4MIeiqxXLXbwJICWVMy0vQgfOohocPVmDqo1vlo%3D&reserved=0]).
