Avoid repeatedly retrieving the same objecttype when creating many new objects

Objecten API

Omschrijving / Description

Taiga Utrecht 333

When creating many objects, each POST leads to a GET on the objecttypes API.

"De error is afkomstig uit de controle of het objecttype/versie van het object bestaat, bij ieder nieuw (of update van bestaand) object zal de objecttype API worden aangeroepen."

"de situatie doet zich sporadisch voor, maar als het zich voordoet dan krijgen we zeer veel van dit soort foutmeldingen"

Caching for a short term of the objecttype would seem logical to me, but to be refined

Could one not use the notifications-api for this? You could theoretically cache the object-type until a notification about a new objecttype-version is published?

Even better would potentially be to merge the object-types and objects service into one physical service with a single database. Is there a reason why they're separated at the moment?

I've suggested a combined OpenObjecten a number of times, however this requires a more significant amount of development time. We can estimate both with Team Bron next week.

ObjectTypes don't send notifications upon changes, so your suggestion is interesting but currently won't work

Estimations:

• For adding ObjectType-caching to the Objects API: 2-3 days
• For OpenObjecten: the migration path from Objects API+ObjectTypes API will be quite complicated, as we don't see a workable path to convert the Objects API to OpenObjecten (this would require calling the OT API during datamigrations which feels hacky). So the best alternative would be to create a new OpenObjecten component and add a management command to migrate the data from an existing ObjectsAPI+ObjectTypes API to the new OpenObjecten component: 2-3 months of work. DH mentions that it would be workable if the API paths remain intact

@sdegroot graag je keuze en goedkeuring. Indien de tweede niet wordt gekozen dan splitsen we dit af in een aparte issue om breder op te pakken dan alleen met Utrecht

Vanuit Utrecht goedkeuring op de 2-3 dagen werk voor object-type caching. Het samenvoegen vereist nader onderzoek en betreft ook veel meer werk.

In principe zijn object type versies trouwens immutable. Enige uitzondering: de laatste versie zolang deze niet is gepubliceerd? Wellicht handig om configurable te maken.

Caching: to be limited to a short duration (1-5 minutes), should be configurable via an environment variable

OpenObjecten: split off into #564
