Handling of large Codelists (ItemSchemes in general?) - Pagination?

[sosna]

(Was initially posted by @buhaiovos in the Issues list)

Hello!

Preemptively sorry in case this is a wrong communication channel. Are there any plans or maybe some approaches that already exist to handle queries for large codelists? Let's say we have a client-app that due to some limitations has issues dealing with a codelist that has a couple of millions of codes. Are there any "right" ways to implement partial request for a portion of a codelist to do some kind of pagination/lazy load of the codelist's contents?

Thanks!

This is not supported at the moment.

However, one of the open issues is related to pagination (cf. issue #50). While this was initially about data queries, we will consider your use case within this context too.

Out of curiosity, how large (i.e. how many items) are your codelists?

Sorry for a late reply. Thanks for the link!
So, currently we know for sure that we would have to deal with codelists which have ~300k codes. But in theory, we would need to support 1M case as well.

Perfect, thanks! I'll add this info to the respective issue.
