ESI Update cycles when extracting data from game

EVE Technology and Research Center Third Party Developers

Hi,

I’ve built a simple tool for my alliance mates to check which system should be farmed in order to raise the ADM indexes.

The request URL is this one according to EVE Swagger : “https://esi.evetech.net/latest/sovereignty/structures/?datasource=tranquility”.

I was wondering why the data I get, and even the data EVE Swagger gets, is not updated accourding to in-game data.

For instance, in-game, a system is >4.0 ADM index, but on my tool, it still is <4.0 ADM index.
On Dotlan as well.

Why is that ?
Is my request badly built ?
Or is that intended ?
For what reason ?

Why prices, for instance on market hubs are almost “live”, while they change every seconds, and thousands of changes / updates are made, and ADM, which are fewer than items / orders / order updates, are not ?

What is the actual “update cycle”, if there are any ?
Does it only update at DT ?
Is that the only type of data that is not “live” ?
How can you tell which data / request will be updated at a certain paste ? In response Headers ?

Yes, there’s a cache header Expires which tells you when the cache will be refreshed.

this one ?
Why is it that this time has passed, and data has not been updated according to in-game data then ?

That’s odd.

Yep, maybe there’s something i don’t well fully understand or know ?
Even in Dotlan, it’s not updated.

For anyone wondering about it as well, i got an answer :

The issue has been pointed out 1.5 years ago though…
So we won’t get a change tomorrow…
