Is there a way to get the exact datacenter the user hits?

Not just the region?

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 5:56 PM

I.e. I would like to create a KV key per datacenter

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 5:59 PM

So I'd have to do that on every worker request essentially? What kind of overhead would that put up?

Few milliseconds.

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:00 PM

Or would it not be much at all since it's served from within the datacenter

KDX_MW | Kaddex.xyz / Ecko.xyz

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:00 PM

Why would you want to do this though? There is no guarantee the user hits the same datacenter.

I am building a logging solution that will track API key and I just want to sum up all the API keys at the end of month to get usage.

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 6:00 PM

So I will put a key for each datacenter location then iterate through at end of month and sum up # of requests.

Haven't found an easy way to call it from workers to get a summary of # of API calls (i.e. to shut customer off)

Will try that out shortly thank you :). Will analytics be more cost effective than KV? And any slowness with it?

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:12 PM

I.e. if a worker uses an analytics engine does it have to go to another DC or centralized source?

KDX_MW | Kaddex.xyz / Ecko.xyz

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:13 PM

Oh wow looks like it’s got lots of features

KDX_MW | Kaddex.xyz / Ecko.xyz

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:13 PM

Will swap over to that…

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:14 PM

Does each DC have locally available analytics engine endpoints that are eventually replicated across?

Got it. Probably Kv better for now as I could be upwards of a million requests a second

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:16 PM

Which for Kv is $25 to write and $5 to read

just to be accurate, KV reads are $0.50/M, and writes/lists/deletes are $5/M

KDX_MW | Kaddex.xyz / Ecko.xyz

K

KDX_MW | Kaddex.xyz / Ecko.xyz•12/17/23, 7:18 PM

I.e. at same interval as the KV population?

So best bet is write to analytics engine, then have a worker run every 300 seconds or so and pull the data out to populate the KV pair with the latest total sum requests

cron for each customer doesn't work though, you still have the 1000 subrequest limit, so unless you call the worker with a service binding, I recommend looking at DO alarms

although not recommended for all workloads, you can put cache in front of KV, so you only even query KV if your cache (which is free) has expired or evicted
