Optional Memcached local cache #3

Closed msh100 closed 7 years ago

msh100 commented 8 years ago

I am looking for a session handler for Datastore however in this I see there's also memcached.

Is there any reason against storing all session data within datastore (excluding cost)?

The reason I ask is because I do not intend to run this on AppEngine (GCP compute instances instead). I suspect this also means that I'd need to authenticate with a service account.

So this specific session handler has been written

  1. For AppEngine
  2. To be as fast as possible whilst still providing fully persisted session data

So it won't really work for you "as is".

The down side of what you are proposing is probably performance. The round-trip time would be higher than ideal from GCP without some sort of faster, local-ish cache (like Memcache/Redis).

Thanks for the reply. Performance was a concern, do you have any benchmarks for reading/writing to datastore? It seemed like a nice scaleable approach to session handling.

I got the impression the was indeed for AppEngine and not having to manage a KV store seems like a bonus :smile:

No figures.

Bear in mind when on Compute Engine you will have to use the REST API for Datastore. So each read or write will be an HTTP round trip.

I understand that, however I feel like these figures are still going to be very low and am tempted to dig into it a bit more. I will have a play around later to see what overhead there is from the REST API but I think it will still be pretty reasonable for production use.

If I get a chance to measure it I will update this issue with timings
