Backend: split signed URLs gen #367

Open Bartalog opened 6 years ago

Bartalog commented 6 years ago

Current behavior:

/new-gcs-urls generates PUT URL (~100ms), then GET URL(~100ms)

Desired behavior:

/new-gcs-urls generates PUT URL (~100ms)
then the GET URL(~100ms) is generated in the background, and saved to Memcache

Drawbacks:

the workflow becomes more complex
the gain (if any) is small
spawning a new background task with taskqueue.Add can be as expensive as the computation itself

Bartalog commented 6 years ago

The new runtime go1.11 may allow multi-core processing, which could speed up the concurrent generation of PUT URL and GET URL. To be tested!

The 2nd gen GAE runtimes with go111 are much faster at generating signed URLs. Not sure however that concurrent processing would reduce total latency, though.
