Async non-blocking call to datastore? [requires gRPC support]

[susanlinsfu]

Will there be any support for async non-blocking calls to the datastore?

[mziccard]

Hi @susanlinsfu thanks for your interest.
I think that support for async non-blocking calls will be added once we migrate to gRPC for the transport layer. But I don't have a date to tell you yet. Maybe @jgeewax and @aozarov have more information than I do.

[aozarov]

Yes, as @mziccard said, we do plan to provide async calls to the Datastore API but
that would be part of the transition to gRPC which will happen early next year (no exact date yet).

[susanlinsfu]

gRPC has now come to the datastore. Is there a date yet when async features will be released?

[aozarov]

It is in the roadmap but unfortunately no dates yet.

[susanlinsfu]

Thanks for the very quick response! If it means anything at all I am really pushing for this feature as spinning up threads for every request really is killing performance! :)

[aozarov]

Until then you should consider grouping operation when possible using batches.

Closing out this issue - even if we left it open, we might overlook updating it when we add gRPC support to datastore. It's not scheduled yet even now.

This is a very important request. Not sure how you want to track asks like this.

[garrettjonesgoogle]

I think I will re-open this one due to the attention on it.

Perhaps we can incorporate parts of Spotify's library.

This is blocked on support for gRPC in app engine.

We've made it work, I'm going to test again, but I can do gRPC in GAE Std 7.

GRPC functions on Java8 Standard can we please move forward with using GRPC as transport for Datastore? Thanks

[garrettjonesgoogle]

I have removed the blocking label since grpc can be used on GAE Java 8 standard.

This has been added to our feature backlog: https://github.com/GoogleCloudPlatform/google-cloud-java/wiki/Feature-backlog. This issue will be closed but is linked in the backlog and can continue to be used for comment and discussion.

Google Cloud Datastore API is much slower than Google AppEngine Datastore API. Nonblocking calls are one approach to a work around. Please implement them.

[chbatey]

Any update on when this will be implemented?

[iozozturk]

Hey team, any news?

[myashchenko]

hey, any plans to make async API for Datastore?

[ghost]

Any update here? Seems odd to not have gRPC for database calls, the performance difference between HTTP and gRPC is obvious.

[BenWhitehead]

Investigation into changing over to gRPC is underway and we hope to have a idea of the level of effort soon.

Any updates on when gRPC support will be available?

Is the old deprecated AppEngine api the only way for non-blocking calls?
