Is there any way to pack DDP Sub in one socket message, not many?

[dospolov]

I have a lot of small docs in collection. I need to fetch it on the client.
If I’m using pub/sub each doc transfered via separate socket message.
Is there any way to pack DDP Sub in one socket message, not many?

I can do it with meteor call, but is there any mechanism in Pub/Sub for that?

Yes possible with Meteor 1.3.3.

1.3.3 beta w/ DDP Batching now available!

Hey all, We’ve just pushed a beta release including a larger change that will land in 1.3.3: DDP batching. To upgrade to the release, run: meteor update --release 1.3.3-ddp-batching-beta.0 From History.md: DDP callbacks are now batched on the client side. This means that after a DDP message arrives, the local DDP client will batch changes for a minimum of 5ms (configurable via bufferedWritesInterval) and a maximum of 500ms (configurable via bufferedWritesMaxAge) before calling any callback…

That’s not the same thing - that’s about delaying reactivity while data is coming in. I’m pretty sure @dospolov is talking about “packing” a number of DDP frames into a larger DDP frame to improve transaction throughput.

@robfallows, yeap, you’ve got the point
