In JavaScript / on the web I can batch promises. await Promise.all([call1(), call2(), call3()]); Is there something equivalent in Rust and on the IC to perform multiple call in parallel? I would like to query the status of multiple canisters not in a row but, in a single batch. // Something like…

RTFM David, Rust noob question :sweat_smile:. Kind of: join === Promise.allSettled try_join === Promise.all use futures::join; use ic_cdk::api::management_canister::main::{ canister_status, CanisterIdRecord, CanisterStatusResponse, }; use ic_cdk::export::candid::{candid_method, export_servic…

It does seem like you might need some kind of IC specific implementation here. I run into issues where if I don’t know wait after so many futures in motoko that I run out of the cycle limit. Usually I batch them in groups of nine. I don’t do much rust, so I’m not sure how that works there, but I wou…

Good input, thanks for the share! Indeed probably same limitation, join_all takes a vector as parameter so I’ll try to batch them too.

I find this thread helpful Can I run multiple inter-canister update calls in parallel? - #2 by free.
