RPC, `using`, Experimental Wrangler and Observability
When making RPC calls through a Service Binding, it's recommended (https://developers.cloudflare.com/workers/runtime-apis/rpc/lifecycle/#how-to-use-the-using-declaration-in-your-worker) that we employ the
using keyword to enable automatic cleanup. To use this, we're forced to use the wrangler@using-keyword-experimental version so that the using keyword is transpiled properly upon deployment. Unfortunately, this version of wrangler seems to be incompatible with the new observability setting that's available to us in wrangler 3.78.6.
Is there another way to handle RPC call cleanup without using the using keyword so that we can not bump into incompatibility with new features that are released?9 replies

Serialized RPC arguments or return values are limited to 1MiB
When trying to move to a Service Binding oriented architecture between workers, I bumped into the following error:
Serialized RPC arguments or return values are limited to 1MiB
This is happening when trying to transmit a large dataset through a service binding to the worker that handles DB operations. The array of data (trimmed as much as possible to an array of arrays) is just over 1 MB in size.
It feels strange that I may need to break this data up into multiple RPC calls to get past this limitation when doing it over HTTP worked just fine.
1. Is it possible to up this limit for a worker?
2. Do I have other options?
Thanks!5 replies

Tail Workers and Additional Event Data
Is it possible to add additional data to events passed to a Tail Worker? For instance, I have multiple workers stitched together with a unique
UUID. For instance, a scheduled worker kicks off and generates a UUID and sends messages to a queue consumer with the UUID as part of the message body. That queue also generates console.log messages. So, I've got two workers that are dealing with a single UUID and I'd like to use that data in my Tail Worker.
Is there a way to add the UUID to something that will have it bubble up into the TailItems object? Otherwise, I need to add the UUID into the console.log messages and parse them out. It would be nice if extra metadata could be added to the TailItems's event node.
Is this possible in any way?1 replies
