Roadmap to add more features?

[spacewander]

Currently, this extension already supports:

• process HTTP request
• send local response
• get HTTP request headers
• modify HTTP request headers
• get HTTP request body
• set HTTP request body
• process HTTP response
• get HTTP response headers
• modify HTTP response headers
• get all / set HTTP trailers
• get HTTP response body
• set HTTP response body

According to the proxy wasm spec, more features can be implemented. For example:

• run Go when Envoy starts as a bootstrap extension
• get/set Envoy property
• interact with Go filters run in different workers via the shared data/queue
• define/record metric

Will there be a plan to implement those features?

run Go when Envoy starts as a bootstrap extension

This could be useful, but we are pushing this extension into envoy official repo: pull request 22573
(BTW, the new changes will also push envoy, after it is merged)
There is no bootstrap extension, according to Matt's requirement.

So, it may be delayed.

interact with Go filters run in different workers via the shared data/queue

I have no idea about the shared data/queue. could you help to give some points for refers?

get/set Envoy property
define/record metric

Yeah, these are planned, PRs welcome.

But, not a full detailed todo list yet.

I think about it again. We don't need it because unlike the Wasm filter, the data in Go filter is already shared between worker threads.
