Is there an ETA for this? We prepared a similar implementation to make our functions idempotent and we're planning to apply on a bunch of our systems. But we'd rather adopt the one coming from power-tools than our homemade version; they look pretty similar.

Also would it be possible to emit some metrics around number of requests de-duped, various error counts etc.?

@jeromevdl has started looking into it.

This can be an interesting thing to support. @heitorlessa What do you think? Has it been discussed for python one?
