This looks good to me as the initial pass, pinging @djaglowski to take a look.

Thanks for taking this on!

Generally looks good to me. I recognize this is a preliminary commit but I used the opportunity to give it a closer look. My feedback can be set aside for future PRs if there's a preference to have a cleaner copy of the original source.

I wanted to get a approval from @BinaryFissionGames at this PR is on their behalf. After that I also have some suggestions.

I'm happy to address your feedback either in this PR or in subsequent PRs so we can make more isolated changes.

@djaglowski I think I've addressed all the immediate feedback and created tracking issues for the others:

• [processor/logdeduplication] Use OTTL for field syntax selectors #34473
• [processor/logdeduplication] Review processor shutdown behaviour #34478

Feel free to assign these to me.
