We were discussing which plugin to use for v3 core and decided to use http plugin before this PR gets merged and did a bit of code analysis with Claude in case it is helpful (thank you for working on this plugin):

@lumaks-redox I'm not sure what you are trying to say... The v3 API documentation states that partial-writes is true by default. Is this your concern?

I was trying to say that for now, we have to use http plugin to be able to use V3 api with partial writes support, but http plugin lacks all backoff retry and other goodies from influx_v2 plugin, so I am happy to see that influx_v3 plugin you are working on will support both the partial writes and all the retries functionality, and was just sharing my findings in case you missed some functionality (I think you didn't).
