Description
Includes all commits from https://github.com/DataDog/pomsky/pull/466 to implement the metrics indexing pipeline using parquet in quickwit.
The assumptions/decisions made in this PR (the parquet schema, etc.) are not final. We are merging this PR to set up the machinery for future PRs to build out the parquet write/read path in quickwit. The assumptions/decisions made here are going to change, so I wouldn't care too much about it. There are some things structure wise that are bad (such as putting
arrow_metrics.rsunderquickwit-opentelemetry/src/otlp), but we will address these later, I promise :)This PR has all Datadog specific code/metrics removed. Also, does not expose the OTLP metrics endpoint for ingestion. The parquet pipeline is all wired up, but it's a dead path - there's no way to send data through it.
