Make gRPC supports pipeline #7343
Description
What problem does the new feature solve?
Currently the pipieline processing engine only supports http endpoints such as Promethes Remote Write, Loki and /logs etc.
But in the gRPC ingestion, it also needs some lightweight ETL processing.
What does the feature do?
Make the gRPC ingestion supports pipeline:
- if the pipeline header is provided, processes the data by pipeline and ingests the transformed data instead.
Implementation challenges
Looks like it's not hard to implement this feature.
