There was a problem hiding this comment.
Based on the original issue:
This project is capable of representing DataFusion metrics in a protobuf format, and at the same time, all DataFusion plans can be serialized as well, so it should be possible for this project to provide a loggable compressed EXPLAIN ANALYZE-like representation that is suitable for a logging system + the tools for properly decoding and visualizing that.
We do not want to just compress the EXPLAIN ANALYZE string in base64, what we want is to create a representation of the metrics as protobuf-compatible structs, and serialize/deserialize those instead.
