Hi, I am creating a custom druid metric column which will store a custom object and serialize it to a byte []. Size estimation is ~1KB. If within my ingestion spec i specify the metricCompression = lz4 (the default one), will the data in this particular custom metric column also get compressed? The documentation on this is a bit unclear because it says "Compression format for primitive type metric columns" https://druid.apache.org/docs/latest/ingestion/ingestion-spec/#indexspec
