Resolved by the `arreflect` package (`f63e2c65`), released in v18.6.0: https://pkg.go.dev/github.com/apache/arrow-go/v18/arrow/array/arreflect The workflow described here — go from a tagged Go struct to an Arrow schema and then populate a record without hand-writing per-field builder calls — is now: ```go sc, err := arreflect.InferSchema[Test]() // struct -> *arrow.Schema rec, err := arreflect.RecordFromSlice(objs, memory.DefaultAllocator) // []Test -> arrow.RecordBatch ``` This also removes the `pqschema.NewSchemaFromStruct` + `pqarrow.FromParquet` round-trip from the original example. Closing, and removing the `good-first-issue` label since the work is done. See also #44, closed for the same reason. -- This is an automated message from the Apache Git Service.
