Ejemplo

// In-memory para analisis temporal
db, err := DuckDBOpen("")
if err != nil {
    log.Fatal(err)
}
defer DBClose(db)

rows, err := DBQuery(db, "SELECT * FROM read_parquet('/data/sales.parquet')")

Notas

Usa el driver github.com/marcboeker/go-duckdb (CGO). DuckDB es una base de datos OLAP embebida, ideal para analisis de datos. Path vacio equivale a :memory:. Hace ping al abrir para detectar errores temprano.
