## Ejemplo
|
|
|
|
```go
|
|
// 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.
