ReaderReadUpTo
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Mengembalikan hingga pasangan `num_records` (kunci, nilai) yang dihasilkan oleh Pembaca.
Akan dikeluarkan dari antrean input jika diperlukan (misalnya ketika Pembaca perlu mulai membaca dari file baru karena telah selesai dengan file sebelumnya). Ini mungkin menghasilkan kurang dari `num_records` bahkan sebelum batch terakhir.
