BigQuery Python: imibuzo iyasebenza ngokusebenzisa i-proxy, ukulanda kuyahluleka
Hlola ukuthi ukulanda komphumela we-BigQuery Python kwakha i-Storage API client ezimele endleleni ye-HTTP yombuzo.
Umbuzo ungaphothula ngempumelelo kodwa wehluleke lapho ulanda umphumela wawo ku-pandas. Umtapo wezincwadi we-BigQuery Python ungasebenzisa i-BigQuery Storage API client ehlukile kulokho kulanda.
I-interface ye-RowIterator.to_dataframe ibhala i-create_bqstorage_client, okuyisimo sayo esizenzakalelayo singu-true, kanye ne-argument ye-bqstorage_client. Funda lezo zilungiselelo kanye nokuncika okukhona kuhlelo lokusebenza. Impumelelo endleleni evamile yombuzo akufakazeli ukuthi ukuthutha okukhethiwe kokulanda kunokwesekwa kwe-proxy noma ukucushwa okufanayo.
| Isigaba | Okumele kuhlolwe |
|---|---|
| Ukutholwa kobufakazi | Ukuthuthwa kobufakazi kanye ne-endpoint yobunikazi |
| Ukuthumela nokuphola umbuzo | Indlela yesicelo se-BigQuery client |
| Ukulanda nge-Storage API | I-Storage API client nokuthuthwa kwayo |
Ukuze kuqhathaniswe okulawulwayo, inketho ebhaliwe i-create_bqstorage_client=False igwema ukwakhiwa okuzenzakalelayo kwalelo client elengeziwe. Lokhu kungasiza ukukhomba ukuthi iyiphi indlela ehlulekayo. Kuwukukhetha kokuthutha okunemithelela yokusebenza, hhayi ubufakazi bokuthi i-proxy ngokwayo yalungiswa.
Uma uhlelo lokusebenza luhlinzeka nge-Storage API client yalo, lungiselela lelo client ngamabomu. Ungacabangi ukuthi into ye-HTTP yangokwezifiso exhunywe kwelinye i-client izoyilungiselela kabusha.
Izibonelo ezindala zikhuluma ngezimo ze-httplib2 eziphelelwe yisikhathi noma ama-hook e-constructor ayimfihlo. Fanisa ukuhlanganiswa nesizukulwane somtapo wezincwadi ofakiwe, futhi gcina isigaba sokwehluleka embikweni. Iphutha lokuguqulwa kwe-DataFrame nokuxhumana kwenethiwekhi okunqatshiwe kuyimiphumela ehlukile ngisho noma kwenzeka ocingweni olulodwa lwendlela.
