Zbiorcze przesyłanie do obiektów blob w usłudze Azure

Question

Mam około 10 000 obrazów i muszę je przesłać do magazynu BLOB. Czy są jakieś narzędzia do przesyłania zbiorczego? Jestem również otwarty na pisanie własnego wniosku.

Answer 1

Spójrz na ClumsyLeaf cloud explorer. Prześlijmy pliki do bloba jak klient FTP. Alterntaive Azure Storage Explorer. Ten sam pomysł.

Obie pozwalają wybierać pliki z katalogu i przesyłać je za jednym razem. Nigdy nie próbowałem z 10 000, ale powinno działać.

Answer 2

Cloud Storage Studio też jest całkiem niezłe.

http://cerebrata.com/Products/CloudStorageStudio/

można uzyskać bezpłatną wersję próbną 30 więc żadnego ryzyka. Zwłaszcza jeśli jest to umowa jednorazowa.

Answer 3

Możesz użyć programu Windows Azure, aby przesłać/pobrać wiele plików z pamięci masowej.

Aby przesłać wiele plików, można użyć następującego wiersza polecenia.

ls -File -Recurse | Set-AzureStorageBlobContent -Container upload 

Aby pobrać wiele obiektów blob, można użyć następującego wiersza polecenia.

Get-AzureStorageBlob -Container containername -Blob blobname | Get-AzureStorageBlobContent

Answer 4

Odkryłam, że istniejące narzędzia są albo payware lub powolny dzięki zastosowaniu kilku wątków. TBH nawet płatne aplikacje próbowałem były dość powolna, ale Azure API jest bardzo proste, więc skończyło się na piśmie własne narzędzia wiersza poleceń, to się nazywa azupload:

https://github.com/bviktor/azupload

To nic nie kosztuje, wydany w ramach Licencja MIT. Posiada zarówno wersję C#, jak i Java, dzięki czemu można ją łatwo zainstalować zarówno w systemie Windows, jak i Linux.

Wersja C# używa wewnętrznego programu planującego .NET do rozpoczynania nowych wątków (zwykle jest to 10-ki na moim komputerze), podczas gdy wersja Java uruchamia tyle wątków, ile podałeś. Jest dość wydajny, testowałem go z 700 obrazami (łączny rozmiar 20 MB) i 100 wątkami, zakończył przesyłanie ich w 8 sekund.

Oczywiście musisz znaleźć równowagę. Jeśli zaczniesz zbyt wiele wątków, zwolni to z powodu narzutów maszyny wirtualnej Java. Ponadto, jeśli przesyłasz duże pliki, wysyłanie na 100 wątków nie ma większego sensu, ponieważ w tym przypadku wąskim gardłem będzie przepustowość, a nie obciążenie transakcyjne, jak w przypadku wielu małych plików. Ponadto, jeśli prześlesz wiele plików, JVM otworzy pliki szybciej, niż może je zamknąć, więc po chwili dostaniesz wyjątki od Too many open files (dla mnie, co się stało z plikami 13k @ 100 wątków). Z reguły im mniejsze pliki, tym więcej wątków, ale prawdopodobnie powinieneś zatrzymać się w okolicach 50.

Twoja opinia jest bardzo doceniana!
