Question

我正在尝试使用批量加载程序功能将一个容易调整大小的csv文件上传到谷歌应用引擎，并且它看起来会因某些方式而导致以下结果：

[INFO    ] Logging to bulkloader-log-20110328.181531
[INFO    ] Throttling transfers:
[INFO    ] Bandwidth: 250000 bytes/second

[INFO    ] 1740 entites total, 0 previously transferred
[INFO    ] 720 entities (472133 bytes) transferred in 32.3 seconds
[INFO    ] Some entities not successfully transferred

它上传了我要上传的19k条目中的大约700条，我想知道它为什么会失败。我检查了csv文件是否有错误，比如可以抛弃python csv阅读器的其他逗号和非ascii字符已被删除。

提升批次限制（batch_size）和rps限制（rps_limit）有效，我使用1000作为批量大小，rps限制为500：

appcfg.py upload_data --url= --application= --filename=  --email= --batch_size=1000 --rps_limit=500
