BigTable是否允许设置微时间戳粒度
Does BigTable allow setting micro timestamp granularity
我正在尝试将时间戳作为微粒度的单元格写入 Bigtable。此处的文档说我应该能够将粒度设置为微米：https://cloud.google.com/bigtable/docs/reference/data/rpc/google.bigtable.v2#google.bigtable.v2.Mutation.SetCell
但是如果您查看 java 客户端，我看不到除了 millis 之外的其他设置选项。 https://cloud.google.com/bigtable/docs/reference/admin/rpc/google.bigtable.admin.v2#google.bigtable.admin.v2.Table.TimestampGranularity
有谁知道是否可以将粒度设置为微米级？
If unspecified at creation time, the value will be set to MILLIS
看来您创建BigTable时需要将粒度设置为微米，除非，它会被设置为默认为毫秒。除此之外，如Package google.bigtable.v2 documentation, there is the function TimestampRangeFilterMicros that you can use with values in micros - more information in this BigTable documentation here.
中所述
如果这些信息对您有帮助，请告诉我！
我联系了 google，他们确认他们只支持以毫秒为单位设置单元格时间戳，即使时间戳在内部似乎存储为微秒。
这是他们的 C++ 库所说的
Cloud Bigtable currently supports only millisecond granularity in the
cell timestamps, both TIMESTAMP_GRANULARITY_UNSPECIFIED and MILLIS
have the same effect. Creating cells with higher granularity than the
supported value is rejected by the server.
