是否可以按摄取时间对按摄取时间分区的 BQ 表进行聚类？
[英]Is it possible to cluster by Ingestion Time a BQ table partitioned by Ingestion Time?
问题描述
We currently use a BQ table partitioned by day on a column date1 and clustered by the same date column date1 .
我们目前使用 BQ 表，该表在列date1 date1 。 This enables us to optimize our costs.这使我们能够优化成本。 However, we would like to use the tables partitioned by ingestion time instead but I haven't found if it was possible to also cluster by _PARTITIONTIME.但是，我们想改用按摄取时间分区的表，但我还没有发现是否也可以按 _PARTITIONTIME 进行聚类。
Does anyone know if we can do such thing in BigQuery?有谁知道我们是否可以在 BigQuery 中做这样的事情？
Thanks for your help谢谢你的帮助

From a recent release, BigQuery clustering is independent of the partitioning .从最近的版本开始，BigQuery 集群独立于分区。 Therefore, there is no limitation with (or without) ingestion time partitioning.因此，没有（或没有）摄取时间分区的限制。 I did a test and it worked great我做了一个测试，效果很好
