Mutator Question: Is it possible to partition by ingestion time?

[lionkeng]

From the changes made in #113, it looks like the column identified for partitioning that the mutator cli takes has to exist. What I'd like to do is to actually partition the table by ingestion time (https://cloud.google.com/bigquery/docs/partitioned-tables#ingestion_time). This is a pseudo column named _PARTITIONTIME. Can this be supported?

Hi Keng Lim (@lionkeng) , apologies for the long silence about your question.

You can create a table by specifying the load_tstamp column as the partitioning column. This column will be automatically added to the table, ie it doesn't need to exist in advance.

Would that help?
