Hi Ming,
Thanks for reaching out to the Google Ads API Forum.
With regard to your concern, note the historical & forecast metrics, it does not have operations, but it is planning services. However, BatchJobService supports operations that are listed in MutateOperation here only. For more information on BatchJob, you may refer to this page.
As a side note, all requests to Keyword Planning services for both standard and basic access are rate limited. Fewer requests are allowed per minute when compared to other services. Our recommendation is to cache or store results as you will receive the same response over a long time span. For example, if you request a set of existing keywords, the response is not going to change over a period of hours or days. In the case of historical metrics, the statistics refresh monthly.
Let us know if you have any additional questions.
Regards,
