Tell us about the problem you're trying to solve

When specifying a Dataset_id, the Google UI often includes the project_id in its naming like this: project_id:dataset_id

Describe the solution you’d like

In the BigQuery destination code, we could accept both syntax:

• project_id:dataset_id
• dataset_id

So it's smoother for the end user whether project_id is specified or not?

Create a MongoDB benmchmark and compare it with other existing integrations.

I am working with an Odata API interface which presents timestamp values such as lastModified in a format similar to `//Date(1530144000000+0530)/. Would it be possible to get such date formats supported. If this is something that could be supported I'd be happy to contribute this sort of functionality, a steer in the right direction would certainly be appreciated.

I believe that both the tone (using the first person in some places) and the links (e.g. line 23) should be adapted to our specific project.
