executionTime property
The time at which the results are valid.
This is a (not strictly) monotonically increasing value across multiple
responses in the same stream. The API guarantees that all previously
returned results are still valid at the latest execution_time. This
allows the API consumer to treat the query if it ran at the latest
execution_time returned. If the query returns no results, a response
with execution_time and no results will be sent, and this represents
the time at which the operation was run.
Implementation
core.String? executionTime;
