Reference documentation and code samples for the Google Bigtable v2 API class PrepareQueryResponse.
Response message for Bigtable.PrepareQueryResponse
The time at which the prepared query token becomes invalid.
A token may become invalid early due to changes in the data being read, but
it provides a guideline to refresh query plans asynchronously.
