fromProto(MutateRowsRequest request)

public static BulkMutation fromProto(MutateRowsRequest request)

Wraps the protobuf MutateRowsRequest.

This is meant for advanced usage only. Please ensure that the MutateRowsRequest does not use server side timestamps. The BigtableDataClient assumes that mutation present in BulkMutation are idempotent and is configured to enable retries by default. If serverside timestamps are enabled then that can lead to duplicate mutations.

WARNING: when applied, the resulting mutation object will ignore the project id and instance id in the table_name and instead apply the configuration in the client.
