WriteBatch(client)

Accumulate write operations to be sent in a batch. Use this over BulkWriteBatch for lower volumes or when the order of operations within a given batch is important.

This has the same set of methods for write operations that xref_DocumentReference does, e.g. xref_create.

Parameter

client	Client The client that created this batch.

Inheritance

Parameters

Name	Description
