/**
Creates a write batch, used for performing multiple writes as a single atomic operation. The maximum number of writes allowed in a single WriteBatch is 500.

Unlike transactions, write batches are persisted offline and therefore are preferable when you don't need to condition your writes on read data.

@returns
A WriteBatch that can be used to atomically execute multiple writes.
