Specify the Cosmos container to read from.

withQuery

public CosmosIO.Read<T> withQuery(String query)

Specify the query to read data.

withCoder

public CosmosIO.Read<T> withCoder(Coder<T> coder)

expand

public PCollection<T> expand(PBegin input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
