SpannerIO trying to read all the table

[SaurabhSingh92]

Hi Team,

We have been planning to use dataflow with spanner, while doing POC i noticed the SpannerId.read was trying to read complete table.
Resulting more time in processing, can we make it like it keeps dropping batch of data already reading like we do in window?
