      Work Description: thiagotnunes opened a new pull request #16467:
URL: https://github.com/apache/beam/pull/16467


   Adds the DetectNewPartitions SDF. This component will be responsible for:
   
     - Emitting a watermark based on the min of all unfinished partitions in 
the metadata table.
     - Querying all partitions in the CREATED state.
     - Updating the created partitions to SCHEDULED state.
     - Emitting the scheduled partitions to the PCollection.
   
   This SDF will run periodically as based on the configured resume interval 
(default is 100ms, best effort).
   
   Adds the full class of all the metrics that we might expose from the 
Connector.

> We would like to augment the existing Google Cloud SpannerIO connector 
> ([https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/spanner/SpannerIO.java)]
>  with the support for Spanner Change Streams (CDC). CDC support is just being 
> implemented in Spanner and it will be exposed through a gRPC API. We will use 
> such API to create a new SpannerIO.readChangeStream(...) implementation.
