[GitHub] [beam] damccorm opened a new issue, #20767: SpannerIO.read() parallelism limited by partition count

damccorm opened a new issue, #20767:
URL: https://github.com/apache/beam/issues/20767

   Setting the partition size / count is not possible: 
   ```
    Note: This hint is currently ignored by sessions.partitionQuery and sessions.partitionRead requests.
   ```
   
   https://cloud.google.com/spanner/docs/reference/rest/v1/PartitionOptions
   
   Adding a Reshuffle might be the only choice, but it adds time and resource usage.
