Solomon Duskis commented on BEAM-3342:
--------------------------------------

The Cloud Bigtable client is just about ready with full functionality.  It did 
indeed take longer that we were expected.  Once we do that, there's a 
likelihood that a Python write connector will significantly underperform 
compared to Java, since the Python client only performs synchronous operations, 
where the Java has a high throughput asynchronous writer.

Also, in terms of reading from Cloud Bigtable, any connector needs full support 
for a BoundedSource, or something like it.  We could not figure out how to make 
BoundedSource work in Python.
