Description

Supporting entity groups similar to App Engine's (that is, allow rows to be part of a parent "entity group," whose key is used for routing instead of the row itself) allows several improvements:

• batches within an EG can be atomic across multiple rows
• order-by-value queries within an EG only have to touch a single replica even with RandomPartitioner
