This release contains API changes. We strived for backwards compatibility with 0.1.0: code which compiled and ran against 0.1.0 should compile and run against 0.2.0 too. However, we may have broken code using AsyncIterator, which has been superseded by BatchIterator. There are methods to convert between the two.
This release contains on-disk format changes. We strived for backwards compatibility with 0.1.0: The 0.2.0 package can read all 0.1.0 formats, however the 0.1.0 package cannot read some 0.2.0 formats.
This release runs scans in batches from replica to client. This required switching from AsyncIterator, which operated on one element at a time, to BatchIterator. It also required using HTTP chunks, and that in turn required switching from Finatra to Finagle.
