ivankelly opened a new pull request #1866: Binary metadata format
URL: https://github.com/apache/bookkeeper/pull/1866
 
 
   This patch adds a binary metadata format and bumps the metadata format
   version to 3. The contents of the binary metadata is the same as the
   contents of the text format for now. The difference is that the binary
   is more compact, and the fields can be added to the metadata when
   using the binary format, which isn't possible with the text
   format. With the text format, parsing with a client that didn't
   recognise the new field would fail.
   
   For now, the text format (version 2) is still used by default. We will
   provide a tool to allow administrators to bump to version 3.
   
   Some tests have been modified to provide digest and password to the
   builder. All protobuf metadata in released versions has had digest and
   password (first protobuf metadata was in release-4.2.0). So if new
   metadata is created or read with version 2, it will have this two
   fields set.
   
   Master issue: #723
