> Currently there is not stream metadata structure and log segment metadata is a customized
string structure. it would be good to use any IDL like thrift, protobuf to store the metadata
like what bookkeeper is doing.
> The reason to choose protobuf is
> - because bookkeeper is using protobuf, it is okay to use same stuff.
> - the thrift version that DL is using is a bit too old and hard to bump because it seems
the version is customized for finagle. using protobuf is easier to support other language
clients.
