> We should consider changing the timeline annotations in Span.java to be a
> map<string, string> rather than a map<byte[], byte[]>. It's very
> inconvenient to deal with byte arrays here, and every use-case we have
> currently puts string data into these fields. One example is that you cannot
> look up fields in the map, since the map<byte[], byte[]> compares by byte
> array object equality (useless unless you have the original key array object
> you inserted). It's also questionable if we could put non-string data in
> this map at all, since we are serializing them to JSON strings, which can't
> handle arbitrary byte strings.
