Jesse Yates commented on PHOENIX-1241:
--------------------------------------

Yeah, byte[] was nice in a general sense, but most ppl want to store strings so 
we definitely saw cases where deserialization of the byte[] led to a garbled 
tag/annotation :-/

Here you could "cheat" and just say that, for instance if the byte[] is 
prefixed by 0x00,0x00 the next info is the type info, followed up the info; 
otherwise, the byte[] is just stored as a string. Or something like that.

> Currently traces only support storing string valued annotations - this works 
> for known trace sources. However, phoenix will have trace annotations with 
> specific types. We can improve the storage format to know about these custom 
> types, rather than just storing strings, making the query interface more 
> powerful.
> See PHOENIX-1226 for more discussion
