Subject [jira] Commented: (CHUKWA-345) Chunk.application and Chunk.streamName are redundant
Date Wed, 04 Nov 2009 19:25:32 GMT


Eric Yang commented on CHUKWA-345:

+1 to commit this patch.

Serialization format and protocol format are somewhat coupled.  It's not possible to use certain
protocols if the serialization format uses the same keywords.  For example, GET / HTTP/1.0\r\n\r\n
maybe required to be escaped in serialization format, if Content-Length: is not honored, and
HTTP protocol is chosen to wrap around the serialization protocol.  The same escaping rules
apply to any transport protocol and serialization format.  Hence it's best to define the serialization
format and protocol upfront.  The implementation would be easier and less error prone.  However,
the protocol and serialization changes should not be in scope of this jira.

> The chunk interface has both an "application" field and a "stream name" field. But they
map to the same value.  Should cut one of those names, for clarity.
> I think "application" is the less descriptive name, and should be cut.
