Alfonso Nishikawa updated GORA-207:
-----------------------------------
Attachment: GORA-207_over_r1465660.patch
Uploaded last patch for this issue: GORA-207_over_r1465660.patch
What this does is write the top level fields of a record (the outermost, not
nested ones) as following:
If schema = ["null","type"] => write as ["type"]
else => write serialized as usual.
I dumped the "optional configuration, blah, blah, blah" because it was
introducing really innecessary complexiny. No one should want to have the
behavior "always serialized", I expect.
ONE BIG PROBLEM:
The solution assures compatibility of data with Nutch's WebPage schema being
updated making top level fields optionals, but it is not possible to make
compatible nested data :(
The solution is much dirty; too much dirty. I will have to write about and we
should vote :\
It is impossible to make compatible nested schemas (I guess almost no one used
in that way) with it's fields being converted to optional (+null type).
If people don't change their schemas, no bad things will happen :)
Any comments about? if no, I will commit and close this issue (GORA-207)
