hi all:
I'm reading phoenix src code recently, and i found
PRowImpl.toRowMutations() always adds an empty column named '_0' for non-delete
upsert. Why?
I read the comment but i didn't quite understand it. Might someone give me
an example that illustates why an empty column is ALWAYS necessary?
Further more, I have to access a phoenix table by both phoenix client and
hbase API in some cases. If i do not add this empty column explicitly by hbase
API, it is ok if i read this row by phoenix?
Thanks
