Anoop Sam John commented on HBASE-6942:
---------------------------------------
In order to support all types of deletes we need to have the params
cf names which needs to be deleted
qualifier names which needs to be deleted
timestamp im case we need a time based delete
a type - This is needed when it is a delete version request
The scan ideally need not scan all the column which needs to be deleted. If I
have a condition based delete, what needs to be scanned is the columns
involving in the condition..
So taking all these in another POJO, i thought it would be better to accept as
Delete object. In that we have APIs like deleteColumn(s), deleteFamily etc...
Users also might be very much knowing this. What do u say Lars? The bit weird
part I am seeing in this is the rowkey which need to be a fake one..
bq.We'd have to make up fake column qualifiers and qualifiers in the future
Sorry didnt get your mean
Thanks for the reviews and comments
