------------------------------------
Resolution: Won't Fix
> Connector API : Ability for connector to indicate if its FROM and TO support
> incremental reading/ writing
> ---------------------------------------------------------------------------------------------------------

>
> No longer a necessity, If the connectors have delta read/ write configs we
> will display it and they will use those config values to do the appropriate
> form or reading from and writing to the data source. At this point having
> this in the initializer API does not seem necessary, we can revisit if we
> need this information upfront for any form of validation when the job is
> created.
> By default it is assumed the connectors will do a full fetch and full write
> from clean slate.
> For instance if the TO does not support delta records to be written is some
> fashion, but the FROM side only gave subset of records, we cannot expect
> delta append or merge ( overwriting existing records with no dupes) to
> happen.
