Description

During execution of Push Task, the following operation sequence is found:

1. read on External Resource to assess whether MATCHING or UNMATCHING rule is to apply
2. create and execute a Propagation Task - which will
   1. read on External Resource to decide for actual create or update
   2. read on External Resource afterwards, to check for the result
3. read on External Resource afterwards, for Audit / Reporting

It seems far from efficiency, round-trip should be reduced to 1 read before / 1 read afterwards.
