Lou DeGenaro commented on UIMA-3857:
------------------------------------
Code delivered.
OR now keeps a file state/orchestrator.json comprising sequence numbers for
State and AbbreviatedState publications.
This file can be erased when doing cold or warm starts, but should be kept when
doing hot (re-)start or Orchestrator.
> DUCC Orchestrator (OR) should should checkpoint and restore publication
> sequence number.

> of these OR publications may reject them as being out-of-sequence.
