handling in config service
discard 44b8cd26a1 Fix: - Accord Journal purging was disabled - remove
unique_id from schema keyspace - avoid String.format in Compactor hot path -
avoid string concatenation on hot path; improve segment compactor partition
build efficiency - Partial compaction should update records in place to ensure

new de9925f81a fixing post-rebase checkstyle problems
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (7be53d514e)
\
N -- N -- N refs/heads/cep-15-accord (de9925f81a)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 118 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.
