I have been using
Git/Gerrit for about 9 months and I still don't know the
answer to this question. (c.f. Gerrit Documentation )
Gerrit, when a change is pushed for review, there will be an URL about the change with an embedded number. For example:
What is the official name of this number? (
68 in the above example). This number is an important concept when discussing the Gerrit workflow.
On the Gerrit UI, this number may also shown on the upper left-hand conner. Something like:
Change 68 - Merged
The number is a small integer that seems to increase monotonically when pushes are submitted to the Gerrit server.
This number should NOT be confused with "Change-Id" because the latter is a long hash (prefixed by the letter
I) used to identify multiple related pushes (created with one
commit followed by one or more
commit --amend) into one "Change" (which can have one or more "Patch-Set") . E.g:
