Shai Erera updated SOLR-7325:
-----------------------------
Attachment: SOLR-7325.patch
Patch implements a basic change, in order to get some feedback first:
* Slice.State declares 4 values: ACTIVE, INACTIVE, CONSTRUCTION, RECOVERY. Are
these all the states or did I miss some?
* I documented these very briefly, mostly from what I understood from the code,
and some chats I had w/ [~anshumg]. I would definitely appreciate a review on
this!
* Slice.state is held internally as an enum, but still exposed as a String:
** Backwards-compatibility wise, is it OK if we change Slice.getState() to
return the enum? It's an API-break, but I assume it's pretty expert and the
migration is really easy.
** Note that it's still written/read as a String.
* I didn't yet get rid of the state constants:
** Is it OK to just remove them, or should I deprecate them like I did for
STATE?
In this issue I would like to handle Slice, and change Replica separately.
After I get some feedback, and if there are no objections, I'll move the rest
of the code to use the enum instead of the string.

>
> Slice state is currently interacted with as a string. It is IMO not trivial
> to understand which values it can be compared to, in part because the Replica
> and Slice states are located in different classes, some repeating same
> constant names and values.
> Also, it's not very clear when does a Slice get into which state and what
> does that mean.
> I think if it's an enum, and documented briefly in the code, it would help
> interacting with it through code. I don't mind if we include more extensive
> documentation in the reference guide / wiki and refer people there for more
> details.
