Andrzej Bialecki commented on SOLR-9947:
-----------------------------------------
bq. I don't think we should rush the naming on the eve of a feature freeze.
As I mentioned above, this mainly affects the new API, with a very limited
impact on the old API, so I think we should be fine. I'd rather make a couple
renames in the next release than to withhold the dozens of renames in this
patch that really make the new API much cleaner.
bq. how the patch retains both the old and new hierarchy
The same instances of {{SolrInfoMBean}}-s are registered under the old names
and new hierarchical names. This way we preserve the back-compat, and at the
same time we provide an alternative, improved view of the same information.
bq. though perhaps at the base level a generic simply HANDLER (I dunno).
Yeah, naming is hard :) On one hand it needs to be specific enough to be
informative, on the other hand it needs to be generic enough to limit the total
number of categories, and on the third hand ;) if it's too generic then it
becomes meaningless.
I discussed this with Shalin, we considered and rejected HANDLER, PLUGIN and
the like as too generic, after all all these components are handlers and
plugins. In the latest patch I moved quite a few components from QUERY to other
categories, leaving only those that actually support query-response interaction
with users.
