Shalin Shekhar Mangar commented on SOLR-10665:
----------------------------------------------
Thanks Jan. I have a few comments:
# I think we should split up plugin system and plugin repositories features
into separate issues. The former can be designed and built without the latter.
# We should make it easy to build install custom plugins. Perhaps a maven
archetype might be useful to bootstrap custom plugin projects.
# SolrCloud presents its own challenges which aren't addressed by the design at
all:
## We shouldn't force people to deploy plugins by ssh'ing into each box and
restarting Solr
## As Noble said, every node must have the same binary. This must be enforced.
## Are plugins always cluster-level or should we have them on a per collection
basis thereby exposing certain plugins only to specific collections.
## I agree with Noble that we should consider enhancing blob store to deal with
this use-case.
# The framework must play well with the security API. Only authorized users
must be able to install/upgrade/remove plugins. There should be a separate
permission for these operations.
# The API can be called just /admin/plugins instead of /admin/pluginbundles

> Project: Solr
> Issue Type: New Feature
> Components: Plugin system

> In SOLR-5103 we have been discussing improvements to Solr plugin system, with
> ability to bundle a plugin as zip, and easily install from shell or Admin UI.
> This task aims to create a working POC to demonstrate how PF4J (Plugin
> Framework4J) can be used to bring a very simple plugin packaging and
> installation system to Solr with a minimum of effort. Code speaks louder than
> words :)
> The POC effort is a quite large patch and will be cutting some corners to get
> the feature in the hands of people who can test and evaluate. If there is
> consensus to add this to Solr, there will be other sub tasks to split up the
> elephant into committable chunks.
> The design document is located here: https://s.apache.org/solr-plugin (Google
> Doc) - comments are welcome in the document or here.
