David Smiley commented on SOLR-13661:
-------------------------------------
There are a few particular things I'm not sure I've seen here yet that I want
to ensure _could be supported_ (i.e. without major redesign/rework).
(1) Declare plugin/package dependencies for the whole configSet, such as via
additional options to solrconfig.xml "<lib>" tags. While this would not work
with hot deployment of plugins since a core reload is needed, this would at
least support the entire range of plugin interfaces we have that work from
within a SolrCore, and thus support all of the schema as well _without_ making
users add new tags to all these various elements.
(2) Use the new blob store for _resources_ (data) as an alternative to the
configSet. The configSet lives in ZooKeeper and as-such is a poor fit for,
say, machine learning models, language models, or any other large immutable
files needed within a running SolrCore. Such resource data might be versioned
like plugins but would be considered data and not code. Plugins could declare
dependencies on resources, or might be declared directly by the configSet in
some manner. Detaching from the configSet is also good for re-use of large
files across configs. I could imagine a SolrResourceLoader that interprets
special prefixes like "blob://mymodel/foo.dat" or some-such to generically plug
into our existing resource spots.
(3) Pluggable blob store implementation and/or support for a shared file system
across the cluster with a configurable path.
