Noble Paul commented on SOLR-8349:
----------------------------------
Thanks. the tests are fine. But for one thing,
The blob store is not guaranteed to be available at core load time (the
{{.system}} collection ). So , your component should implement
{{BlobStoreAware}} and only in the callback for that interface , the class
should try to load resources
> Allow sharing of large in memory data structures across cores

> In some cases search components or analysis classes may utilize a large
> dictionary or other in-memory structure. When multiple cores are loaded with
> identical configurations utilizing this large in memory structure, each core
> holds it's own copy in memory. This has been noted in the past and a specific
> case reported in SOLR-3443. This patch provides a generalized capability, and
> if accepted, this capability will then be used to fix SOLR-3443.
