There is some documentation, however it’s buried under the Package Management: https://solr.apache.org/guide/solr/latest/configuration-guide/package-manager-internals.html#package-store
In https://issues.apache.org/jira/browse/SOLR-16038 there was some great work to start breaking out the File store from being tightly coupled to Packages. We do need better docs about the File store API in the ref guide, as I think that even in the 9.5 release we still refer to it as "Package Store APIs”. > On Jan 29, 2024, at 5:59 AM, Alessandro Benedetti <a.benede...@sease.io> > wrote: > > Do we have any documentation about the File store APIs current usages? > Is there any plan to replace SolrResourceLoader with that? > Learning To Rank uses the SolrResourceLoader mechanisms to load the model > into memory (to then use it) and that mechanism is used across many Apache > Solr functionalities and all of them require a collection reload to refresh > the resource: > https://solr.apache.org/guide/solr/latest/configuration-guide/managed-resources.html#applying-managed-resource-changes > > Changing this won't be trivial and If anyone approaches the problem I don't > think this should change for Learning To Rank only. > > Cheers > > -------------------------- > *Alessandro Benedetti* > Director @ Sease Ltd. > *Apache Lucene/Solr Committer* > *Apache Solr PMC Member* > > e-mail: a.benede...@sease.io > > > *Sease* - Information Retrieval Applied > Consulting | Training | Open Source > > Website: Sease.io <http://sease.io/> > LinkedIn <https://linkedin.com/company/sease-ltd> | Twitter > <https://twitter.com/seaseltd> | Youtube > <https://www.youtube.com/channel/UCDx86ZKLYNpI3gzMercM7BQ> | Github > <https://github.com/seaseltd> > > > On Mon, 29 Jan 2024 at 03:46, rajani m <rajinima...@gmail.com> wrote: > >> Thank you Ishan, here is the jira - SOLR-17132 >> <https://issues.apache.org/jira/browse/SOLR-17132>.
