Yonik Seeley commented on SOLR-6787:
------------------------------------
bq. what is the solution?
I'm pointing out the possible issues and why my gut fee was to not encourage
the use of this API. The answer is to develop a solid API if we want this
feature.
Another big issue off the top of my head (that would be much harder to catch
via testing):
A different searcher may be used by the sub-request than is used by the parent
request. That's going to cause all sorts of problems.
Also less likely, the schema can change and be different from parent to sub
request.
There's also the question of lost "context", and anything that may use that (I
see you use that to only do useParams once, for example. is that OK to do
again?)

> A special collection called .system needs to be created by the user to
> store/manage blobs. The schema/solrconfig of that collection need to be
> automatically supplied by the system so that there are no errors
> APIs need to be created to manage the content of that collection
> {code}
> #create your .system collection first
> http://localhost:8983/solr/admin/collections?action=CREATE&name=.system&replicationFactor=2
> #The config for this collection is automatically created . numShards for this
> collection is hardcoded to 1
> #create a new jar or add a new version of a jar
> curl -X POST -H 'Content-Type: application/octet-stream' --data-binary
> @mycomponent.jar http://localhost:8983/solr/.system/blob/mycomponent
> # GET on the end point would give a list of jars and other details
> curl http://localhost:8983/solr/.system/blob
> # GET on the end point with jar name would give details of various versions
> of the available jars
> curl http://localhost:8983/solr/.system/blob/mycomponent
> # GET on the end point with jar name and version with a wt=filestream to get
> the actual file
> curl http://localhost:8983/solr/.system/blob/mycomponent/1?wt=filestream >
> mycomponent.1.jar
> # GET on the end point with jar name and wt=filestream to get the latest
> version of the file
> curl http://localhost:8983/solr/.system/blob/mycomponent?wt=filestream >
> mycomponent.jar
> {code}
> Please note that the jars are never deleted. a new version is added to the
> system everytime a new jar is posted for the name. You must use the standard
> delete commands to delete the old entries
