Otis Gospodnetic commented on SOLR-1293:
----------------------------------------
Do you have any thoughts on handling the situation where each core belongs to a
different party and each party has access *only* to its own core via Solr Admin
(i.e. doesn't see all the other cores hosted by the instance)? Only the
privileged administrator user can see and access all cores.
Have you done any work in on this or is this on your TODO?
> Support for large no:of cores and faster loading/unloading of cores

>
> Solr , currently ,is not very suitable for a large no:of homogeneous cores
> where you require fast/frequent loading/unloading of cores . usually a core
> is required to be loaded just to fire a search query or to just index one
> document
> The requirements of such a system are.
> * Very efficient loading of cores . Solr cannot afford to read and parse and
> create Schema, SolrConfig Objects for each core each time the core has to be
> loaded ( SOLR-919 , SOLR-920)
> * START STOP core . Currently it is only possible to unload a core (SOLR-880)
> * Automatic loading of cores . If a core is present and it is not loaded and
> a request comes for that load it automatically before serving up a request
> * As there are a large no:of cores , all the cores cannot be kept loaded
> always. There has to be an upper limit beyond which we need to unload a few
> cores (probably the least recently used ones)
> * Automatic allotment of dataDir for cores. If the no:of cores is too high al
> the cores' dataDirs cannot live in the same dir. There is an upper limit on
> the no:of dirs you can create in a unix dir w/o affecting performance
