Ishan Chattopadhyaya commented on SOLR-14613:
---------------------------------------------

bq. Assign.createAssignStrategy() picks between existing placement strategies 
and the new plugin one.
Why can't "existing placement strategies" also be a "plugin" (even if it 
available as default). Why any distinction between default and custom placement 
strategies?

> As described in SIP-8 the current autoscaling Policy implementation has 
> several limitations that make it difficult to use for very large clusters and 
> very large collections. SIP-8 also mentions the possible migration path by 
> providing alternative implementations of the placement strategies that are 
> less complex but more efficient in these very large environments.
> We should review the existing APIs that the current autoscaling engine uses 
> ({{SolrCloudManager}} , {{AssignStrategy}} , {{Suggester}} and related 
> interfaces) to see if they provide a sufficient and minimal API for plugging 
> in alternative autoscaling placement strategies, and if necessary refactor 
> the existing APIs.
> Since these APIs are internal it should be possible to do this without 
> breaking back-compat.
