> Key: SOLR-14613
> URL: https://issues.apache.org/jira/browse/SOLR-14613
> Project: Solr
> Issue Type: Improvement
> Components: AutoScaling
> Reporter: Andrzej Bialecki
> Priority: Major
> Time Spent: 10h 10m
> Remaining Estimate: 0h

> 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.
