---------------------------------
Summary: Support non integer values for replica in autoscaling
rules
Key: SOLR-12511
URL: https://issues.apache.org/jira/browse/SOLR-12511
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Noble Paul
Assignee: Noble Paul
This means the user can configure a decimal value in replica
example :
{code:json}
{"replica": 1.638, "node":"#ANY"}
{code}
This means a few things. The no:of of replicas in a node can be either 2 or 1.
This also means that violations are calculated as follows
* If the replica count is 1 or 2 there are no violations
* If the replica count is 3, there is a violation and the delta is *{{3-1.638
= 1.362}}*
* if the replica count is 0, there is a violation and the delta is *{{1.638 -
0 = 1.638}}*
* This also means that the node with zero replicas has a *more serious*
violation and the system would try to rectify that first before it address the
node with 3 replicas
