Mark Miller commented on SOLR-8416:
-----------------------------------

bq. 1. The patch pulls shard status from zk and returns if they are all active 
during preset time or throw exception. An alternative is to wait for zk 
notifications but I am not sure how much is the gain.

I agree, the complication is probably not worth it.


bq. Is it good to be a solr config or collection config?

I would make it a solr config - we need that ease of use at least. Later, if 
someone wants to override per collection or something, we can look at adding 
that in a way that you can override.

> Solr collection creation API should return after all cores are alive

> Currently the collection creation API returns once all cores are created. In 
> large cluster the cores may not be alive for some period of time after cores 
> are created. For any thing requested during that period, Solr appears 
> unstable and can return failure. Therefore it's better  the collection 
> creation API waits for all cores to become alive and returns after that.
