Mike Drob commented on SOLR-7280:
---------------------------------
{code}
- public int getCoreLoadThreadCount() {
- return coreLoadThreads;
+ public int getCoreLoadThreadCount(int def) {
+ return coreLoadThreads == null ? def : coreLoadThreads;
}
{code}
It might make sense for this to look like this instead:
{code}
public int getCoreLoadThreadCount(boolean zkAware) {
return coreLoadThreads == null ? (zkAware ?
DEFAULT_CORE_LOAD_THREADS_IN_CLOUD : DEFAULT_CORE_LOAD_THREADS) :
coreLoadThreads;
}
{code}
That was the standalone v cloud logic doesn't have to leak out as much.

> In SOLR-7191, Damien mentioned that by loading solr cores in a sorted order
> and tweaking some of the coreLoadThread counts, he was able to improve the
> stability of a cluster with thousands of collections. We should explore some
> of these changes and fold them into Solr.
