Subject [jira] [Commented] (SOLR-2567) Solr should default to TieredMergePolicy

Then I saw that there would be some side affects to that based on this patch? I didn't really
look closely, but from memory, I guess it would disable being able to set compound file? And
you wouldn't be able to change the tiered policies settings? Or does Solr's config any given
method voodoo work in this case?

Right, this is definitely a downside to not having this patch, they cannot set compoundFile
or mergeFactor. 

And you are also right about tiered policy settings... you will notice I didn't actually enable
these in the patch. I guess thats because I thought it would be confusing to add "MP-specific"
settings all piled in to the config. I was planning on opening another issue for this to allow
for a factory configuration like other things, especially so I can pass a 'long' random seed
so that tests can use MockRandomMergePolicy :)
