Shawn Heisey commented on SOLR-4793:
------------------------------------

bq. Hmm, I don't think we should be starting with this kind of magic

If there are still things to work out with the blob store (this is the .system 
collection, right?) then I agree, we should let those things bake for a while 
before we implement automagic redirection from ZK.  I do like Jan's idea, 
though.

> Zookeeper set znode size limit to 1MB by default. So we can't start Solr 
> Cloud with some large config files, like synonyms.txt.
> Jan Høydahl has a good idea:
> "SolrCloud is designed with an assumption that you should be able to upload 
> your whole disk-based conf folder into ZK, and that you should be able to add 
> an empty Solr node to a cluster and it would download all config from ZK. So 
> immediately a splitting strategy automatically handled by ZkSolresourceLoader 
> for large files could be one way forward, i.e. store synonyms.txt as e.g. 
> __001_synonyms.txt __002_synonyms.txt...."
