Maximum number of cores on a single Solr instance

[Uomesh <Uo...@gmail.com>]

Hi Solr Experts,

Could you please suggest how many cores we can have on a single solr
instance? support we have 8 slaves running in a load balancing enviornment,
can we have around 800 cores on each slave instance?

I saw a pending request SOLR-1293 which will support lots of core but that
is not yet fixed.

Thanks,
Umesh

There's really no way to answer your question.  It depends on resource 
availability (primarily I/O on disk and network, RAM, disk space) versus 
how much of those resources each core will consume.

Whether or not you can get 800 cores to perform well will depend on a 
lot of variables.  There are no inherent limitations in Solr that would 
prevent you from creating cores well beyond 800.

Thanks,
