Does Solr master/slave support shard split
Hi,
Does Solr support shard split in the master/slave setup. I understand that
there is no shard concept is master/slave and we just have cores but can we
split a core into two.
If yes is there way to specify new mapping based on the unique key.

Thanks Eric. Moving to SolrCloud for splitting is what I too imagined 😐

In a word, “no”. It’s a whole ’nother architecture to deal
with shards, and stand-alone (i.e. master/slave) has no
concept of that.
You could make a single-shard collection in SolrCloud,
copy the index to the right place (I’d shut down Solr while
I copied it), and then use SPLITSHARD on it, but that implies
you’d be going to SolrCloud.
Best,
Erick
