The parent shard will never be delete/clean?
Hi,
If I split shard1 to shard1_0,shard1_1， Is the parent shard1 will
never be clean up？
Best,

Solr 7.4.0 added a periodic maintenance task that cleans up old inactive parent shards left after the split. “Old” means 2 days by default.

Hi,
You might want to check out the documentation, which goes over
split-shard in a bit more detail:
https://lucene.apache.org/solr/guide/7_6/collections-api.html#CollectionsAPI-splitshard
To answer your question directly though, no. Split-shard creates two
new subshards, but it doesn't do anything to remove or cleanup the
original shard. The original shard remains with its data and will
delegate future requests to the result shards.
Hope that helps,
Jason
