Subject Re: [jira] [Commented] (SOLR-3816) Need a more granular nrt system that is close to a realtime system.

Radim:

Do you mean branch 4x (as opposed to 4.0) or trunk (5.x)?

soft-commit offers NRT and is more realtime friendly than hard commit but is limited by the
dependency on the SolrIndexSearcher being closed and reopened and offers a coarse granular
NRT. Closing and reopening of the SolrIndexSearcher may impact performance also.
