Description

SolrCloud powers critical infrastructure and needs the ability to run quickly with stability. This reference implementation will allow for this.

location: https://github.com/apache/lucene-solr/tree/reference_impl

status: developer alpha, on the verge of developer beta

speed: ludicrous

tests**:

• core: extremely stable with ignores
• solrj: extremely stable with ignores
• test-framework: extremely stable with ignores
• contrib/analysis-extras: extremely stable with ignores
• contrib/analytics: extremely stable with ignores
• contrib/clustering: extremely stable with ignores
• contrib/dataimporthandler: extremely stable with ignores
• contrib/dataimporthandler-extras: extremely stable with ignores
• contrib/extraction: extremely stable with ignores
• contrib/jaegertracer-configurator: extremely stable with ignores
• contrib/langid: extremely stable with ignores
• contrib/prometheus-exporter: extremely stable with ignores
• contrib/velocity: extremely stable with ignores

* Running tests quickly and efficiently with strict policing will more frequently find bugs and requires a period of hardening.
** Non Nightly currently, Nightly comes last.
