Summary: Consider implementing "lookback" merge policy Key: LUCENE-5134 URL: https://issues.apache.org/jira/browse/LUCENE-5134 Project: Lucene - Core Issue Type: Improvement Reporter: Otis Gospodnetic Priority: Minor In http://blog.mikemccandless.com/2011/02/visualizing-lucenes-segment-merges.html Mike mentioned lookahead as something that could possibly yield more optimal merges. But what about lookback? What if some sort of stats were kept about about which segments were picked for merges? With some sort of stats in hand, could one look back and, knowing what happened after those merges, evaluate if more optimal merge choices could have been made and then use that "next time"?
