Summary: Reduce FST's ram usage Key: LUCENE-6617 URL: https://issues.apache.org/jira/browse/LUCENE-6617 Project: Lucene - Core Issue Type: Improvement Reporter: Michael McCandless Assignee: Michael McCandless Fix For: 5.3, Trunk Spinoff from LUCENE-6199, pulling out just the FST RAM reduction changes. The FST data structure tries to be a RAM efficient representation of a sorted map, but there are a few things I think we can do to trim it even more: * Don't store arc and node count: this is available from the Builder if you really want to do something with it. * Don't use the "paged" byte store unless the FST is huge; just use a single byte[] * Some members like lastFrozenNode, reusedBytesPerArc, allowArrayArcs are only used during building, so we should move them to the Builder * We don't need to cache NO_OUTPUT: we can ask the Outputs impl for it -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
