Michael McCandless commented on LUCENE-8884: -------------------------------------------- Argh!! Not sure how I messed that up ... I’ll fix once I have access to laptop again. Thanks for checking [~jpountz]! > Add Directory wrapper to track per-query IO counters > ---------------------------------------------------- > > Key: LUCENE-8884 > URL: https://issues.apache.org/jira/browse/LUCENE-8884 > Project: Lucene - Core > Issue Type: Improvement > Components: core/store > Reporter: Michael McCandless > Assignee: Michael McCandless > Priority: Minor > > Lucene's IO abstractions ({{Directory, IndexInput/Output}}) make it really > easy to track counters of how many IOPs and net bytes are read for each > query, which is a useful metric to track/aggregate/alarm on in production or > dev benchmarks. > At my day job we use these wrappers in our nightly benchmarks to catch any > accidental performance regressions. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
