[jira] [Comment Edited] (KYLIN-2721) Introduce a new metrics
framework based on dropwizard metrics
[ https://issues.apache.org/jira/browse/KYLIN-2721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16101592#comment-16101592 ]

-------------------------------------------------------------
dropwizard, yammer, codehale is talking about the same thing (http://ningg.top/yammer-metrics/) let's stop confusing the term.
[~yaho] I still have three questions.
1. You claimed hadoop metrics is less stable, do you have any published evidence?\
2. You claimed codehale is lightweight, but as I calculated hadoop metrics has only ~15000 lines of java code (including test), while latest codehale project (https://github.com/dropwizard/metrics.git) has ~23000 lines of java code. "Lightweight" does not favor codehale
3. Although your proposal serves different purpose with existing QueryMetrics, we still need to avoid two metrics frameworks. That said, If we decide to choose dropwizard, we need to migrate QueryMetrics to use dropwizard ASAP
