(Updated Oct. 4, 2013, 9:42 p.m.) Review request for samza. Repository: samza Description (updated) ------- adding a buffer gauge for blocking envelope map, so we can inject buffer sizes dynamically on request, rather than updating them constantly. Merge remote-tracking branch 'origin/master' into SAMZA-28 reverse change to common and counters. reverse change to common and counters. enabling metrics for blocking envelope map doing non-locking metrics update in blocking envelope map. lock gauges when we update, since this is not atomic, and there's a race condition between poll and add switch counter to gauge for buffered message count map Diffs (updated) ----- samza-api/src/main/java/org/apache/samza/metrics/Gauge.java 14db2d367c151e9c3d435db29888ab64f74c1d3a samza-api/src/main/java/org/apache/samza/util/BlockingEnvelopeMap.java c1dd27988f130f38adcd39e0bc811b6f8074ca6b Diff: https://reviews.apache.org/r/13912/diff/ Testing ------- Thanks, Chris Riccomini
