Mars Hall resolved PIO-115. --------------------------- Resolution: Fixed > Cache name-to-ID lookups for Storage app & channel > -------------------------------------------------- > > Key: PIO-115 > URL: https://issues.apache.org/jira/browse/PIO-115 > Project: PredictionIO > Issue Type: Improvement > Components: Core > Affects Versions: 0.11.0-incubating > Reporter: Mars Hall > Assignee: Mars Hall > > When stress testing the Universal Recommender with high-concurrency HTTP/REST > queries, we observed that Elasticsearch traffic was majority composed of > requests resolving the Storage app's name & channel, over and over and over > again! In this case, [each per-query call to > `LEventStore.findByEntity`|https://github.com/heroku/predictionio-engine-ur/blob/master/src/main/scala/URAlgorithm.scala#L694] > re-resolves the app name to an ID. > Implement memoization for the function that performs these name-to-ID > lookups, so that only one set of lookups is performed per process for each > app+channel combination. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
