Summary: Optimize service deployment assignments object Key: IGNITE-5551 URL: https://issues.apache.org/jira/browse/IGNITE-5551 Project: Ignite Issue Type: Improvement Components: managed services Affects Versions: 1.7 Reporter: Alexey Goncharuk Fix For: 2.2 1) The deployment assignment is stored using a map [node ID -> number of assigned services]. However, this assignment is not very effective for cases when service configuration is (maxPerCluster = 0, maxPerNode > 0), because in this case, we can avoid assignment recalculation at all. The assignment for this case may look like (eachNode=N). In this case, the assignment does not change and we can effectively skip it during the reassign loop. 2) We store zero assignment counters, which does not make sense at all - if there are no service deployments for a node, there should be no corresponding entry in the map at all. The size of assignments for (maxPerCluster > 0) configurations is O(number of nodes in the cluster), but it should be O(maxPerCluster). 3) If an assignment did not change, we should not commit the assignment transaction - this is redundant -- This message was sent by Atlassian JIRA (v6.4.14#64029)
