find\nthe shards that need to be moved, then choose an optimal home for each\nof them. By default the contraction code will remove shards from nodes\nin the \"decom\" zone, and the rebalancing code will ignore that zone\nentirrely. An optimal home is a node that\n\na) is in the correct zone, and\nb) has the fewest # of shards for the DB among nodes in the zone, and\nc) has the fewest total # of shards among nodes satisfying a) and b)\n\nThe implementation of rebalancing is a bit more complicated. The\nrebalancing algorithm looks roughly like this\n\nFor DB in all_dbs:\n Ensure all nodes have at least (N*Q) div length(Nodes) shards\n Ensure no node has more than (N*Q) div length(Nodes) + 1 shards\nFor node in nodes:\n If node has more than TotalShards div length(Nodes) + 1 shards:\n Donate shard to another node\n\nThe net result is that each database is balanced across the cluster and\nthe cluster as a whole is globally balanced.\n\nThe current version of the module prints out shard move and copy\noperations in a clou-friendly format via io:format. It also returns a\nlist of {Op, #shard{}, node()} tuples representing the operations.\n\nThe rebalancer will stop after generating 1000 operations by default.\nThe limit can be customized by using the 1-arity versions of expand,\ncontract and fix_zoning, but note that the performance of the rebalancer\ndegrades as the number of pending operations increases.\n\nBugzID: 23690\nBugzID: 20770\n" }, { "commit": "2f62e2e5586978bd39d59bad060d5168659e6dc5", "tree": "cc53c0b12982f0b563736ddd6020aab8d7382d85", "parents": [ "a29e6b7556862f82ce416f93ac5cf847f36a276e" ], "author": { "name": "Paul J.
