Summary: RangeFetchMapCalculator should not try to optimise 'trivial' ranges Key: CASSANDRA-13664 URL: https://issues.apache.org/jira/browse/CASSANDRA-13664 Project: Cassandra Issue Type: Bug Reporter: Marcus Eriksson Assignee: Marcus Eriksson Fix For: 4.x RangeFetchMapCalculator (CASSANDRA-4650) tries to make the number of streams out of each node as even as possible. In a typical multi-dc ring the nodes in the dcs are setup using token + 1, creating many tiny ranges. If we only try to optimise over the number of streams, it is likely that the amount of data streamed out of each node is unbalanced. We should ignore those trivial ranges and only optimise the big ones, then share the tiny ones over the nodes. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
