Maryann Xue commented on CALCITE-1536: -------------------------------------- I like option 2 too, the reason I did it the other way was to limit the short-term changes if they are not final. > Initialize cluster before planner > --------------------------------- > > Key: CALCITE-1536 > URL: https://issues.apache.org/jira/browse/CALCITE-1536 > Project: Calcite > Issue Type: Bug > Reporter: Julian Hyde > Assignee: Julian Hyde > > We should initialize the cluster ({{RelOptCluster}}) before planner > ({{RelOptPlanner}}, or a sub-class such as {{VolcanoPlanner}} or > {{HepPlanner}}). Currently the planner contains important information such as > executor ({{RelOptPlanner.Executor}}), the set of active traits (epitomized > by the {{RelOptPlanner.emptyTraitSet}} method) and the metadata providers, > and the cluster contains a link to a planner, so the planner has to be > created first. > This makes it difficult to use a succession of planners for query planning. > Fixing this issue is a first step towards CALCITE-1525. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
