Vladimir Sitnikov reassigned CALCITE-3661: ------------------------------------------ Assignee: Vladimir Sitnikov > Derive rowCount statistics for tables in ReflectiveSchema that are based on > arrays/collections > ---------------------------------------------------------------------------------------------- > > Key: CALCITE-3661 > URL: https://issues.apache.org/jira/browse/CALCITE-3661 > Project: Calcite > Issue Type: Bug > Components: core > Affects Versions: 1.21.0 > Reporter: Vladimir Sitnikov > Assignee: Vladimir Sitnikov > Priority: Major > > ReflectiveSchema is used quite common in Calcite tests, however, it misses > statistics, so every reflective table is assumed to have 100 rows which makes > it hard to understand if the optimizer is making reasonable decisions (e.g. > join ordering). -- This message was sent by Atlassian Jira (v8.3.4#803005)
