> Key: CALCITE-576
> URL: https://issues.apache.org/jira/browse/CALCITE-576
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.0.0-incubating
> Reporter: Vladimir Sitnikov
> Assignee: Julian Hyde
> Fix For: 1.1.0-incubating
>
>
> Currently {{getCollationList}} is not consistent with {{RelCollation}} trait
> since a node can have only one collation trait, thus you cannot express the
> node that is sorted on multiple collations at the same time.
> We should either drop {{getCollationList}} in favour of {{getCollation}} or
> make collation trait support multiple "collation lists".
