------------------------------------
Assignee: Julian Hyde
> ListSqlOperatorTable is inefficient
> -----------------------------------
>
> Key: CALCITE-6024
> URL: https://issues.apache.org/jira/browse/CALCITE-6024
> Project: Calcite
> Issue Type: Improvement
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Priority: Major
>
> {{ListSqlOperatorTable}} is inefficient if it contains a large number of
> operators. It currently examines the operators one by one.
> {{ReflectiveSqlOperatorTable}} (and its subclass, {{SqlStdOperatorTable}})
> builds a map of operators by name (actually two maps, one case-sensitive and
> one case-insensitive).
> {{ListSqlOperatorTable}} should do the same, at least in its immutable form.
